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]

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]
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.
The American Kennel Club recognizes two separate varieties of beagle: the 13-inch for hounds less than 13 inches (33 cm), and the 15-inch for those between 13 and 15 inches (33 and 38 cm). The Canadian Kennel Club recognizes a single type, with a height not exceeding 15 inches (38 cm). The Kennel Club (UK) and FCI affiliated clubs recognize a single type, with a height of between 13 and 16 inches (33 and 41 cm).
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]
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.

Tiny dogs often come with big health problems, and the Chihuahua is no exception. Many Chihuahuas live long, healthy lives, but conditions seen in the breed include breathing difficulties caused by a windpipe that collapses in on itself; luxating patellas; eye disorders; congestive heart disease; certain neurological conditions including hydrocephalus (fluid buildup in and around the brain), neuronal ceroid lipofuscinosis, a condition in which fatty pigments in the brain cause the progressive loss of brain function, and atlantoaxial subluxation, a neck deformity that may require surgical correction; obesity; and dental problems caused by the small size of their mouths. 
Epilepsy: This is a neurological condition that's often, but not always, inherited. Epilepsy can cause mild or severe seizures that may show themselves as unusual behavior (such as running frantically as if being chased, staggering, or hiding) or even by falling down, limbs rigid, and losing consciousness. Seizures are frightening to watch, but the long-term prognosis for dogs with idiopathic epilepsy is generally very good. It's important to take your dog to the vet for proper diagnosis (especially since seizures can have other causes) and treatment.

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.
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.
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]
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]
Dog owners in the United States can be held legally liable for injuries inflicted or caused by their dogs. In general, owners are considered liable if they were unreasonably careless in handling or restraining the dog, or if they knew beforehand that the dog had a tendency to cause injury (e.g., bite); however, dog owners are automatically considered liable if local laws hold an owner strictly liable for all damage caused by their dog, regardless of carelessness or foreknowledge of a dog's tendencies. Homeowners and renters insurance policies typically provide liability coverage from US$100,000–300,000 for injuries inflicted by dogs;[66] however, some insurance companies limit their exposure to dog bite liability claims by putting restrictions on dog owners that they insure. These restrictions include refusing to cover dog bites under the insurance policy, increasing insurance rates for homeowners with specific breeds, requiring owners of specific breeds to take special training or have their dogs pass the American Kennel Club Canine Good Citizen test,[67] requiring owners to restrict their dogs with muzzles, chains, or enclosures, and refusing to write policies for homeowners or renters who have specific breeds of dogs.[66]

The Beagle should do well on a high-quality dog food, whether commercially manufactured or home-prepared with your veterinarian’s supervision and approval. Any diet should be appropriate to the dog’s age (puppy, adult, or senior). Some dogs are prone to getting overweight, so watch your dog’s calorie consumption and weight level. Treats can be an important aid in training, but giving too many can cause obesity. Learn about which human foods are safe for dogs, and which are not. Check with your vet if you have any concerns about your dog’s weight or diet. Clean, fresh water should be available at all times.


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.
I have a terrier maltese, I believe the terrier is parson or jack Russell. I disagree with the author with some of the notes negative traits. She is by far the best dog I have ever had! Better than every other dog I bring her around too. She flys with me on the plane, not a peep. Rides along for 8 hr drives, she loves to run around outside will play fetch, absolutely loves other dogs and especially kids. Very affectionate. And I’m not even really a dog lover but I fell in love with this one.
We own a 10 lb chi/terrier mix who has some serious itchy under belly hair loss going on. She has tested negative for allergies and has been on hydrolyzed food now for a month with no changes to her hair loss. She also takes appoquel daily. Along with this, she will randomly pee in the house. She seems like a very bright dog, so this trait is very frustrating. Not sure what the next step will be but would appreciate hearing from others in this situation.
Testing of cosmetic products on animals is banned in the member states of the European Community,[74] although France protested the ban and has made efforts to have it lifted.[75] It is permitted in the United States but is not mandatory if safety can be ascertained by other methods, and the test species is not specified by the Food and Drug Administration (FDA).[76] When testing toxicity of food additives, food contaminants, and some drugs and chemicals the FDA uses beagles and miniature pigs as surrogates for direct human testing.[77] Minnesota was the first state to enact a Beagle freedom adoption law in 2014, mandating that dogs and cats are allowed to be adopted once they have completed with research testing.[78]
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.
