Prone to rheumatism, slipped stifle, colds and gum problems. Also corneal dryness and secondary glaucoma, due to their protruding eyes. Gains weight easily. Take caution around toxic products such as chocolate or fertilizer. This is a very small breed and it will not take much to poison them. Chihuahuas are often born via cesarean section because puppies are born with relatively large heads. Susceptible to fractures and other accidents in puppyhood. Some Chihuahuas have a molera, an unclosed section of the skull which can remain open throughout life. This makes the dog prone to injury. Has a tendency to wheeze and snore because of their small, short muzzles. Prone to stress, caused by the owners tendency to treat them like little babies. All dogs, even tiny ones, need to feel their owners are strong-minded beings able to handle the entire pack.
These dogs are extremely intelligent and learn commands and tricks with ease. They have a zest for life and love to be involved in everything going on around them. They maintain a puppyish demeanor well into adulthood, and that vitality makes them a joy to live with. Once you have met and gotten to know this breed you will wonder how you ever lived without one.
The Beagle has an average lifespan of 12 to 15 years. While this breed is generally healthy overall, some specific ailments that are known to affect the Beagle breed are patellar luxation, glaucoma, epilepsy, central progressive retinal atrophy (CPRA), hypothyroidism, distichiasis, chondrodysplasia, cherry eye, and keratoconjunctivitis sicca (KCS). Deafness, cataract, hemophilia A, demodicosis, and umbilical hernia are some other health problems that affect the breed, while some major ailments include primary carnitine deficiency (CUD) and intervertebral disk disease. Some exams used to identify these conditions include hip, thyroid, and eye tests.
It is true there have been incidents where children have been attacked and even killed, but this is not limited to the Pit Bull. Families of these victims have, understandably, called for breed specific legislation, placing the blame on the breed itself. However, a nine year long study released in 2013 cites that dog-bite related fatalities in the USA were characterized by ‘coincident, preventable factors’ and that the dog ‘breed was not one of these’[4]. More important was a lack of supervision, failure to neuter the dog, inability of the victim to interact appropriately with dogs, mismanagement, neglect and abuse. Breed specific legislation is a reactionary tack which has little evidence to prove its efficacy. This was substantiated by President Barack Obama, who is quoted in the ASPCA statement.
"Yaya is a 5-year-old APBT my wife and I rescued from the Humane Society in Erie, PA. She is great with other dogs and especially a real lover when it comes to people. She is very loyal and loves to smother us with Pitbull kisses. Having gone through a tragic loss in the family a couple of years ago, she has been the best 'therapist' one could ask for. She can be stubborn sometimes; that trait she gets from my wife!"
Beagles bond with everyone in the family, especially children. They can be rambunctious when playing, however, so they need to be properly socialized and supervised with very young children. In addition, Beagles tend to be "mouthy," grabbing things, including your or your child's hand, with their mouths to play. They do this in fun and can be trained not to do this.

Chihuahuas require regular grooming with a brush and comb for their long coat. The Chihuahua’s claws must be kept trimmed, and its teeth must be checked frequently for tartar buildup. Chihuahuas get cold easily and should be kept in a warm environment. The small nose may cause wheezing or snoring. The Chihuahua should not be overfed. There is typically a soft spot on the top of the skull; this is normal and is usually closed by adulthood. The Chihuahua has a long life span at 14-18 years.

Thank you for the amazing article, filled with great and interesting information! I love such a clear-minded and healthy approach, where one can simply see that people truly know what they're talking about. Too often, as in negative myths, people write "oh they're just wonderful". Which is true!, but, it is better to be educated and have strong facts behind the statement so one can have a trustful argument when speaking – and to really show the people what is TRUE, not a personal opinion – be it in a positive or negative context.
What you are describing is my RatCha to a ‘T’. I swore as I was reading your post I thought I was reading the bio for my babygirl. Such an amazing dog. Only thing for me is I got her as a second hand dog on her way to a shelter, so potty training was never done, nor was she trained at all. So getting her when she was about a year and a half meant that she is pretty much puppy pad trained for life, and sometimes rugs and beds. I know she knows no better, and I have to be vigilant about taking her out. But is she is so shy she wont go potty on a leash. Mine barks a lot as well, but only at things that move outside and sounds that are not in visual range XD. But I will say I wont train her against doing it as it alerts me to everyones presence and that is very useful in a home intruder situation. Anyways. I couldn’t have asked for a kinder, more loving dog, even if she is a littler nervous most of the time.
The majority of Chihuahuas are healthy little dogs, but there are some genetic issues that can affect the breed. You should choose your dog from a breeder who routinely does genetic health screenings on all breeding stock to ensure that the puppies they produce are as genetically sound as possible. Some of the issues that can possibly affect the Chihuahua include potential heart problems (patent ductus arteriosus, mitral valve disease), eye disease, and patellar luxation (loose kneecaps). Idiopathic epilepsy is also known to occur in the breed.

Beagles are excellent with children and this is one of the reasons they have become popular family pets. But as beagles are pack animals, they are prone to separation anxiety,[44] a condition which causes them to destroy things when left unattended. Not all beagles will howl, but most will bark when confronted with strange situations, and some will bay (also referred to as "speaking", "giving tongue", or "opening") when they catch the scent of potential quarry.[45] They also generally get along well with cats and other dogs. They are not too demanding with regard to exercise; their inbred stamina means they do not easily tire when exercised, but they also do not need to be worked to exhaustion before they will rest. Regular exercise helps ward off the weight gain to which the breed is prone.[46]

The two coat varieties of the Chihuahua have slightly different grooming needs. The smooth-coat Chihuahua will need only occasional brushing and regular baths to look dapper, while the longhaired variety should have his coat brushed at least once a week to avoid any tangles or mats. Both varieties should have their nails trimmed regularly. Good dental care is necessary and should include brushing your dog’s teeth, and the vet might also recommend treats designed as part of a tooth-care program. Check the Chihuahua’s ears regularly, and remove any excess wax or debris to avoid ear infections.

While there are different types of Pit Bulls, they do share some common characteristics. Pit Bull breeds are generally muscular dogs with a strong bite and, unfortunately, a bad reputation with some. Incorrect information about Pit Bull attacks or sensationalized stories contribute to this situation. However, much of this has to do with the terrible abuse individuals have suffered at the hands of many owners who have historically engaged them in the vile practice of dog fighting. This does not mean that Staffies, for example, are inherently dangerous dogs.


There is also the issue of puppy mills that supply many pet stores. These are commercial breeding facilities that prioritize profit over decent treatment of dogs. The reprehensible conditions at many of these facilities result in traumatized dogs that have numerous health and behavior issues. By avoiding purchasing a dog originating from a puppy mill, you are voting with your pocketbook and not supporting these practices.
2. Staffordshire Bull Terrier: their weight ranges between 11 and 17 kilos (24 and 37 lbs). They are a compact, muscular and agile dog. While many Pit Bull breeds can show territorial behavior towards other dogs and animals, this breed is noted for its friendly character, particularly with children. They are intelligent, full of vitality and fun. The strong attachment they develop to their owners makes them one of the best family dogs.

Casas Grandes, located in the northern portion of the state, is the most important archaeological zone in Chihuahua. The great Puebloan community of Paquime was the center of the Casas Grandes culture for over 300 years, reaching the peak of its power in the 13th century. It is believed that the population of the city reached 10,000, with most inhabitants living in five- and six-story “apartment” buildings. Featuring small T-shaped doors, a ceremonial area, temple structures, a ball court, ceremonial pyramids and a cross-shaped mound with perfect astronomical orientation, the Paquime ruins spark wonder and admiration.


Air France Safety Category 1 dogs, as defined by the French Ministry of Agriculture, Food and Forestry, are not permitted for transport in the cabin, or as baggage or cargo. These so-called "attack dogs" do not belong to a particular breed, but are similar in morphology to the following: Staffordshire Bull Terriers or American Staffordshire Terriers (pit bulls), Mastiffs and Tosas.[70]
Be sure to follow the advice of the Chihuahua Club of America and seek out a responsible breeder who has done all required health testing for the breed. Those tests include Orthopedic Foundation for Animals (OFA) clearance on the parents' knees and heart, as well as Canine Eye Registration Foundation (CERF) vision testing. The CCA participates in the Canine Health Information Center (CHIC) database and requires all of those tests before an individual Chihuahua can be listed on the CHIC website. You can search the OFA and CHIC websites yourself to see if a pup’s parents are listed.
Owners of a Maltese Terrier mix should also make a concerted effort to socialize their pet, especially within its first 14 weeks of life. This will help your Morkie learn to interact with other dogs and people and ensure that it doesn’t become too attached to you. Socialization will also help curb your dog’s separation anxiety and control their excessive barking.
Distichiasis: This condition occurs when an additional row of eyelashes (known as distichia) grow on the oil gland in the dog's eye and protrude along the edge of the eyelid. This irritates the eye, and you may notice your Aussie squinting or rubbing his eye(s). Distichiasis is treated surgically by freezing the excess eyelashes with liquid nitrogen and then remove them. This type of surgery is called cryoepilation and is done under general anesthesia.
Now, the actual amount of shedding depends on whether the coat is single or double. NOT on whether the coat is short or long, but whether it is double (outer coat plus undercoat) or single (just an outercoat). Remember we talked about single and double coats earlier. Whether a coat is short or long, the double coats shed more than the single coats. Which makes sense.

How do Chihuahuas get along with dogs outside their own family? Often not well. Chihuahuas often raise a ruckus when they spy a strange dog, especially a larger dog. It's as though the Chihuahua wants to convince the larger dog that he is a force to reckon with rather than a helpless prey animal. The Chihuahua may be seeking to protect itself by putting up a blustering facade that tells the other dog to "move along."
The Kennel Club in the United Kingdom and the AKC in the United States recognize only two varieties of Chihuahua: the long coat and the smooth coat, also referred to as longhaired and shorthaired.[19] The term smooth coat does not mean that the hair is necessarily smooth, as the hair can range from having a velvet touch to a whiskery feel. Longhaired Chihuahuas are actually smoother to the touch, having soft, fine guard hairs and a downy undercoat, which gives them their fluffy appearance. Unlike many longhaired breeds, longhaired Chihuahuas require no trimming and minimal grooming. Contrary to popular belief, the longhaired breed also typically sheds less than its shorthaired counterparts. Up to three or more years may be needed before a full longhaired coat develops.
Unfortunately, Chihuahuas under 2 or 3 lbs are at greater risk when it comes to health. Their bones are more fragile. There isn't enough room in their mouth for healthy teeth. They can have difficulty regulating their blood sugar and can go into hypoglycemic shock if they go too long without eating. Their internal organs are often weak and can fail suddenly – you might come downstairs one morning and find them inexplicably dead in their basket.
Allergies: Allergies are quite common in APBT/AmStaffs. Skin allergies are typically caused by such environmental allergens as fleas, grass, pollen, and dust.They can also be food related, but this is less common. Common food allergens include beef, rice, wheat, and corn. Allergies can cause intense itching and discomfort, which means dogs will dig and chew sometimes till they bleed. This is risky because secondary infections can develop in the damaged tissue. To treat allergies, the cause must be identified and removed from the dog's environment if possible. A veterinarian can help you with this, as well as let you know which allergy symptoms can be controlled with medication.
Not all of these conditions are detectable in a growing puppy, and it is impossible to predict whether an animal will be free of these maladies, which is why you must find a reputable breeder who is committed to breeding the healthiest animals possible.  They should be able to produce independent certification that the parents of the dog (and grandparents, etc.) have been screened for common defects and deemed healthy for breeding. That’s where health registries come in.

Chihuahuas frequently have what's called a "molera," or an open fontanelle, which is a soft area under the skin of the forehead where the bony plates of the skull have not fused together. It may eventually close up and become hard, but in some dogs, the molera never fully closes. While many dogs can live a normal lifespan with a molera, some may have a condition called hydrocephalus (fluid buildup in and around the brain), which can cause seizures and even death if not treated. A Chihuahua with a molera can live a perfectly normal life, but he is more prone to head injuries so he’s not the best candidate for a home with rambunctious children or bigger, rougher dogs.


The Beagle today is an easy-going dog with a strong hunting instinct. The breed standard says he can be any hound color, including tricolor, red and white, and lemon. The National Beagle Club offers information as well as breeder and rescue referral. The United Beagle Gundog Federation is the place to go if you’re interested in hunting or field trialing your Beagle.
Just like Apple Head and Deer Head Chihuahuas, Teacup Chihuahuas are from the same breed but have a different appearance. A Teacup Chihuahua on average doesn’t weigh more than four pounds. In a household they may need a little more looking after due to their small size. Teacup Chihuahuas can have either short or long hair. Although a Teacup is much smaller in size, they still have the same confident and energetic personality as a full sized Chihuahua. It is also very risky for Teacup Chihuahuas to have puppies due to their size. It can cause many complications and put their life at risk. [34] Compared to the typical lifespan of a Chihuahua a Teacup's lifespan tends to be much shorter due to the health issues they are more prone to have because of their small size.[35]

This test is not perfect, but it does go some way to show the importance of treating the dog as an individual. This is the stance of the American Society for the Prevention of Cruelty to Animals which states that ‘genetics do not exist in a vacuum’[2]. Many factors influence a dog's behavior, but this is true of all breeds. More important than breed is adequate socialization, humane treatment and early positive experiences in terms of a dog's aggression. By enforcing breed specific legislation, as pointed out by the ASPCA, you only create the illusion of public safety. By treating dogs on an individual basis you will be better able to stop attacks, prevent purposeful mistreatment and educate owners and the public about how to treat a animals safely and humanely.
Throughout the 16th century, the first Spanish settlements were established around haciendas (country estates) and mining operations. Some Franciscan missions and Carapoa villages were also founded in the mid-1500s. Although the military garrisons at El Paso and Ciudad Juárez were both built in 1598, the Spanish colonizers exerted fairly loose control over the region during most of the 16th century.
"These are our Chi babies, from left: Maxwell (6 months), Milo (9 months) and Matilda (also 9 months). While Milo and Matilda are on the bigger side of the Chi scale at 7 and 9 lbs., Maxwell is on the more average size at about 4½ lbs. Milo is a bit more on the lazy side compared to the other two and sometimes will just sit and watch the others play. He is also a bit insecure which we are working on with him. They are all very loving however and are always anxious to share kisses with their humans and with each other alike. Sometimes they'll lie in the sun bathing each other’s faces and making sure they are all looking their best. Then they will burrow in blankets, pillows, etc. until they fluff it up just enough to get comfortable and then proceed to take a long nap. While none of them are the "alpha" (that's the humans job, isn't it?!) our female, Matilda is by far the most bossy out of the group. If she wants to play, you'd better play or else you'll get a "donkey kick" until she gets a reaction. Typical female! (and yes, I can say that because I AM a female! :o)

All terrier mix dogs do have some common characteristics, which they inherit from their terrier parent. Terriers are basically warriors and hunters, and they are extremely brave, energetic, and agile. But when they are with humans, these dogs display an interesting spectrum of temperaments and mood dispositions. Many of the macho terrier dog breeds such as, Jack Russel Terrier, Border Terrier, and Airedale Terrier, have taller and sturdy bodies.

Chihuahuas are saucy and alert, with a mind of their own. They might not be able to talk, but that doesn’t prevent them from letting you know exactly what they want: usually plenty of quality time with their favorite person. Chihuahuas are often devoted to a particular person in the family and can even become obsessive about their desire to be with them and protect them. There’s a name for those dogs: “armpit piranhas.” If they’re being held and someone approaches the person holding them, the Chihuahua will make every effort to protect his person, whether it’s necessary or not.
Pit bull is the common name for a type of dog descended from bulldogs and terriers. The pit bull-type is particularly ambiguous, as it encompasses a range of pedigree breeds, informal types and appearances that cannot be reliably identified.[1] Formal breeds often considered to be of the pit bull-type include the American Pit Bull Terrier, American Staffordshire Terrier, American Bully, and Staffordshire Bull Terrier.[2][3][4] The American Bulldog is also sometimes included.[5] Mixed-breed dogs which physically resemble these breeds often get labelled as "pit bulls" by shelters. Many of these breeds were originally developed as fighting dogs from crossbreeding bull-baiting dogs (used to hold the faces and heads of larger animals such as bulls) and terriers.[5] After the use of dogs in blood sports was banned, such dogs were used as catch dogs in the United States for semi-wild cattle and hogs, to hunt and drive livestock, and as family companions.[6] Despite dog fighting now being illegal in the United States, it still exists as an underground activity, and pit bulls are a common type used.[7][8][9]
