A veterinary restraint collar, such as for a cat or dog, comprising one or more concentric rings of soft, flexible and non-resilient material sewn together on their inner and outer margins with binding and a drawstring passage for an elasticized drawstring on the inner margin to secure the collar around the animals neck. Numerous sizes provide a flexible barrier restricting the animals ability to reach treatment areas of its body with its mouth. Different materials are used for different sizes to establish the effectiveness of the collar and to provide a comfortable experience for the animal. The improvement of replacing one panel of the collar with a post-treatment instructions panel, sewn into the collar, provides veterinary and other animal professionals the means to assure the well-being of the animal through these written instructions.
