Hey is it ok to give a dog treat made for a small dog (less the 20LB) to a border collie (around 35LB)? Im asking because there are different sized dog foods which need to be bought for the dogs size becasue of the amount of fiber, vitamens in them. Im asking because we put small treats into his kong toy and they sit in there really well and the ones sized for him dont really fit so I have to break them and then they fall out. We also use them to train him. Kind of a stupid question but any answer will be appreciated.
