He's a small dog, Pomapoo (cross miniature poodle with Pomeranian). He has a very big stuffed duck toy that he likes to rag around - and then hump. He also gets excited by a thrown, screwed-up piece of paper with a treat to find inside. Both have disadvantages. His humping is serious, often culminating in a fully extended penis that he has to recover from (with bulbous tip ready for a tie) - even though he is neutered. No ejaculate that I can see. His ripping up the paper leaves quite a mess on the carpet.
So I would like to get him something he can rag, but not hump excessively, and something to hunt/catch/rip that doesn't leave too much mess.
