Heart Disease: Heart disease affects these dogs in several forms, with aortic stenosis being most common. Aortic stenosis is a congenital heart defect, meaning it's something the dog is born with. It's an abnormal narrowing of the connection between the left ventricle and the aorta. Some dogs don't have any signs or only minor signs, while others may have little energy or even die suddenly. If your veterinarian hears a heart murmur, a chest x-ray and electrocardiogram can confirm the diagnosis.
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.
Due to their athleticism and diverse breeding background, the Pit Bull breed tends to be hardy, with an average lifespan of 12 to 14 years, longer than many breeds of a similar size. There are some genetic conditions to be watchful for. The Pit Bull tends to suffer from bone diseases such as hip dysplasia, degenerative myelopathy and kneecap dislocation. The Pit Bull can also suffer from skin problems, such as mange and skin allergies, because of its short coat. Other health ailments seen in Pit Bulls include thyroid and congenital heart defects.

There are two varieties of Chihuahua recognised by the AKC– the Smooth Coat (short haired) and the Long Coat (long haired). Both the Smooth and the Long Coats have their special attractions and are equally easy to keep clean and well groomed.[12] The UK Kennel Club considers the two as distinct breeds; mating between the two are not eligible for KC registration.

Beagles are used as detection dogs in the Beagle Brigade of the United States Department of Agriculture. These dogs are used to detect food items in luggage being taken into the United States. After trialling several breeds, beagles were chosen because they are relatively small and unintimidating for people who are uncomfortable around dogs, easy to care for, intelligent and work well for rewards.[65] They are also used for this purpose in a number of other countries including by the Ministry of Agriculture and Forestry in New Zealand, the Australian Quarantine and Inspection Service, and in Canada, Japan and the People's Republic of China.[66] Larger breeds are generally used for detection of explosives as this often involves climbing over luggage and on large conveyor belts, work for which the smaller Beagle is not suited.[67]

Before individual Beagles can be included in the Canine Health Information Center (CHIC) database, the National Beagle Club requires them to have a hip certification from the Orthopedic Foundation for Animals (OFA) or the University of Pennsylvania (PennHIP) and certification from the Canine Eye Registry Foundation (CERF), and test results from the University of California at Davis Veterinary Genetics Lab must be registered with the OFA.
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.

Careful breeders screen their breeding dogs for genetic disease and breed only the healthiest and best-looking specimens, but sometimes Mother Nature has other ideas and a puppy develops one of these diseases despite good breeding practices. Advances in veterinary medicine mean that in most cases the dogs can still live a good life. If you’re getting a puppy, ask the breeder about the ages of the dogs in her lines and what they died of.
This is the oldest breed on the American continent and the smallest breed in the world. Native to Mexico, where it received its name from the Mexican State of Chihuahua. It was only brought to Europe at the end of the nineteenth century. The breeds that were used to make up the Chihuahua are unclear, but some think it originated from the Fennec Fox. The dogs were sacred to Pre-Columbian Indian nations and were also popular pets to the upper class. The dogs are prized for their size and are most valued to some fanciers when they weigh under 2-1/4 pounds (1.3 kg).
"This here is my baby girl Roxy at 2 and a half months old. She is the first Pit I've owned and I must say...I'll never own another breed of dog BUT Pitbulls! I fell in love with the breed 3 years ago when I went on vacation to California (I live in Washington) and I went to a Pitbull rescue... immediately I was surrounded by 15-20 Pitbulls. I've never had so many dogs at once DYING for my attention!!! I knew from that day on there was no other dog I wanted BUT a Pitbull. No one will ever understand a Pitbull unless they own one. The only thing they want in this world, what they live for, is to please you. Make you laugh and just be your companion. There's no such thing as a bad dog... just a bad owner. It frustrates me to hear all these stories about Pitbulls attacking little kids or biting their owners; most of those dogs that you see on the news AREN'T EVEN PITBULLS!!! They are all mostly mutts. How dare someone claim what a Pitbull is when most of those people have never even seen a Pitbull in person. No one believes me when I say Roxy is a purebred because "she's too small to be a purebred Pitbull" when in reality, purebred Pitbull Terriers ARE medium sized dogs—Roxy is 47 pounds now and pure muscle! She's got what I like to call "the Pitbull wiggle" when she gets so excited her whole body wiggles and she "smiles" at me. (I could really go on forever about Roxy!) She warms my heart and I want to cry sometimes just looking at her, and how happy she makes me. They are determined dogs, and have so much passion and fire in their eyes (just like her mamma!). I don't know what I would do without my baby girl!!!"
The Chihuahua (affectionately called 'Chi') may descend either from tiny, hairless Chinese dogs or the South American 'Techichi', a favored pet which was buried with the deceased in the hope they would lead the way to the afterlife. Modern Chihuahuas hail from Chihuahua, Mexico. They are the smallest dog breed and the oldest North American breed. They rocketed to popularity in the U.S when famous Latin musician Xavier Cugat made a Chihuahua his constant public companion, and remain extremely popular to this day. Famous Chihuahuas include the Taco Bell Chihuahua, Ren from 'Ren and Stimpy', and Ducky, the 2007 ‘Guinness Book of World Records’ winner for ‘World's Smallest Living Dog’.
The cost of a Chihuahua puppy varies depending on the breeder’s locale, whether he is male or female, whether he’s longhaired or smooth, what titles his parents have, and whether he is best suited for the show ring or a pet home. Prices can range from $400 to $1,600, sometimes higher for puppies with show potential. The cheapest puppy is not always the best, nor is the most expensive. What matters is that the puppy you buy has been raised in a clean home environment, from parents with health clearances and show titles to prove that they are good specimens of the breed. Often, breeders will have puppies spayed or neutered before placing them. Puppies should be temperament tested, vetted, dewormed, and socialized to give them a healthy, confident start in life.

Valladolid: Junta de Castilla / León: Universidad de León, 2007, p. 244: "even in the desert the tiny dogs could be found, hunting rats, mice, and lizards.

Chihuahuas are intelligent, graceful, and sometimes too brave for their own good. They usually bond with only one person and become highly devoted, frequently kissing the owner's face (with or without approval). The Chihuahua is reserved around strangers, and may attempt to defend their owner, usually with little effect. Chihuahuas are tenacious, proud, and very energetic.
Trim his nails once or twice a month if your dog doesn't wear them down naturally to prevent painful tears and other problems. If you can hear them clicking on the floor, they're too long. Dog toenails have blood vessels in them, and if you cut too far you can cause bleeding — and your dog may not cooperate the next time he sees the nail clippers come out. So, if you're not experienced trimming dog nails, ask a vet or groomer for pointers.
Beagles are intelligent but, as a result of being bred for the long chase, are single-minded and determined, which can make them hard to train. They can be difficult to recall once they have picked up a scent, and are easily distracted by smells around them. They do not generally feature in obedience trials; while they are alert, respond well to food-reward training, and are eager to please, they are easily bored or distracted. They are ranked 72nd in Stanley Coren's The Intelligence of Dogs, as Coren places them among the group with the lowest degree of working/obedience intelligence. Coren's scale, however, does not assess understanding, independence, or creativity.[42][43]

"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!"

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.
Everything a Beagle does somehow leads back to his nose. His powerful sense of smell overcomes any good sense you might have tried to instill and tells the Beagle to escape from the yard or break into the dog food bag in the pantry or see what’s in the trash. When channeled properly, it’s also what makes him a great arson dog or termite detector, so it all evens out in the end. Just remember that when your Beagle’s nose is down, his “other brain” is turned off.

The American Pit Bull Terrier has been known by many names, including the Pit Bull and the American Bull Terrier. It is often confused with the American Staffordshire Terrier, however, the United Kennel Club recognizes the American Pit Bull Terrier as its own distinct breed. Affectionately known as "Pitties," the Pit Bull is known for being a loyal, protective, and athletic canine breed.
Terriers are very active and fearless dogs who vary greatly in size. They are categorized by their sizes or habits. They sure are well-known for their varied temperament, which can be hilarious, heart warming, and also inspiring at times. Even though they are physically small to medium in size, they make for perfect watch dogs. They are loyal, kind, and very loving, which makes them perfect pets for families too. Here is some more information about a few types of terrier dogs.

The American Pit Bull Terrier (APBT) is one of the most most popular dog breeds. Unfortunately, even after long periods of domestication, there is still a lot of controversy surrounding them and related Pit Bull breeds. This is often due to misunderstanding and misinterpretation of their nature. The truth is that Pit Bull breeds can be among the most loving, affectionate, loyal and beautiful companions a person can have.

Apple head Chihuahuas can have moleras, or a soft spot in their skulls, and they are the only breed of dog to be born with an incomplete skull. This is not a defect; it is a normal adaptation facilitating the passage through the birth canal and growth and development of the domed type of forehead. The molera is predominant in the apple heads and is present in nearly all Chihuahua puppies. The molera fills in with age, but great care needs to be taken during the first six months until the skull is fully formed. Some moleras do not close completely and require extra care to prevent injury.[38]

"Monkey is a 10-week-old Chihuahua. She got her name Monkey because she climbs on my shoulders all the time and adores bananas, so I thought 'Monkey' really fit her. She is very, very playful and is a joy to have. She is completely pad trained now and knows sit! She lives with 2 adults, 2 teenagers (15 and 16) and 2 little kids (7 and 11) and she loves everyone. But, is very attached to me (I'm 16). Monkey is estimated to weigh about 3 lbs. full grown. She is extremely smart and has great manners, surprisingly. Monkey is for sure a lapdog and follows me around everywhere!! Loves car rides and is very well socialized. I've watched Cesar Millan for about 3 years now and have read his book. He's amazing and has taught me so much about dog psychology, he is truly my idol. Monkey is a well-balanced dog and I taught her young not to have the mind set to walk all over me or try to control me in any way. Though she is spoiled rotten, she knows who is boss. I could not imagine my life without my little Monkey and have lots of years to look forward to. I will ONLY have Chihuahuas; they are an amazing breed and truly a joy to have!!"
The phrase “foot hound” is vital to understanding the Beagle’s broad appeal for hunters in England, the Continent, and North America. Unlike larger pack hunters like foxhounds or Harriers, the Beagle could be hunted on foot—no horse was necessary. Those who couldn’t afford to feed and stable a mount, and ladies and gentlemen too old spend a hard day thundering across the countryside on horseback, could easily keep up with a pack of Beagles on foot.
As for eating, well, Beagles will try to eat anything. They are professional food thieves, and they will eat anything that even looks like it might be food, including things that you wouldn’t imagine would interest them. If nothing else, living with a Beagle will teach you, your spouse and your kids not to leave food of any kind within a Beagle’s nose range.
