A safe and comfortable support for the neck of dogs and cats. It will also restrict movement of the head, thereby protecting other parts of the body from self-inflicted trauma. The foam collar is made from an ultralight, dense and rigid closed-cell foam. The collar is black, with both sides being an easily cleaned “skin.” Application of the foam collar is simple. It is wrapped around the neck and held in place with 1 or 2 pieces of standard adhesive tape. It has no sharp edges, and the ends can be trimmed to an exact custom fit. Various widths are available to accommodate most dogs and cats. To size for proper fit, measure from just behind the ear to the top bony portion of the shoulder.
