This enzyme will maintain the oral hygiene of your pet and can whiten their teeth.

Vitamin C is vital to human survival, but it has a surprising effect on dogs. Yes, it boosts the immune system, but it can also act as a calming agent. According to certain studies done, when a dog is stressed it runs through a large amount of vitamin C. Stocking your pet up on berries could help rebuild these stores. Berries contain a fair amount of naturally occurring sugar, and therefore should not be excessively fed to your dog. They do however make for a tasty treat.
