This toy is amazing! I hesitated buying it at first, but I’m so glad I finally did. My dog isn’t interested in toys so it’s very hard to find things for him to engage in on his own. I put half of his breakfast & dinner in this and he’ll stay busy for AN HOUR. He’s very smart so he typically finishes all his other puzzles in a minute. I’ve only had it for a week but he’s on level 4 now and can’t get enough. Splurge on this for your dog!!!!
