Teagan's Boo-boo

On Thursday I was petting Teagan's belly, as I do most mornings, when I felt a weird lump. I looked at her belly and didn't see anything out of the ordinary so I figured it was just the scar from when she was spayed at such a young age. On Friday, the lump felt bigger and I started to become concerned. But I'm still unemployed and since Teagan was acting perfectly normal, I decided to ignore it in the hopes that it would go away on its own.
No luck. On Saturday it was bigger still and I considered calling the vet for advice but ultimately didn't. Then on Sunday, as Teagan was getting loaded into the car to head to Minooka, I saw that the lump had changed greatly. It now looked like a big blister or boil.
The trip to Minooka was great and Teagan took a long nap when she got home. When she awoke, I noticed that she was licking herself more than usual. I looked and of course the lump had burst and the sore was all bloody and puss. I cleaned the wound as best I could and bandaged her up.I think she looked like a little sumo wrestler.
First thing this morning we went to see Dr. Katie. Teagan's boo-boo got a thorough cleaning and she was given some antibiotics to prevent it from getting infected. Teagan really wanted to lick her sore so she ended up in one of those Elizabethan collars.
Poor Teagan. It's all fun and games until someone ends up in a cone.
She didn't like that thing one bit. In the movie UP, the dogs refer to it as the "cone of shame". I think that's a fitting name for it since Teagan looked pretty ashamed when she was wearing it.
When we got home, I took the Elizabethan collar off since Teagan didn't seem to know how to walk or lay down with it on. I put her little sumo wrap on again since that seems to do the trick. For the most part she leaves it alone but I'll have to keep watching her all day.
The unfortunate thing is that we still don't know what's wrong with her. We're trying antibiotics first since that's the least invasive thing to do. The vet said it could be a foreign object got under her skin some how, some weird reaction, or something inside her causing the hardness and the boil. I asked if it could be a bee sting because Teagan is a bee hunter. The vet said that yeah, it could be a bad reaction to a sting but we just don't know.
So for now we'll see how the antibiotics work. The good news is that Teagan is acting perfectly normal so it doesn't seem to be causing her any pain. I hope she doesn't end up requiring surgery.
