For a happy dog life, it's important to regularly challenge the dog mentally in addition to physical activity. The Karlie dog toys from the Doggy Brain Train series provide meaningful engagement in this regard. The dog is meant to search for its reward by opening hiding spots through lifting plastic cones or pulling and moving sliders. The high-quality and sturdy wooden board, along with the plastic parts used, are robust, lightweight, and hygienic to clean. This way, both dog and owner can enjoy this great toy for a long time. Various versions are available that can be connected using two linking elements, adding even more variety to playtime with the intelligence toys. Once a hiding spot's mechanism has been figured out, the dog must concentrate again for the next challenge to receive its reward. Of course, its humans should support this process by helping with the puzzles and initially guiding the dog in the right direction. This intense interaction strengthens the bond between human and animal and aids the dog in building trust. It's ideal for creating and solidifying a special relationship.
