My puppy Walter is amazing! We love him so much and are having so much fun with him. One member of our family does NOT love Walter and his name is Simba. Simba is a cat who would rather crawl through glass than hang out with Walter. I'm going to suggest Walter try "nibbling" on him, like this dog. I'll let you know how it goes.
