Beagles are used in a range of research procedures: fundamental biological research, applied human medicine, applied veterinary medicine, and protection of man, animals or the environment.[70][71] Of the 8,018 dogs used in testing in the UK in 2004, 7,799 were beagles (97.3%).[72] In the UK, the Animals (Scientific Procedures) Act 1986 gave special status to primates, equids, cats and dogs and in 2005 the Animal Procedures Committee (set up by the act) ruled that testing on mice was preferable, even though a greater number of individual animals were involved.[73] In 2005 beagles were involved in less than 0.3% of the total experiments on animals in the UK, but of the 7670 experiments performed on dogs 7406 involved beagles (96.6%).[70] Most dogs are bred specifically for this purpose, by companies such as Harlan. In the UK companies breeding animals for research must be licensed under the Animals (Scientific Procedures) Act.[73]
Chihuahuas (and Chihuahua crosses and mixes) are frequently available from Dog Rescue groups. Chihuahuas may be turned over to Rescue because of housebreaking problems, or barking, or general nastiness when unsocialized or treated like babies. Other Chihuahuas are given up simply because of changed family circumstances, and these dogs may have no behavior problems at all.
Having a solid structure, the Beagle resembles a Foxhound. Hunters can follow the dog on foot, and the tuneful bay of the Beagle aids hunters in locating the dog from a distance. Because of its moderate size, the Beagle can even be carried to the hunting site, where it can then scurry into the dense undergrowth to look for the target. The dog receives protection against the thick underbrush from its coarse and close coat. And being an amicable dog makes it a great pack hunter, mixing well with other dogs.

All dogs have the potential to develop genetic health problems, just as all people have the potential to inherit a particular disease. Run, don’t walk, from any breeder who does not offer a health guarantee on puppies, who tells you that the breed is 100 percent healthy and has no known problems, or who tells you that her puppies are isolated from the main part of the household for health reasons. A reputable breeder will be honest and open about health problems in the breed and the incidence with which they occur in her lines. Here’s a brief rundown on what you should know.
The experiment was a huge success. Because they are small, friendly, and cute, the Beagles didn't intimidate people who are afraid of dogs, and with their super nose power, they could be trained to identify specific food articles while bypassing those that weren't contraband. Today, members of the "Beagle Brigade" patrol the baggage-claim areas at more than 20 international airports and other points of entry into the United States.

Hip Dysplasia: This is an inherited condition in which the thighbone doesn't fit snugly into the hip joint. Some dogs show pain and lameness on one or both rear legs, but others don't display outward signs of discomfort. (X-ray screening is the most certain way to diagnose the problem.) Either way, arthritis can develop as the dog ages. Dogs with hip dysplasia should not be bred — so if you're buying a puppy, ask the breeder for proof that the parents have been tested for hip dysplasia and are free of problems.
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.
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).
Chihuahuas occur in virtually any color combination, from solid to marked or splashed,[19] allowing for colors from solid black to solid white, spotted, sabled, or a variety of other colors and patterns. Colors and patterns can combine and affect each other, resulting in a very high degree of variation. Common colors are fawn, red, cream, chocolate, brown, mixed, white, and black. No color or pattern is considered more valuable than another.
If you live in a cold or rainy climate, housebreaking will be especially difficult, because Chihuahuas hate both the cold and the rain. In these climates, a COVERED potty area is strongly recommended. Sometimes a doggy door is necessary so your Chihuahua can run outside the moment he feels the urge in his tiny bladder. An indoor litterbox is another option.

Breed standards for this dog do not generally specify a height; only a weight and a description of their overall proportions. Generally, the height ranges between 6 and 9 in (15 and 23 cm);[11] however, some dogs grow as tall as 30 to 38 cm (12 to 15 in).[14] Both British and American breed standards state that a Chihuahua must not weigh more than 5.9 lb (2.7 kg) for conformation.[11] However, the British standard also states that a weight of 4–6 lb (1.8–2.7 kg) is preferred. A clause stating. "if two dogs are equally good in type, the more diminutive one is preferred" was removed in 2009.[15] The Fédération Cynologique Internationale standard calls for dogs ideally between 1.5 and 3.0 kg (3.3 and 6.6 lb), although smaller ones are acceptable in the show ring.[16]
In the 11th century, William the Conqueror brought the Talbot hound to Britain. The Talbot was a predominantly white, slow, deep-throated, scent hound derived from the St. Hubert Hound which had been developed in the 8th century. At some point the English Talbots were crossed with Greyhounds to give them an extra turn of speed.[4] Beagles are similar to the Harrier and the extinct Southern Hound, though smaller and slower.[5][b]

In this AnimalWised article we will try to clarify any doubts that may arise when talking about the different Pit Bull breeds and types you might find. It is vital to be well informed before making any decisions, should you be thinking about adopting one of these wonderful dogs. You will also want to know their different characteristics and features. That's why we bring you these Pit Bull breeds with pictures so you can identify the differences.
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.
Look for a breeder who is a member in good standing of the Chihuahua Club of America and who has agreed to abide by the club's code of ethics. It specifies that its members should evaluate all breeding stock for hereditary faults, never sell dogs to pet stores, and take back Chihuahuas they have bred in the event that the buyer cannot keep them. The CCA lists member breeders on its website, but it’s still important to interview them before buying.
Sites like Petfinder.com and Adopt-a-Pet.com can have you searching for a Chihuahua in your area in no time flat. The site allows you to be very specific in your requests (housetraining status, for example) or very general (all the Chihuahuas available on Petfinder across the country). AnimalShelter.org can help you find animal rescue groups in your area. Also some local newspapers have “pets looking for homes” sections you can review.
In the case of the Chihuahua, blue merle Dachshunds were probably crossed in. Which essentially means that merle Chihuahuas aren't truly purebred. But since genetic diversity is a good thing in living creatures, I don't view cross-breeding as an evil thing. If there are a few Dachshund genes floating around in a merle Chihuahua, that wouldn't bother me.

Progressive Retinal Atrophy (PRA): This is a degenerative eye disorder that eventually causes blindness from the loss of photoreceptors at the back of the eye. PRA is detectable years before the dog shows any signs of blindness. Fortunately, dogs can use their other senses to compensate for blindness, and a blind dog can live a full and happy life. Just don't make it a habit to move the furniture around. Reputable breeders have their dogs' eyes certified annually by a veterinary ophthalmologist and do not breed dogs with this disease.
In 1916, five members of the National Beagle Club purchased 508 acres in Western Loudoun County, Virginia for the purpose of holding field trials. The men who purchased it formed a corporation called Institute Corporate to purchase and own the land, then leasing it to the Institute Foundation that maintains the property for the National Beagle Club, which today is the site of many activities of the National Beagle Club.
The Pit Bull’s origins can be traced back to early 19th-century England, Ireland and Scotland. The canine’s ancestors were the result of experimentally crossbreeding different Bulldog and Terrier breeds for the purpose of bear- and bull-baiting, a blood sport in which the dog was trained to attack until the larger animal was defeated. When baiting was banned in the 1800s, the dogs were then bred for the sport of ratting and dog fighting. European immigrants introduced the Pit Bull breed to North America.
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.

As field dogs they are prone to minor injuries such as cuts and sprains, and, if inactive, obesity is a common problem as they will eat whenever food is available and rely on their owners to regulate their weight.[49] When working or running free they are also likely to pick up parasites such as fleas, ticks, harvest mites, and tapeworms, and irritants such as grass seeds can become trapped in their eyes, soft ears, or paws.[56]
