These toys are fantastic. They build concentration, problem solving, frustration tolerance and are just great fun to do together. They encourage dexterity (using noses and toes) too.
We think these toys are best done together so that you can reward your dog for approaching it calmly and not simply trying to flip it over to release the treat.
These toys do have a difficulty grading, but we actually find it varies greatly by the dogs natural behaviour preferences when searching and manipulating objects - the easiest toy for some can be pretty hard for others.
