My dog is not food obsessed at all, unless it’s meat laying around with easy access. He would care less about a payday, banana, or anything else. I routinely carry food in my handbag, just in case I’m stuck without a good gluten free/dairy free option. Upon entering your house, i guarantee I would completely forget said item was in my bag and not even think about it. However, if I was eating anything meat related I would be extra vigilant to make sure the dogs didn’t get it. Where I’m going with this, is people are not use to certain ‘house rules’, even if they have dogs. I think the best option to protect your fur babies is the self closing door, and I’m sure even then they will find goodies.
