Dogs bear their litters roughly 58 to 68 days after fertilization,[17][71] with an average of 63 days, although the length of gestation can vary. An average litter consists of about six puppies,[72] though this number may vary widely based on the breed of dog. In general, toy dogs produce from one to four puppies in each litter, while much larger breeds may average as many as twelve.
The cost to trim a dog’s nails can vary based on whether the dog is at a doggy day care and has the service as an add-on, whether you bring your dog to a groomer’s business, or whether you have a mobile groomer provide nail trimming at your home. Nail trimming costs less than nail grinding, which usually is done with a Dremel or similar tool. Nail trimming should be a regular part of of your dog’s care, as overgrown nails can be painful and cause problems.
You may need to pluck ear hairs from time to time. Ask a veterinarian or professional groomer to show you how to pluck the hairs from your dog's ear safely and correctly. Ear powder makes the process easier and quicker by giving added gripping power to the slippery ear hairs. Be very careful when using hemostats as they may poke inside their ear if used incorrectly or when the dog jerks their head.
Dog communication is how dogs convey information to other dogs, how they understand messages from humans, and how humans translate the information that dogs are transmitting.[103]:xii Communication behaviors of dogs include eye gaze, facial expression, vocalization, body posture (including movements of bodies and limbs) and gustatory communication (scents, pheromones and taste). Humans communicate to dogs by using vocalization, hand signals and body posture.
In 2013, an estimate of the global dog population was 987 million.[104] Although it is said that the "dog is man's best friend",[105] this refers largely to the ~20% of dogs that live in developed countries. In the developing world, dogs are more commonly feral or communally owned, with pet dogs uncommon.[50] Most of these dogs live their lives as scavengers and have never been owned by humans, with one study showing their most common response when approached by strangers is to run away (52%) or respond aggressively (11%).[106] Little is known about these dogs, or the dogs in developed countries that are feral, stray or are in shelters, because the great majority of modern research on dog cognition has focused on pet dogs living in human homes.[107]

In 1758, the Swedish botanist and zoologist Carl Linnaeus published in his Systema Naturae the binomial nomenclature – or the two-word naming – of species. Canis is the Latin word meaning "dog",[21] and under this genus he listed the dog-like carnivores including domestic dogs, wolves, and jackals. He classified the domestic dog as Canis familiaris, and on the next page he classified the wolf as Canis lupus.[3] Linnaeus considered the dog to be a separate species from the wolf because of its cauda recurvata - its upturning tail which is not found in any other canid.[22]
The domestic dog (Canis lupus familiaris when considered a subspecies of the wolf or Canis familiaris when considered a distinct species)[5] is a member of the genus Canis (canines), which forms part of the wolf-like canids,[6] and is the most widely abundant terrestrial carnivore.[7][8][9][10][11] The dog and the extant gray wolf are sister taxa[12][13][14] as modern wolves are not closely related to the wolves that were first domesticated,[13][14] which implies that the direct ancestor of the dog is extinct.[15] The dog was the first species to be domesticated[14][16] and has been selectively bred over millennia for various behaviors, sensory capabilities, and physical attributes.[17]
The price of dog grooming starts around $40 for a full grooming service for a small dog, and around $75 for a large dog. If you have more than one, prices can be significantly lower for the second and third dog. For mobile grooming, where groomers come to you, a full service of ears, nails, anal glands, bath, blow dry, and scissor finish is about $75 for average size dogs.
Typically, you should tip your dog groomer 15 to 20 percent of the service total to show your appreciation for a good job. Tips should be whatever you can afford and are a token of you gratefulness. It's quite common for your groomer to give you extra services at no charge, such as teeth brushing or nail trimming. Keep all this in mind when considering how much to tip. Additionally, there are certain circumstances when you should the tip the groomer a bit more.
In addition, people with pet dogs took considerably more physical exercise than those with cats and those without pets. The results provide evidence that keeping pets may have positive effects on human health and behaviour, and that for guardians of dogs these effects are relatively long-term.[195] Pet guardianship has also been associated with increased coronary artery disease survival, with human guardians being significantly less likely to die within one year of an acute myocardial infarction than those who did not own dogs.[196]

Full-service grooming cost is based on breed, pet size and type of fur or hair. It will be confirmed for you when you meet your stylist at the start of your service, and a standardized rate card based on location is available at your salon. Your stylist will consult with you before each appointment to create a personalized plan that you and your pet will be happy with!
