Luxating patellas are an orthopedic problem. The patella, or kneecap, of most very small dogs, including the Chihuahua, can very easily become displaced, causing pain and lameness. In mild cases the knee quickly slips back into place on its own, but severe cases must be corrected surgically. Ask your veterinarian to examine your dog's knees regularly, especially if you notice him limping or "bunny hopping" while running.
Dog effigy pots dating to around 1325 AD discovered in Georgia and Tennessee also appear to represent the Chihuahua.[6] In 1850, a pot featuring the Chihuahua-like dogs was unearthed in old ruins at Casas Grandes in the Mexican state of Chihuahua, which dates from 1100–1300 AD showing the long history of such dogs at this site,[5] although most artifacts relating to its existence are found around Mexico City. It has been argued that these pots arrived with survivors from the Casas Grandes site in Chihuahua, Mexico, after it was attacked and destroyed around 1340 AD.

The word “beagle” is thought to have come from certain old French words meaning an open throat, a possible connection to the dog’s musical bay. It is also speculated that the dog’s name might have derived from old French, Celtic or English words meaning small. Beagle-like dogs were probably used for the popular sport of hare-hunting in England during the 1300s, but the term "beagle" was not used until 1475. Hunters would follow the dog on foot and sometimes even carry one in his pocket. There were several sizes of Beagles in the 1800s, but the pocket-size dogs were most popular. These small dogs measured only about nine inches and required the hunter's help while crossing rough fields. Because the smaller Beagles were slower and easier to follow on foot, they appealed especially to women, the elderly, and those who otherwise did not have the stamina or inclination to keep up with an active dog.
A disease that seems to be increasing among Chihuahuas is GME, which stands for Granulomatous Meningoencephalitis. It is becoming more frequent among the apple head Chis. It is, at this time, a very poorly understood central nervous system disease that suddenly strikes without much warning. It comes in three types: focal (lesions in the brain or spine); multifocal (lesions in both brain and spine as well as eyes); and optical (causing blindness. There are several current methods of treating it currently and which continue to be updated as more research is done. While there are methods of controlling it in those dogs who survive the first two weeks, unfortunately, there is no true cure. It can go into remission, sometimes for years, but can always resurface. The medications, testing, etc. in the beginning in order to properly diagnose, the cost is in the thousands and many, many more thousands will need to be spent over the remaining years of the dog's life. While GME occurs in many other breeds (generally the toy breeds though there are some others, there is a tremendous number of Chihuahuas with it. Interestingly, deer head Chihuahua's do not tend to be prone to GME, only the apple-head type.

In 1994, the North American Free Trade Agreement (NAFTA), designed to encourage trade among the United States, Canada and Mexico by eliminating tariffs and lifting many restrictions on various categories of trade goods, went into effect. Because Chihuahua shares a border with the United States, the state experienced tremendous economic growth as a result of the treaty. However, small farmers found that participation in the well-established and competitive North American market was quite difficult.
Glaucoma: This is a painful disease in which pressure in the eye becomes abnormally high. Eyes are constantly producing and draining a fluid called aqueous humor — if the fluid doesn't drain correctly, the pressure inside the eye increases causing damage to the optic nerve and resulting in vision loss and blindness. There are two types. Primary glaucoma, which is hereditary, and secondary glaucoma which is a result of inflammation, a tumor, or injury. Glaucoma generally affects one eye first, which will be red, teary, squinty, and appear painful. A dilated pupil won't react to light, and the front of the eye will have a whitish, almost blue cloudiness. Vision loss and eventually blindness will result, sometimes even with treatment (surgery or medication, depending on the case).
How can you tell whether a Chihuahua puppy will mature at 4 lbs and up? There's a general rule of thumb that says you can take the weight of a Chihuahua puppy at 14 weeks old and double it to estimate his adult weight. So to get an adult who will weigh 4 lbs and up, look for a 14-week-old pup who weighs at least 2 lbs. It's not perfect, but it's usually pretty close.

my comment is for all pit owners as being 1 myself ppl say its all in how ya raise them and i do believe thats true to some extent althjo if ya will recall new articals to where pit bulls have attacked every age from toddlers to old folks and everytime its all the same answer or comment my dog has never offered to bite any one he has never been aggressive a dog has a personality just like humans altho it seems like when a pit bull goes off the deep end there is no bringing them back i no that a pit is not the breed of dog that ranks up to the top or near the top for bites when a pit goes to bite he is very aggressive and will not stop untill its prey is dead thats why it has took me so long to get this breed trust is an issue to make a long story short i told my grand kids if she ever bites with aggression i will have her taken away from here n we shall h=get another beagle ( just saying )
They are a cross between the Old English black and tan terriers (Welsh terrier) and the otterhounds. They are tall and have a very lovable expression, medium hair on the body, and a long elongated face. They have a curly and rough coat, and a soft undercoat. The color is a black and tan combination. During the early 19th century, these dogs were used for sporting events which featured catching of large river rats; hence they possess an instinct to chase small animals. During World War I, these dogs were also used by the armed forces as messengers for mails, and to find wounded soldiers behind enemy lines. Overall, they are loyal, caring, and will guard you and your family.

"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!"
Chihuahuas can usually live with other dogs and cats without problem. They get along particularly well with other Chihuahuas. It is important to socialize the Chihuahua as a puppy to prevent overt aggressiveness. Small children may regard the Chihuahua as a toy, and their teasing can cause it to snap or bite. It is preferable not to leave the Chihuahua with children under the age of 12, unless they are well taught or supervised.

Because of its controversial origins, the Pit Bull is not recognized by the American Kennel Club. This has resulted in the formation of two separate clubs for the specific purpose of registering Pit Bulls. The first was the United Kennel Club (UKC), which was formed in 1898 by founder C. Z. Bennett. The founder’s dog, Bennett’s Ring, was assigned UKC registration number one, making it the first registered Pit Bull in recorded history. The second club, the American Dog Breeders Association (ADBA), began in 1909 as a multiple breed association, but it has been dedicated mainly to Pit Bulls, as the original president, Guy McCord, was an avid fancier and breeder of the American Pit Bull Terrier.


The bull breeds are often grossly misunderstood. The qualities that make these dogs tenacious players in obedience and agility games also attract highly unscrupulous people looking for strong competitors for their dog fighting rings. The sorry result is that bull breeds, in particular the APBT, have gained a reputation over recent years for being dangerous.
Remember that after you’ve taken a new puppy into your home, you have the power to protect him from two of the most common health problems: obesity (which makes other health issues worse) and eating inappropriate objects. Keeping a Beagle at an appropriate weight is one of the easiest ways to extend his life, and close supervision of what he’s chewing on can save you big bucks at the veterinary hospital. Make the most of your preventive abilities to help ensure a healthier dog for life.
We also have a dog we found to be a mix , it turns out he is parsons Jack Russel / chihuahua mix and has turned out the biggest size he could have , we saw both parents and had pick if the litter so we now know we were duped and he was probably brought over with Irish travellers . As much as we love him , we are both pensioners and he is a lot more than we can handle and that’s why we chose a small breed , he was tiny when we had him at ten weeks and we have now discovered he must have been only five weeks old . Everyone should be aware if this when buying a puppy .
Neck, Topline, Body: Neck – Slightly arched, gracefully sloping into lean shoulders. Topline– Level. Body -Ribs rounded and well sprung (but not too much “barrel-shaped”). Tail – Moderately long, carried sickle either up or out, or in a loop over the back with tip just touching the back. (Never tucked between legs.) Disqualifications – Docked tail, bobtail.

I have a 10 year old rat terrier-chihuahua mix who is 17 pounds. He is the sweetest dog I have ever met. He loves people and follows me everywhere around the house. He sleeps most of the day but he needs a daily dose of playtime. The only negative is that he can get aggressive toward other dogs (especially big ones!). But other than that, he is such a sweet and loving companion.

The most important thing to know about the Beagle is that he is a scenthound. His nose is the most important part of his anatomy and his head is always down to the ground, searching for an interesting trail to follow. Beagles have approximately 220 million scent receptors compared to the paltry 5 million or so in people, which makes them very good at picking up scents. Humorist Dave Barry once described his in-laws' Beagle as "a nose with feet."
Other potential concerns are hunting injuries. A Beagle who puts a foot wrong in a hole can break a leg. And Beagles who escape from the yard in search of that smell-good scent run the risk of being hit by a car. Nor is it uncommon for a Beagle to see the veterinarian because he has eaten something he shouldn’t have. Beagles who pig out on fatty foods or scraps they find in the trash frequently end up hospitalized with a case of “garbage can” enteritis or, more seriously, pancreatitis.
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’.
Early Beagles looked different depending on the type of ground over which they were expected to hunt. Houndsmen who lived in the gentle countryside of southern England produced slow and ponderous dogs. Beagles from the rougher terrain of Britain’s border with Scotland were agile with lots of endurance. In the early nineteenth century, breeders worked to standardize the breed so they would have a more uniform appearance and temperament. But even today, they aren’t that different from the Beagles of 200 years ago. If one of those dogs were to come forward into the future, you would still recognize him as a Beagle, and the same is true if a modern Beagle were to be transported to the past.

Some of these tendencies can be helped through early training and socialization. Unfortunately, too many people with Chihuahuas allow them to become little tyrants, displaying manners that would not be acceptable in a larger dog. This dog needs gentle and consistent training from puppyhood on to control his nipping as well as any tendency he has to fight with other dogs. Like many small dogs, Chihuahuas aren't aware of their own size and won't hesitate to challenge a dog many times larger than themselves. Also, like many small dogs, Chihuahuas are difficult to house-train without a lot of consistency and patience.
Finally, a long coat can be a single coat, with no undercoat. A single coat lies flatter against the body than a double coat because there's no undercoat pushing it away from the body. In fact, some long coated Chihuahuas hardly look longhaired at all and are mainly identified by the tufts of hair around the base of their ears and some feathering on their legs, stomach, and tail. A single coat feels the cold more, but is easier to groom and sheds less than a double coat.

Reality: Pit Bulls do not have any special physical mechanism or enzyme that allows them to “lock” their jaws. If you compare a Pit Bull skull to a skull of any other dog breed, you can see with the naked eye that both skulls share the same characteristics and general bone structure. However, one personality trait of the Pit Bull breed is determination. Whatever Pit Bulls do, they do it with a great deal of enthusiasm, and it is this trait that can make it seem like they have a locking jaw when they bite down on something and are determined not to release it.
The general appearance of the beagle resembles a miniature Foxhound, but the head is broader and the muzzle shorter, the expression completely different and the legs shorter in proportion to the body.[29] They are generally between 13 and 16 inches (33 and 41 cm) high at the withers and weigh between 18 and 35 lb (8.2 and 15.9 kg), with females being slightly smaller than males on average.[30]

"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)

I have po my Yorkshire terrier x Jack Russel. He’s kept the white and black coat from his mother a tiny black an white Jack Russel but has the long hair of his yorkie father. I bought him as soon as I saw him and he’s the best thing I’ve ever had. He’s eternally loyal, loving in nature, smart and of course gorgeous. Gets on with my cats and even my late pet mouse paloma and loves my partner and myself and anyone he meets is instantly his best friend. I would have never of bought a small terrier before I usually stick with staffs but I can’t explain how glad I am to have changed my mind hen I saw him.


In several entries you will see that the dog was originally bred for fighting. In noting this, we are simply highlighting the motive for its creation. In no case does this determine the behavior of an individual Pit Bull and under no circumstances does it mean every dog is intended solely for this purpose. All dogs deserve a home with caring and responsible owners willing to meet all their needs. Obviously, clandestine dog fighting is an intolerable practice.
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.
In a 2000 review by the Centers for Disease Control and Prevention, which examines data from both media reports and from the Humane Society of the United States, pit bull-type dogs were identified in approximately one-third of dog bite-related fatalities in the United States between 1981 and 1992. However, the review notes that studies on dog bite-related fatalities which collect information by surveying news reports are subject to potential errors, as some fatal attacks may not have been reported, a study might not find all relevant news reports, and the dog breed might be misidentified.[42] The AVMA has also noted fundamental problems with tracking breed in dog bite-related fatalities.[38] In a 2013 study of 256 fatalities in the United States from 2000 to 2009, the AVMA determined that valid breed determination was possible for only 17.6% of cases.[43]
