Query: My dog seems to like it but . . .

I cut it up into smaller pieces for my terrier. She really seemed to go for the treat but after about 2 weeks, I think it's what's making her vomit. She is fine on the days I don't give it to her, but the handful of times I did, sure enough, the same day or next day, she would throw up.I'm returning the product. Also, it smells pretty bad. I'll stick to piggy slivers.
