I have a 6 yr old chow mix and one other dog. For last three years both dogs have been eating out of stainless steel food bowls, on tile floor.
Two days ago, chow mix took one bite of food and jumped backwards. I looked to see if there was a bug in the bowl or something else weird; nothing. He took another bite, jumped back again. Moved bowl to rug from tile floor, he leaned way forward and finished his dinner.
Next day gave him a ceramic old dog dish, put it on the carpet. He ate just fine out of that. WTF???
Any theories?
