The smallest breed of dog, the Chihuahua has a controversial history. One theory holds that it originated in China and was brought to the New World by Spanish traders, where it was then crossed with small native dogs. The other theory contends that it originated entirely in Central and South America, descending from the native Techichi. A small red dog was believed to guide the soul to the underworld, and every Aztec family kept such a dog that was buried with any deceased family member. To make matters worse for the Techichi, the Toltecs and their conquerors, the Aztecs, often ate dogs and the Techichi may have sometimes been on the menu. Despite what may have been short lives, the Techichis apparently were well cared for during life by the priests or their families. In fact, the most likely origin of the Chihuahua is a combination of these theories: the native Techichi was probably crossed with tiny hairless Chinese dogs, but again the date when this occurred is controversial.

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.
"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!"
Another myth about Pit Bull type dogs is that they have a locked jaw which is impossible to break. While many of these dogs do indeed have a strong bite, it is a myth that their jaw locks. It can be broken using a bite stick or by some of the other ways mentioned in our article on breaking a Pit Bull's bite. Another important factor in Pit Bulls is the tendency to dock their tails and ears which makes it more difficult to recognize the signs of aggression in these dogs.

How a Chihuahua behaves depends on the genetic temperament of their parents and grandparents.[22] Their small size makes them delicate and vulnerable to injuries and attacks from larger animals. Like all dogs, they benefit from appropriate socialization and training.[23] Chihuahuas tend to learn better when being rewarded with a treat or positive reinforcement. With the proper training a Chihuahua needs this dog can be extremely intelligent. The way you train your dog will influence their behavior.[24]


Pit Bulls can be loving and wonderful dogs for individuals and families. It is only with proper understanding and consideration that their reputation can be changed and that people can really start to appreciate this breed appropriately, just as it is with any breed of dog. As always, we encourage readers to trust empirical evidence and rigorous study carried out by evidence based programs.
With a compact size, easy-care coat and happy nature, the Beagle has long had a place as one of the most popular breeds for families. Beagles are also used as scent detection dogs at U.S. airports, where their friendliness allows them to search for weapons, drugs, and illegal food items without making passengers nervous the way a larger “police dog” might. The breed was developed in England to hunt rabbits, and Beagles are still happiest when following their noses. For that reason, they belong to a category of dogs known as scenthounds.
A very common misconception is that APBTs are muscle-bound hulks that weigh in around 85 pounds (39 kg) or more and this is generally not the majority. Most of the APBT's that are that large have been crossed with other breeds and are being called American Bullies. The general public often gets American Bullies mixed up with the American Pitbull Terriers. American Pitbull Terrier vs. American Bully
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]
Dogs of either coat type may be identified as either "apple head" or "deer head" Chihuahuas, particularly in the United States. Apple heads have rounded heads, close-set eyes, and relatively short ears and legs. Deer heads have flat-topped heads, more widely set eyes, larger ears, and longer, more slender legs. Deer heads were the breed standard conformation in the mid-20th century, but current breed standards defined by registries such as the AKC specify the apple-head conformation.[13]
He is a sweet dog inside our home and with friends and family, although territorial when in the patio. A few months ago my brother took him to the vet because he was limping. Everything was fine until he spotted another pitbull in the room. An embarrassed moment there, my brother who is a body builder, had to control and carry him out and we had to call another vet to prepare a separate room for him. No problem at the other vet's place, however no pitbulls there.

There are two Beagle varieties: those standing under 13 inches at the shoulder, and those between 13 and 15 inches. Both varieties are sturdy, solid, and “big for their inches,” as dog folks say. They come in such pleasing colors as lemon, red and white, and tricolor. The Beagle’s fortune is in his adorable face, with its big brown or hazel eyes set off by long, houndy ears set low on a broad head.
Forequarters: Shoulders – Lean, sloping into a slightly broadening support above straight forelegs that set well under, giving free movement at the elbows. Shoulders should be well up, giving balance and soundness, sloping into a level back (never down or low). This gives a well developed chest and strength of forequarters. Feet – A small, dainty foot with toes well split up but not spread, pads cushioned. (Neither the hare nor the cat foot.) Dewclaws may be removed. Pasterns – Strong.
Because it is a highly energetic and active breed, the American Pit Bull Terrier requires daily exercise — the more vigorous the better — to overcome boredom and possibly destructive behavior. Like the Greyhound breed, the Pit Bull has a particularly strong prey drive and may chase retreating animals. Taking a Pit Bull on a leashed walk is undoubtedly an important part of socializing it to "play nice." However, care must always be taken to keep the Pit Bull on its leash, to prevent it from running off if it should spot a potential prey animal.
Beagles may be prone to epilepsy, but this can often be controlled with medication. Hypothyroidism and a number of types of dwarfism occur in beagles. Two conditions in particular are unique to the breed: "Funny Puppy", in which the puppy is slow to develop and eventually develops weak legs, a crooked back and although normally healthy, is prone to a range of illnesses;[49] and Musladin-Lueke Syndrome (MLS) in which the eyes are slanted and the outer toes are underdeveloped but otherwise development is as normal.[50] Hip dysplasia, common in Harriers and in some larger breeds, is rarely considered a problem in beagles.[51] Beagles are considered a chondrodystrophic breed, meaning that they are prone to types of disk diseases.[52]
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.
