One of my dogs can tolerate this new formula. My other little one only eats it once in a while and everytime she does, she has diarrhea. I'm sick of it. The old formula was so great, they both ate it for 11 & 12 years. Nutro decided to change the formula and make the kibble smaller. It also stinks when it's in the bowl The poop stinks also. The other formula smelled so good, evn to me. WHY? I've called Nutro and they had some lame excuse about the sweet potato being healthier. Nah, not going to go for that. Don't know what to do.
