Q. My dog ate a whole stick of butter. He is behaving like he is on speed (somewhat hysterical).
A. I wouldn't expect him to behave like that from the butter unless he is desperate to vomit or pass faeces. I would expect him to be vomiting and have diarrhea and feel sick. There is a possibility that it could cause pancreatitis depending on the amount consumed and how sensitive your dog's tummy is. If he is acting like this and it isn't because he is wanting to go outside then it is worth having him checked over by your vet.
