My monsters attacked the oreo cookies while I was outside this morning. 2 empty packages were found in the dog run. Maybe a package worth or a bit more could have been all that was eaten as both had been opened previously. We have 4 dogs and so don't know who got what. Our vet did not seem overly concerned- maninly to watch for vomiting/diarrhea/ or lethargy. The packages list chocolate as the last ingredient used as a flavoring. This makes me suspect there is not much actual chocolate in the cookies. Being a worrier by a nature I thought I would ask if this sounds appropiate or if there were other things to watch for- Sigh... never a dull moment with these guys.
