Many people believe that since their dog’s feet are “bare” that they must be really cold on the cold ground. A study from Japan demonstrated that this is not the case. Veins in dog paws are very close to arteries. When the paws begin to cool down, the dog’s heart pumps blood through the arteries causing the paw pads to get warmer. This adaptation was already seen in other species, but it’s exciting to know that it also exists in domesticated animals.
This information will make dog owners feel better about their dog being outside in the cold. The study suggests that booties are not needed to keep dog paws warm. I haven’t seen a dog that actually likes wearing booties, at best they seem to barely tolerate the cumbersome covers.
