I'm starting fresh with a new pound puppy. My 10-month old took off with the bones initially and tried to chew them. I removed them from her and redirected her to the real treasure. After the 2nd round of training she started ignoring the bones and going for the real treat. She now takes her meals in this or her Kong Wobbler. I still have to watch because as I was typing this she finished the game and got bored waiting for me so proceeded to chew up one of the bones.
The 8-yr old owned this in no time. His first time with it he put his paw on the center to hold it in place, then picked up the bones, tossed them to the side and reaped his rewards. He was considerably more slobbery than the girl, so do be aware that these things can get slimed. I'm using other toys with him due to the goo factor, and to offer him more of a challenge since this was far too easy for him.
This has been a great relief for boredom for the 10-month old. She cracked her foot on our patio when the two dogs were running full speed ahead in the yard, resulting in a toe fracture. I am to keep this puppy on limited activity for 4 - 6 weeks so I'm learning all sorts of new tricks to keep her mind active to make up for the lack of physical exertion. Now that she's able to put weight on the foot this toy, the Kong Wobbler, and a plush toy with holes to pull smaller plushes from are helping me do just that.
Good introduction to puzzle toys
Durable But requires training to prevent dogs from chewing the pieces up
Easy to set up
Noisy if your dog manhandles it
Moves all over the floor
Slobber can make the pieces difficult to handle (or just gross)
Takes a little time to set up
Video is the boy on his 3rd attempt. He has a listening problem - he can't hear "sit" when he doesn't want to. :D I have to send him to the crate because he has resource guarding issues I've never been successful at training out of him so to keep things civil I send him away from the game before I refill. If that one piece hadn't escaped, breaking his concentration, he would have finished up pretty darn quick. The girl is less elegant in her execution.
