Input: Meat is so hard & tough. Not for senior dogs missing teeth. Even heating it won't soften it. Don't understand why each variety is so hard to cut in pieces. I understand that switching dog foods can cause upset tummy but her stomach made noises all night & she vomited it up in the morning. Will try again to introduce this food into her diet but I'm apprehensive.
Output:
Dog food small & not for senior dogs. Meat too tough to cut in little bits.
