I would not be without this first-aid gel ointment. I have used it many many times and can tell you your dog’s cuts will heal so much faster with this stuff. I will tell you it smells gross but worth using because it works so well. I have not talked to another dog owner who has not felt the same way after using the product. The reason this works well is because of the Patented hydrolysate of collagen provides fast healing of all types of wounds. Reduces bleeding and pain as well as reducing chance of infection. Collagen formula provides the scaffolding for new cell growth and prevents scarring. Now you can get it in the spray form or the usual gel in a tube.
