Well, the strangest toy my dog (not puppy) claimed was an old plastic dumptruck we had in the backyard from when the girls were little. He carried it around, would attack and "kill" it periodically, and when it was finally warped and punctured, I threw it away. He also attacked and "killed" all of the buckets in the backyard (they have tooth puncture holes, sigh).
hmm, maybe they like your mouse or your remote or your phone because they see you holding it a lot! They're like, "hey, I want to try my human's toy and find out why this is so fun!" (plus, it smells nicely of You)
