Every year, between 6 and 8 million dogs and cats enter US animal shelters.[204] The Humane Society of the United States (HSUS) estimates that approximately 3 to 4 million of those dogs and cats are euthanized yearly in the United States.[205] However, the percentage of dogs in US animal shelters that are eventually adopted and removed from the shelters by their new legal owners has increased since the mid-1990s from around 25% to a 2012 average of 40% among reporting shelters[206] (with many shelters reporting 60–75%).[207]

The longest-lived breeds, including toy poodles, Japanese spitz, Border terriers, and Tibetan spaniels, have median longevities of 14 to 15 years.[64] The median longevity of mixed-breed dogs, taken as an average of all sizes, is one or more years longer than that of purebred dogs when all breeds are averaged.[62][63][64][65] The longest-lived dog was "Bluey", an Australian Cattle Dog who died in 1939 at 29.5 years of age.[66][67]
The domestic dog is the first species, and the only large carnivore, known to have been domesticated. Especially over the past 200 years, dogs have undergone rapid phenotypic change and were formed into today's modern dog breeds due to artificial selection by humans. These breeds can vary in size and weight from a 0.46 kg (1.0 lb) teacup poodle to a 90 kg (200 lb) giant mastiff. Phenotypic variation can include height measured to the withers ranging from 15.2 centimetres (6.0 in) in the Chihuahua to 76 cm (30 in) in the Irish Wolfhound; color varies from white through grays (usually called "blue") to black, and browns from light (tan) to dark ("red" or "chocolate") in a wide variation of patterns; coats can be short or long, coarse-haired to wool-like, straight, curly, or smooth.[131] The skull, body, and limb proportions vary significantly between breeds, with dogs displaying more phenotypic diversity than can be found within the entire order of carnivores. Some breeds demonstrate outstanding skills in herding, retrieving, scent detection, and guarding, which demonstrates the functional and behavioral diversity of dogs. The first dogs were domesticated from shared ancestors of modern wolves, however the phenotypic changes that coincided with the dog–wolf genetic divergence are not known.[26]
Dog grooming is so much more than giving your dog a bath. Dog grooming is a broad term that covers all aspects of canine cleanliness and hygiene. The services included in dog grooming will vary based on your needs and what you choose to pay. Unless they are rolling in cowpies or playing in mud puddles, most dogs are okay getting a shampoo bath only as needed. You’ll know when they need it if they smell bad or are bringing dirt into the house. Some dogs, like shepherds and shih tzus, have thick coats that can get matted and tangled without regular care. Pro dog groomers can deftly blow dry a dog’s hair after a bath so that it is shiny and smooth. Dog grooming can include brushing that detangles dog hair and also thins the undercoat to minimize shedding.
In 1999, a study of mitochondrial DNA indicated that the domestic dog may have originated from multiple grey wolf populations, with the dingo and New Guinea singing dog "breeds" having developed at a time when human populations were more isolated from each other.[23] In the third edition of Mammal Species of the World published in 2005, the mammalogist W. Christopher Wozencraft listed under the wolf Canis lupus its wild subspecies, and proposed two additional subspecies: "familiaris Linneaus, 1758 [domestic dog]" and "dingo Meyer, 1793 [domestic dog]". Wozencraft included hallstromi – the New Guinea singing dog – as a taxonomic synonym for the dingo. Wozencraft referred to the mDNA study as one of the guides in forming his decision.[1] The inclusion of familiaris and dingo under a "domestic dog" clade has been noted by other mammalogists.[24] This classification by Wozencraft is debated among zoologists.[25]
Do you have a dog that you get groomed regularly? If you do, you’ve probably wondered how much — or even if — you’re supposed to tip your dog groomer. Treat your dog groomer as you would your own hair stylist. A 15 percent to 20 percent tip is an appropriate amount to show your appreciation for a dog grooming job well done. If your dog didn’t get clean or their nails didn’t get properly clipped, then you certainly don’t have to tip. But if you’re satisfied with the service, consider the tip part of the standard dog grooming price, and just plan it into your dog care budget so you’ll have a happy groomer and a well-groomed dog. Here are a few examples of when you should tip extra:
Clip the dog's nails.[3] If left untrimmed, a dog's nails can curl under into the paw pads or twist toes in a way that causes joint damage. To keep your dog's nails short, clip them regularly, depending on how fast his nails grow. If you can hear his nails on the ground when he walks, that means his nails are touching the ground, and are too long. [4]
Please note that regardless of pet type, we always put safety first. Sometimes pets can stress in new situations. If we feel your pet is too stressed or showing any potential health concern, we may opt to conclude the grooming appointment in order to do what's best for them. Your stylist can help recommend a grooming service for a smooth introduction, such as a Mini Make-Rover. For any potential health concern your stylist will refer you to your veterinarian.
