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]
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.
In domestic dogs, sexual maturity happens around six to twelve months of age for both males and females,[17][68] although this can be delayed until up to two years old for some large breeds. This is the time at which female dogs will have their first estrous cycle. They will experience subsequent estrous cycles semiannually, during which the body prepares for pregnancy. At the peak of the cycle, females will come into estrus, being mentally and physically receptive to copulation.[17] Because the ova survive and are capable of being fertilized for a week after ovulation, it is possible for more than one male to sire the same litter.[17]

Dogs generally have brown eyes and wolves almost always have amber or light colored eyes.[49] The skin of domestic dogs tends to be thicker than that of wolves, with some Inuit tribes favoring the former for use as clothing due to its greater resistance to wear and tear in harsh weather.[50] The paws of a dog are half the size of those of a wolf, and their tails tend to curl upwards, another trait not found in wolves.[51] The dog has developed into hundreds of varied breeds, and shows more behavioral and morphological variation than any other land mammal.[52]

Experienced pet stylists hired from outside the company must complete a personal skill evaluation by a Petco Certified Pet Stylist or Grooming Salon Leader, as well as four weeks of safety and pet grooming operations training. They must also complete and pass a technical skills assessment within 14 days of hire.
