Dog Toys - Mental Simulation
These are toys designed to mentally stimulate your dog. They can be used to help manage certain behaviours, as necessary.
Dog bowl/feeder - This is not really a toy, but a great product to help slow down fast eaters and prolongs. That will prolong your dog's eating pleasure as well as being mentally stimulating
Treat balls - there are a lot of these on the market. Amazon have a good selection. Look for one that is a suitable size - and durable too if your dog is a strong chewer. You'll want one that can go in your dishwasher too.
