I’m always on the lookout for mental stimulation toys, both for my dogs as well as for my dog training clients (because so many dogs are just plain bored!) I recently discovered K9 Connectables and decided to give them a try. Because of their buy-2-get-1-free sale, I ended up getting 3 Kibble Bundles (each with 1 Connector plus 2 Originals), as well as 3 Brain Teasers and 3 Tuff Stuffers.
I love the idea of what amounts to chewable Legos for dogs! The dogs love it too!
