His stitches popped open after the vet took our staples at 7 days. The wound won't heal. He has been on meds, use of e-collar, limited to a leash for months. He licks it, but he seems to open it with just activity. At the moment he is feeling good, wants to run, and acting frisky- but the wound refuses to heal. He did have a major infection earlier in the ordeal, but the vet says it was superficial and to just leave the site open. It has been 4 months and it hasn't healed! Sambo had a previous ACL surgery with a different doctor last year and had no trouble. We have spent way over $5,000 trying to help him. Your thoughts????? Are there wound care products we should be trying????
