We've had our 3 month shihtz for 2 weeks now. She has more loose stools than hard stoole, I'd say mostly loose stoole. Breeder had her on eukanaba and trainer told us to add a teaspoon of yogurt since she wasn't eating great. Is she stressed still since we haven't changed her food? We do plan on getting her on blue freedom and am wondering if we should start sooner rather than later? Am wonderIng if this can be normal or should I make a vet visit? Thks.
