I might suggest simply taking your dog off of these treats.
The producer and the vet may or may not be helpful.
I gave my #9 toy Poodle Nutro treats. She loved them. Appetite decreased, one time had blood in stools. Vet was concerned about her high liver enzymes, neither of us could figure out what she might have gotten into. Unlike many dogs, she never (in my observation) ate or chewed on odd objects about the yard or street. Took her off of snacks, she was most disappointed. Then her appetite came back. Left her off of Nutro, but, about a year later she was quiet one morning before a vet appointment, died of liver hemorrage in his office.
Of course it could have been age-related, other problems. But she surely did pick up after a week or so without Nutro sticks.
Now we have given our 3 year old 11# Cockapoo Milkbones. She loves them. In recent months her appetite has a little off in the morning, occasionally threw up bile. Last week threw up her breakfast egg (we share breakfast). I took her off of Milkbones & looked about the internet for information. Wife thinks I am nuts, but I will never feed a dog of mine Milkbone, Nutro or any other pet food store treat again. Think her appetite is back. Asked Vet today to humor me & check her liver enzymes.
Have faith in my own observations, at least in this instance.
Read the ingredients, then fine out what they really are. You would not eat those chemicals & amazing animal parts, why feed them to Dog?.
