I took My bull terrier to puppy school back a few years ago and They really pushed Us to buy the small puppy toys that You can put snacks inside of ? I am not really sure of the name of them but there are a few different ones out there. anywho, They said to put peanut butter in the little holes or even the cheese spread or the Pup's favorite snack and give it to them just before walking out the door of course I am a housewife so I am lucky to have never needed to try it but its a idea !
They said the pups start to look forward to when You leave LOL.
Well,It's a idea
