Human emigrants from Siberia that came across the Bering land bridge into North America likely had dogs in their company. Although one writer[139] even suggests that the use of sled dogs may have been critical to the success of the waves that entered North America roughly 12,000 years ago,[139] the earliest archaeological evidence of dog-like canids in North America dates from about 9,400 years ago.[132]:104[140] Dogs were an important part of life for the Athabascan population in North America, and were their only domesticated animal. Dogs as pack animals may have contributed migration of the Apache and Navajo tribes 1,400 years ago. This use of dogs in these cultures often persisted after the introduction of the horse to North America.[141]
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[87]. 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.[88]
Brush the dog's teeth.[2] Ideally, brushing your dog’s teeth every day with dog toothpaste is the route to healthy teeth and gums. Use dog toothpaste instead of human products, so you don't poison your dog with fluoride. If there is any chance that you may get bitten by your dog, do NOT attempt to brush your pet’s teeth. At any point, if the dog gets overwhelmed, give him a break to calm down.
