I have an almost 11 month old miniature poodle puppy who has endless energy. She LOVES this silly little beginner puzzle toy. It took her a little while to get the hang of it but she was interested from the beginning and when I praised her repeatedly for getting the bugs out of the tree, she caught on fast. They’re not really stuffed, they’re crinkly bugs with squeakers in them and the tree is a non-stuffed crinkly tree. Annie loves anything crinkly (bonus if it has squeakers). She will go after this so many times in a row in the morning. It’s an awesome way to tire her out before I go to work. You can add treats between the bugs in the tree so the pup gets a reward each time — I filled it with Annie’s breakfast kibbles once and she went ham. I’m now on the lookout for any more of these crinkly puzzle toys for her.
