Sundae and I saw the vet today- he was pleased with how she is coming along, and said I am doing a good job taking care of the wound and keeping it clean. He said most owners are really squeamish about it and don't want to clean it out properly, and that I should have been a vet! LOL! That's one of the things I really like about my vet... at this point he seems to treat me like I know my stuff and is very willing to show me how to do things myself (at this stage, I mix my own meds and he gave me a big bottle of veterinary antiseptic to rinse out the abscess because he said if I'm putting in so much effort to irrigate it, I might as well use the same stuff he uses post-op.) We talked about Zithromax, and he said he has not prescribed it himself in the past, but he will do some research about it and we can see where we are at her next follow-up in 2 weeks' time. If he feels comfortable about it and if we are still expressing pus from the wound at that point, it may be worth a shot. So we'll see where that goes when I go back. In good news, she has gained another couple of ounces and is back at the 2 lb mark, which is great! Her maximum weight has been about 2 lb 9 oz, but since she began having issues with her teeth about 6 months ago, she has been around 2 lb 3 oz on average, so we are inching back to her pre-abscess baseline. The vet also pointed out what a nice piggy she is... he said he gets bit draining some abscesses, but she just squeaked for a minute and then went back to sitting with her front feet on my hand, looking around. Hopefully things will continue to go well for her.
