Probiotics for Animals Are Recommended Over Vitamins
We used to think that vitamins were the way to go, but without a healthy gut, vitamins can go to waste. Animals given probiotics during times of wellness, when they are not sick, is the best way to avoid developing allergies in dogs and cats specifically.
Also, a healthy gut balanced with good flora will actually help your pet produce his own natural vitamins and absorb more nutrients from his food.
Give your pet an animal-specific probiotic.
When is the best time to start giving my dog probiotics?
As early as possible. Research suggests that puppies given a healthy dose of probiotics to seed the gut early in life have the best developed immune systems later in life.
