I recall buying a talking dog stuffed toy for my pet dog one time. It may have been for my own satisfaction but seeing my Japanese Spitz get mesmerized by the antics of the toy also makes me believe that my dog also loved it.
I know that shopping networks have been around for quite some time. It's been only last month that I finally tried using it to shop for an item. My verdict: It was convenient.
I feel that pet dogs know if you are truly affectionate with them or just faking it. Shop your dog a new trinket to find out. Make sure that it's something that it will respond to.
