I'm reporting on our fawn Dutchie pup, tentatively named Tara. In general, she is doing great! I could go on and on about her talents, including her excellent temperament and adaptability. However, one recent problem is fairly acute: when she got here, I started feeding her Origen Large Breed Puppy chow, along with chicken as you recommended. When reading more, I decided to try her on Fromm's, and since they were out of Large Breed Pup, I got a small sack of beef and lentil. Wrong move, apparently. She loves it, but immediately got diarrhea. That was on Friday, and the diarrhea is persisting, even back on the Origen. I know some stomach upset is to be expected with a change, but she had absolutely no GI problems coming from Michigan to Washington. Advice? Thanks!
