Is he vwd cleared, carrier or positive ? I just ask because if he had bad bleeding it could be a result of being vwd positive. As for forming, my males Ares was put in a cup with the edges out able to breathe, this is to reduce chance of infection. He was not posted till edges were completely healed, I recommend you posting them yourself. My female I just got was not put in anything, she gets her stitches out Wednesday and will be posted once the edges are completely healed.
Imo different dogs require different things, Ares was itchy and needed a donut to keep him from ripping the stitches, my female has barely scratched hers. Ares was hand cut, Athena was also hand cut. I used neosporin with lidocaine on Ares to numb his ears, I haven't had to use anything for Athena. Many will recommend not using anything on the ears because it can show the stitching or something, I don't have that with my male, like I said I believe it depends on the dog. You do what you have to I guess. I also would probably take all that get up off and just let them hang till he's healed up, it won't harm any chance of standing, what would harm them standing is not posting for as long as needed.
