The Little Dog In-Ground Fence™ was designed just for little dogs to wear comfortably, and the In-Ground Cat Fence™, designed just for cats, comes with our lightest collar.
While we recommend your pet be at least 5 or 8 pounds to wear our wireless or in-ground collars, many smaller dogs and even cats can wear collars from other fences. That means you can add your new small dog to your existing system, or you can purchase a wireless fence and collars for each pet.
Our office dogs have personally tested these collars to make sure they will work for your pets.
