The Fenrir Hammer is the world's ultimate dog chew toy! Incredibly multi-functional and mentally stimulating, your dog will not be able to get enough of it.

Made from heavy duty, durable rubber, the Fenrir Hammer dog chew toy is designed to help teach appropriate chewing behaviour, whilst still being fun and engaging for dogs less inclined to chew.


The ultimate all-in-one training tool, the Fenrir Hammer can be used for playing and relationship building in the form of fetch or tug games, providing mental stimulation and keeping your dog entertained by filling with dry food, or freezing pâté and other treats for a challenge that will last for hours. The enrichment it provides your dog can even aid with issues like separation anxiety, crate training and destructive behaviour, providing a distraction for your dog and satisfying their natural instincts.

Available in 2 sizes:

The Fenrir Hammer and the Mini Hammer. The Mini Hammer is perfect for young puppies and smaller dog breeds, but for bigger dogs or extreme chewers you will need The Fenrir Hammer. Please check the size comparison to confirm the best hammer for your dog.
