My girl had a chunk of skin the size of a fist gone from her side/hip area, it healed up completely in 2 months without stitches, I dident want to put triple antibiotic ointment on it everyday because she would always end up getting it dirt and I would have to clean it. I ket it dry up and it turned into kindove leathery, it was closed up about half way in a month and it was leathery and brownish so the others wouldn't pack it. Dont know if it was the best thing to do but it saved me alot of time, I also dident want to keep disturbing the wound, I probably made it take 2-3 weeks longer to heal because I was using hydrogen peroxide to clean it for 2 weeks before I was told it would make the wound take longer to heal. The neighbors dog got out again today, I was fishing about an hour away when the owners texted us. Luckily some of our very nice neighbors came over to watch the chickens for 30 min before my sister got home to put them away. I will not trust them to move or keep their dogs in so now I'm going to invest in an electric fence. Maybe make them an offer, they also pay for you to get an electric fence and they dont have to get rid of the dogs, they still have to pay for chickens but they can keep their dogs. Dont go super expensive mabey just $100 or so, then it will also be good for coyotes, dogs, foxes etc. This might not work for you or you might just want the dogs gone just an idea.
