When we first got Louise a couple years ago, we got a bunch of dog toys for her. Some she liked, others she had no interest in at all. One was a hollow plastic chew toy that she all but completely ignored, even if we put treats inside it. She would eat the treat, discard the toy and look to us for more. Not exactly working as advertised.
We didn't mind much, since there were plenty of other toys that Louise did enjoy. Then, my wife discovered this post on Owned by Pugs that mentioned filling the toy with peanut butter. What was once old is new again my friends. While I have been at work and have yet to witness this for myself, apparently Louise can't get enough of her new nutty flavoured toy. So thanks, OBP! I think you made Louise's day!
