Promising review: "My son's Yorkiepoo stays at my place a lot, mostly because I take him to a nearby university campus, where, well-trained as he is, I can let him off-lead and chase squirrels to his heart's content. He is obsessed with squirrels now, so we thought this would be a fun Christmas toy for him. We followed the advice of other reviewers and supervised to try to delay the death of all the squirrels. We let him play with the tree trunk after he had rooted out all the squirrels and tried to kill them, as a dog will do. He loves the tree trunk — so much so that he makes love to it every time we let him play with it. He is nearly 5 years old, and was neutered as a pup, and never was much for humping, but he goes after that tree trunk like a prisoner on a conjugal visit every time we set it out for him to play with. If we have guests, it's a floor show. He doesn't care. I'm not quite sure what to make of all this, but as long as it makes him happy." —PBH
