The Comfy Cone Extender Panel is specially made to extend the length of the X-Large Comfy Cone Collar for Dogs & Cats or the Medium-Extra Long Comfy Cone Collar for Dogs & Cats—the only soft, cone-shaped e-collar with removable stays for dogs and cats, and an extra long cone to ensure pets with longer snouts can’t reach wounds and irritations. Comfy Cone Extender Panel adds two inches to the neck, ideal for Mastiffs, Rottweilers, and other dogs with thick necks.
