Neutering reduces problems caused by hypersexuality, especially in male dogs. Spayed female dogs are less likely to develop some forms of cancer, affecting mammary glands, ovaries, and other reproductive organs. However, neutering increases the risk of urinary incontinence in female dogs, and prostate cancer in males, as well as osteosarcoma, hemangiosarcoma, cruciate ligament rupture, obesity, and diabetes mellitus in either sex.
Dog behavior is the internally coordinated responses (actions or inactions) of the domestic dog (individuals or groups) to internal and/or external stimuli. As the oldest domesticated species, with estimates ranging from 9,000–30,000 years BCE, the minds of dogs inevitably have been shaped by millennia of contact with humans. As a result of this physical and social evolution, dogs, more than any other species, have acquired the ability to understand and communicate with humans, and they are uniquely attuned to human behaviors. Behavioral scientists have uncovered a surprising set of social-cognitive abilities in the domestic dog. These abilities are not possessed by the dog's closest canine relatives nor by other highly intelligent mammals such as great apes but rather parallel some of the social-cognitive skills of human children.
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:
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.
A number of common human foods and household ingestibles are toxic to dogs, including chocolate solids (theobromine poisoning), onion and garlic (thiosulphate, sulfoxide or disulfide poisoning), grapes and raisins, macadamia nuts, xylitol, as well as various plants and other potentially ingested materials. The nicotine in tobacco can also be dangerous. Dogs can be exposed to the substance by scavenging through garbage bins or ashtrays and eating cigars and cigarettes. Signs can be vomiting of large amounts (e.g., from eating cigar butts) or diarrhea. Some other signs are abdominal pain, loss of coordination, collapse, or death. Dogs are susceptible to theobromine poisoning, typically from ingestion of chocolate. Theobromine is toxic to dogs because, although the dog's metabolism is capable of breaking down the chemical, the process is so slow that for some dogs even small amounts of chocolate can be fatal, especially dark chocolate.
Clip the dog's nails. 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. 
Trimming your dog’s nails is an important part of keeping your dog healthy and well-groomed. Well-clipped nails are also a factor in your dog grooming costs. When a dog’s nails get too long, they have the potential to break or split, which can cause them pain and mean a costly visit to your local veterinarian. Overly long dog nails can also cause discomfort for your pup, especially if you have hardwood or tile floors. Be sure to calculate regular nail trimming into your budget for dog grooming. The dog groomer may use trimmers to clip the nails, or they may use a small drill (like a Dremel) to grind down the nails. A good professional groomer will know not to clip too close to the base of the nail, where nicking a nerve or a blood vessel could injure your dog. Nail trimming costs can vary based on geographic location and whether you bring the dog to the groomer or if the groomer picks up and drops off your dog. Transportation fees for pickup and drop-off service can add a lot to the cost. A simple dog nail trim may cost between $10 and $30, depending on location. Nail grinding may cost $2-$8 more than standard clipping. Many dog groomers offer discounts for bundled services, so you could get a nail trim at a reduced rate when you purchase it with a bath.

Their long association with humans has led dogs to be uniquely attuned to human behavior and they are able to thrive on a starch-rich diet that would be inadequate for other canid species. Dogs vary widely in shape, size and colors. They perform many roles for humans, such as hunting, herding, pulling loads, protection, assisting police and military, companionship and, more recently, aiding disabled people and therapeutic roles. This influence on human society has given them the sobriquet of "man's best friend".
Dog intelligence is the ability of the dog to perceive information and retain it as knowledge for applying to solve problems. Dogs have been shown to learn by inference. A study with Rico showed that he knew the labels of over 200 different items. He inferred the names of novel items by exclusion learning and correctly retrieved those novel items immediately and also 4 weeks after the initial exposure. Dogs have advanced memory skills. A study documented the learning and memory capabilities of a border collie, "Chaser", who had learned the names and could associate by verbal command over 1,000 words. Dogs are able to read and react appropriately to human body language such as gesturing and pointing, and to understand human voice commands, although a 2018 study on canine cognitive abilities found that dogs' capabilities are not more exceptional than those of other animals, such as horses, chimpanzees or cats.
According to the Humane Society of the United States, 3–4 million dogs and cats are euthanized each year in the United States and many more are confined to cages in shelters because there are many more animals than there are homes. Spaying or castrating dogs helps keep overpopulation down. Local humane societies, SPCAs, and other animal protection organizations urge people to neuter their pets and to adopt animals from shelters instead of purchasing them.
