Bus has either some sort of growth, or a foreign body under/in the skin on his left side. We have been hitting the beach at the park a couple times a week the last couple months, which means traipsing through the brush and along deer trails from the main trail to the beach, which for that reason is rarely occupied and pretty much his favorite place ever. We frequently encounter sticker/thorn bushes, and as he's low to the ground, he gets little scratches/tears from them and other brush along the way. I usually find a couple thorns in each of us (mostly my clothes, but his skin) when we get back to the car, or later that day/the next day.
Anyway, last Monday night, I noticed a little scab on his right side, looks like the normal type from a sticker. Tuesday, I felt something weird on his left side while we were doing his therapy dog visit at the senior center, felt like a sticker with inflamed skin/slight swelling around it- so I pulled it (it was on the side facing away from me, so I didn't see it). It was actually slightly "attached", and from that I figured it might be a scab instead- but it was already off by that point. I left it alone after that, but once we were back in the car, inspected the spot- just a tiny spot where it might have bled, and a little BB sized swelling above/beside that. I gave it a little squeeze to see if it was an abscess (not the first from the same sort of thing), but nothing came out, and not wanting to keep messing with it if it was actually a growth, I left it alone after that. It was slightly red after the manipulation, but that has since resolved, leaving just a little defect in the first layer of skin (maybe where a FB entered?). I noticed that the swelling under the skin seemed to be dark colored at its widest point, and also seemed to be oblong/conical in shape.
Since he goes to work with me every day anyway, I had one of his vets look at it the next day, and she agreed that it's weird, linear in shape, and about 1/2" long. She said just to keep an eye on it for now, and agreed that antibiotics might not be a bad idea, in case it is a FB, so he's been on baytril for the last 4 days, and I think the swelling has reduced somewhat. The dark colored area seems to be smaller and not as dark anymore, and the "mass" has IMO taken on a very stick-like shape, which has me thinking that a FB is most likely at this point. I'll probably wait for her to return Tuesday to see what she thinks about its current state, but was curious whether anyone else has experienced something like this? Did it eventually work its way out through the skin? Or need to be surgically removed? I keep thinking about grass awns, and how they work their way deep into the body (we don't have them here), but at the same time, would rather avoid surgery if possible. He is acting completely normal, and doesn't seem to be remotely bothered by it.
