Super glue works great. The key to it is to keep all the edges together if they top part comes together but underneath doesn't you will end up with a fissure under the healed part ( void area ). it will keep reopening. Also if you get super glue in the wound it will keep it from healing. We use the same stuff in the ED but only for wounds that wont have pressure on them ( face, arms, legs ) The best thing that works is a stapler ( suture type ). It will hold everything together and so forth. Remember that sutures are used for a couple of reasons --decrease the healing time -- decrease the chance of infection sometimes -- looks better no scar.
here is what I would do. clean the area out intially ( once ) with good ole peroxide. Then clean vigoursly with soap and water then rinse. Don't try and close the wound just put some gauze pads ( 2 x 2 ) then wrap with coban ( self adhering bandage ) don't cut of circulation. Then cover the foot with a sock, tape that so it stays on. Clean it twice a day with soap and water only ( peroxide will keep it from healing--it removes tissue that is growing ). The wound will eventually start healing from lower to the top ( regranulating ) Watch for infection :cool: If you have any problems see your vet.
Emt Gel is a colagen base product we use something similar on people. It will actually bond to the wound and keep infection down. You still have to keep clean it first, then apply the gel to the cut ( into the cut ) then cover. Keep him off of it as much as possible for the day. You should be able to hunt with him by this weekend.
As far as cauterize-- I wouldn't. that will stop the bleeding but impedes the healing process.
Or take to a vet.
