So my dog Jax, is a 6 year old husky with some anxiety. I thought this toy would keep him busy while I’m away at work. Now I think this toy is perfect for dogs who are hungry all of the time. My husky is very light eater (his preference, he has his food out all day and he just nibbles at it), but he does love his treats! I put it on the easiest level and I put his favorite treat in the toy, he tried to get it out for a little under 5 minutes and then he was done Lol he wouldn’t even go back and sniff it, unless I was with him, pushing it around. Overall great product, just not for Jax.
