somebodysme- are you really surprised that your dog can’t tolerate popcorn? not even sure why you would feed a dog popcorn at all. some dogs and cats will LET you know if the food is the culprit. My kitten as an example throws up instantly after she eats (this has happened only 2 times in her life) when she cant tolerate the food. And from there on out I simply stay after from that food because I don’t want to play russian roulette with her stomach.
From the sound of it the OP did pin-point that it could be the treats. Or it could be feeding TOO many treats, say because of a training class that uses a treat based reward system.
And Im with Marie on this one. Why throw away your money? Blue is one of the most overpriced 5 star foods out there for what it actually is. Their treats included. Theres much better choices out there that are 4 or 5 star quality.
