It turned out that Charlie had popped a few of his sutures and some others were starting to work loose, so they had to sedate him, redo the whole line with staples instead, then wrap him up even more than before and add a new, extra-large e-collar to discourage him from messing with it. He was at the vet all day Friday and got another 24-hour pain shot. This cone was so big that I had to hold his food and water for him. He also REALLY hated it. The blurry pic above is him trying to shake it off.
The other conclusion is that Charlie needs to stay confined until he’s more healed, because he kept trying to jump up on furniture and such (even when I tried to make him some steps!) He needs to stay still and NOT MOVE AROUND so his incision can heal. So Charlie is sentenced to bathroom jail until further notice.
