I swear by Cranimals!
We live in Atlanta. My female dog likes to lay under our deck in the dirt. According to our vet, when we get a lot of rain there is excess amounts of bacteria on the ground. This leads to an increase in UTI cases at the vet, which used to include our girl. Since I've been giving her Cranimals twice a day, she has not had a single case of UTI! Awesome product!
