Bests & Worsts Reviews from Amazon

This is awesome! My border collie’s level of intelligence is a part time job for me. He requires engagement and he figures out everything fast. This puzzle took him a good hour and a half to figure out the first time and every time after that, he sits with this for about an hour. He’s really calm (which he’s normally not) and concentrated with it, methodically moving pieces. I ordered a second, different puzzle a day after we received this first one. It’s easy to clean because the sliding tiles just pop right off but I’ve just been using his regular kibble in it so it hasn’t hardly gotten dirty at all.
