A snuffle mat is an enrichment product designed for dogs to help making eating a joy. Often used to slow down fast eaters, this fabric feeder is a successful alternative to a normal dog bowl.
One of the benefits is that they’re slowing down fast eaters. If you feed your dog their main meal from a snuffle mat, your dog will naturally eat slower. 
Another benefit is that your dog gets to use their nose during the activity, which is hugely satisfying. 
You can also use a snuffle mat to practice self-control exercises with your dog. For example, you can tell your dog to sit and wait while you prepare the snuffle mat.
A snuffle mat is an enrichment toy, and playing with them will make your dog more tired.
