I posted this on a dog forum too but I wanted to see if maybe someone on here knew what this was. It looks red and irritated, it has yellow pus-like stuff around it (its dried into her fur), it has no odor, it is not causing her pain whatsoever (she's currently laying with that side of her head pressed against my bf's leg and I was petting and rubbing that area before I realized it was there), she doesn't even seem to notice it we can touch and poke and prod that area and she doesn't react, she hasn't been scratching that area either, and there is zero hair loss. In the top picture her fur is pulled back to get a better look at it, in the the bottom picture that's what it looks like. You can't even see it except for the patch of dried up pus but that's only if you look close. I want to see if this is something I can easily treat at home instead of going to the vet since they are very expensive around here (the low-cost clinic here charges $250 for a spay and the animal shelter charges even more). If she needs to go then we can take her but I'll have to use the money I saved up for her spay and I'd rather not do that.
