I bought my dog the oinkie chicken tender twist sticks. Not knowing the bad reviews of course. All of a sudden I started seeing clumps of undigested white material in my dogs stool. Then a day or 2 later my dog got so sick he started vomiting the same material all over the house. When my daughter and I looked at it closely the white material was the twists that Hartz use to wrap the chicken jerkey around. It was all undigested and made my dog so sick he just laid around for days. I will NEVER give this crap to my dog again or any other Hartz product EVER again. I hope they go out of businesses.
