There are many different shapes for dog tails: straight, straight up, sickle, curled, or cork-screw. As with many canids, one of the primary functions of a dog's tail is to communicate their emotional state, which can be important in getting along with others. In some hunting dogs, however, the tail is traditionally docked to avoid injuries.[38] In some breeds, such as the Braque du Bourbonnais, puppies can be born with a short tail or no tail at all.[39]
Try to avoid getting shampoo into your dog's eyes. It could seriously irritate them. Put shampoo into your hands before spreading it into your dog's fur instead applying it straight from the bottle. Don't let suds get into your dog's eyes when rinsing, and gently squeeze his ears shut to keep water out when working on those areas. You can place cotton balls in your dog’s ears to prevent water from getting into the ear canals. Make sure to remove the cotton balls when you're done. You may also keep the cotton balls in during the drying process as the noise of the dryer scares them.
Dogs demonstrate a theory of mind by engaging in deception[89]. An experimental study showed compelling evidence that Australian dingos can outperform domestic dogs in non-social problem-solving, indicating that domestic dogs may have lost much of their original problem-solving abilities once they joined humans.[90] Another study indicated that after undergoing training to solve a simple manipulation task, dogs that are faced with an insoluble version of the same problem look at the human, while socialized wolves do not.[91] Modern domestic dogs use humans to solve their problems for them.[92][93]

Raised grooming tables and bath tubs keep you from bending your back and hurting yourself. Any table or sturdy surface could serve as a makeshift grooming table, but always have a non-skid surface for the dog to stand on. That means no wheels on the table. Hardware stores usually carry rubber-backed or rubber runners sold by the yard that you can cut to size of any surface.
Clear the dog's eyes. White-haired breeds or those with large eyes that water a lot (Pekingese, Pugs, Pomeranians, etc.) may need more maintenance in this area than others. Depending on your particular dog, this step may be a simple matter of wiping or pulling eye debris away from the corners of the eyes. Long-haired or white-haired dogs may need special attention to make sure that all gunk is out of the coat, as they may get tear stains. You can buy products made for removing "tear stains" from a white coat at a pet supply store.

Clip the dog's hair methodically.[9] You can place the blade against the body safely, so long as you don't press the blade strongly into the skin. Brush against the direction of hair growth(back-brush) before running the clippers the other direction; with the direction of hair growth. Using the clippers against the growth of hair will have the same effect as back-brushing, but will leave a shorter length than the clipper blade that you are using. If you want to shave against the growth of hair, a blade size gets two blade sizes smaller when cutting against the grain. For example, when cutting with 4# against the grain check how long a 7# leaves behind when cutting with the grain. Move the clippers surely, but slowly across the dog's body to remove the hair — moving too fast might leave uneven lines. Always move the blade with the direction of the hairs' growth unless you want a shorter length than your blade claims to leave. Begin at the neck, then move down to the shoulders, under the ears, and toward the chin, throat, and chest areas. DO NOT use a size seven or any skip blades around the throat area or any flaps on the body that can fit between the teeth, such as the Achilles' tendons, arm pits, genital area, tip of tail, or anus. Then, clip the dog's back and sides. Finally, clip the hair on the dog's legs. Be careful when cutting the neck with any blade as it's the most dangerous to cut. Never cut straight down, do so at angles to avoid flaps you can't see in the neck getting cut.
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]
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]
Long fur on the paws acts as a trap for grass seeds, grit, or even ice, so regular trimming is advisable. Use a pair of curved scissors with rounded tips. Work on one toe at a time and twirl the fur growing between two toes between your finger and thumb, and then snip the hair off at the base. Be careful never to pull on the fur, which elevates the skin and makes cutting it more likely. If you cannot see where the skin ends and the fur starts, then slide a comb through the fur at skin level, and using the scissors cut on the safe side of the comb. Repeat for each toe on each paw.
Clip the dog's fur after it's completely dried. If you plan to clip your dog's hair, make sure to read the directions that came with the clippers. Get an information book or video, or consult with a groomer about the proper use of your clippers. Make sure that the clipper blades are sharp and the clippers well lubricated. If the blades are not sharp, they can pull on the hair.
A Colorado study found bites in children were less severe than bites in adults.[179] The incidence of dog bites in the US is 12.9 per 10,000 inhabitants, but for boys aged 5 to 9, the incidence rate is 60.7 per 10,000. Moreover, children have a much higher chance to be bitten in the face or neck.[180] Sharp claws with powerful muscles behind them can lacerate flesh in a scratch that can lead to serious infections.[181]

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.

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.
It has been suggested that the most significant benefit would have been the use of dogs' robust sense of smell to assist with the hunt.[136] The relationship between the presence of a dog and success in the hunt is often mentioned as a primary reason for the domestication of the wolf, and a 2004 study of hunter groups with and without a dog gives quantitative support to the hypothesis that the benefits of cooperative hunting was an important factor in wolf domestication.[137]
Take extra care with dark-nailed dogs not to clip to the quick (blood vessel). Go slowly, and only take a little bit off at a time. Dremeling is much safer and easier to avoid hitting the quick, as it shaves only a little bit at a time. Use a cordless pet-safe Dremel tool, as the corded ones will not stop turning if they catch hair. Don't dremel for too long as it will burn the nail and prolong the trimming process for the dog which causes more stress. The best recommended process is trim first then dremel to shorten a little bit and round out the nail do it's not sharp.

Domestic dogs have been selectively bred for millennia for various behaviors, sensory capabilities, and physical attributes.[17] Modern dog breeds show more variation in size, appearance, and behavior than any other domestic animal.[17] Dogs are predators and scavengers, and like many other predatory mammals, the dog has powerful muscles, fused wrist bones, a cardiovascular system that supports both sprinting and endurance, and teeth for catching and tearing.

Some breeds of dogs are prone to certain genetic ailments such as elbow and hip dysplasia, blindness, deafness, pulmonic stenosis, cleft palate, and trick knees. Two serious medical conditions particularly affecting dogs are pyometra, affecting unspayed females of all types and ages, and gastric dilatation volvulus (bloat), which affects the larger breeds or deep-chested dogs. Both of these are acute conditions, and can kill rapidly. Dogs are also susceptible to parasites such as fleas, ticks, mites, hookworms, tapeworms, roundworms, and heartworms (roundworm species that lives in the heart of dogs).

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.
Don't overdo bathing. Once every 6 to 8 weeks is typically enough. Professional grooming services are recommended once every 4 to 6 weeks for long haired breeds. Bathing too often can dry out the skin by removing the natural oils. Waterless shampoo can be used between baths to clean feet and other areas. Spot spray directly and sponge off with a damp sponge. Use a hypoallergenic or mild oatmeal shampoo designed for dogs for general bathing. If your pet has a particular skin condition, try hypoallergenic scent free shampoo before the vet. If the condition persists, a medicated shampoo from your veterinarian may be in order. Consult your veterinarian if there are concerns about your pet’s skin.
Dogs have a pair of anal scent glands that sit at the 8.20pm position on either side of the anus. Some dogs produce too much secretion and the glands stretch which causes the dog to scoot on his bottom. The glands can be emptied by applying gentle pressure underneath each gland, milking the secretion up and out onto a piece of cotton wool. Anal sac secretion is unpleasant so wear disposable gloves. Be careful not to squeeze too hard and if in doubt, stop and ask a professional groomer how to empty them.
Dog grooming prices for nail trims can vary based on the the size and temperament of your dog, where the nail trimming takes place, and whether you bundle the trim with other grooming services. The average cost to get your dog’s nails trimmed usually ranges from approximately $10 to $25. Nationally, the average for dog grooming prices is $60-$80, which usually encompasses not only nail trimming but also bathing, haircuts and other services.
Soak your dog thoroughly. Make sure your dog's coat is completely wet before you start applying shampoo to it. If your dog isn't afraid, you can buy and use a hose and water pressurizer attachment for the faucet. This is especially helpful if you have a large dog or one with a double-coat. AVOID getting water in your dog's ears. Water in the ears can cause an infection. Please be sure to only spray water/rinse water up to the dog's neck. The head can be cleaned separately (see below for instructions).
