We have a 3 month shihtzu and we got her over 2 weeks ago. She was on Eukanba with the breeder and we are trying to move her off of it onto Freedom. For her meals, we give her Eukanba and toss some Blue Buffalo Freedom in there (not alot). Her stoole is always loose and I don't know if that is norm for a puppy or if it's food related. Our trainer told us to add rice to it but it hasn't been helping. For the past 2 days, her 1st morning walk has been diarrhea and the rest of the day it's been loose stoole. I feel we are going very slowly with her food transition. She is still on Eukanba with some Freedom in it. I don't think it's a vet issue. She was just there 2 weeks ago and when we spoke about the loose stoole, they took a sample and it was fine. Is it the freedom? Should I stop at this point and consider something else? I don't think it's the Eukanaba as she has always been on it but how do I tell which it is? Do I just feed her eukanaba for a week and see if it's still loose and if she has diarrhea or do I go begin offering more freedom in her meals? She is happy, playful and shows no signs of there being an issue. We feed her 1/3 a cup in the morning and a 1/3 at night. She "almost" finishes it all.
