Dogs' Teeth

Many breeds of dogs are the result of human intervention. By selective
breeding, the dogs have been made cuter. Very little dogs and pug-
nosed dogs may have been bred too far into their specialty. The
problem is with their teeth. It seems that their teeth have not
decreased in size as much as their mouths, and when these teeth grow
in, they come in all crooked. These crooked teeth trap food particles
and eventually cause extreme decay and periodontal disease.

You can actually brush a dog's teeth, and should, to help spare them
the pain of mouth problems. To do it, start when the dog is quite
young, and put your finger in their mouths and rub their teeth while
playing with them. They will get used to this, and you can eventually
substitute a toothbrush for your fingers. Don't use human toothpaste,
which is designed to be spit out. Use a small amount of baking soda.
Also starting at a young age, make sure your dog or cat gets crunchy
food in their diet every day to help reduce plaque buildup.
