KONG Cloud E-Collar is a comfortable, inflatable e-collar that doesn't interfere with your dog's peripheral vision or their ability to eat and drink. Greats for dogs and cats recovering from surgery or wounds, these collars are washable, scratch and bite-resistance and will not mark up floors or furniture. Available in five sizes. For larger breeds with longer limbs, or breeds in between sizes, always size up. Always monitor your pet to ensure collar is working properly. Some pets may be able to maneuver around any collar.
