2 pics- a close up of what looks like the bite, and a picture of the rash on the surrounding area.
Presented as a hard, skin colored bump that she scratched constantly. Figured it was just a bug bite. Gave her Benadryl for the itching and she boarded at the vet (*I was in a different city for two months and could not go to me regular vet*) for the weekend. They did a scrape and said there was nothing wrong, just a bug bite. Couple weeks later she started scratching again. Back home and I took her to my regular vet who prescribed antibiotics and steroids because now it is a much larger, scabby rash. 5 days of medication later the rash cleared up great to reveal two very obvious black dots on the original hard lump (now a mushy spot, assuming abscess that the antibiotics are helping). So of course now I think it's been a spider bite all along!
Experience anyone? Treatment? More steroids or back to Benadryl? Does it need to be drained? I called my vet, waiting for her to call back.

What most people thing are spider bites are often the result of some other insect, or skin issues. I mean imagine the size of the spider who'd have fangs that wide apart! Also most spider fangs aren't strong enough to break skin.
Think of the size of the average spider you find in your house. Keep in mind that those two appendages in front of the spider are actually pedipalps, not fangs. Their fangs are closer together than their cephalothorax (head) is wide. Unless you have some gnarly spiders, your eye probably wouldn't be able to distinguish the points. The dots could be blocked pores that resulted from the swelling/abscess.

Saw the other vet in our practice today. He was quite puzzled. Said bacterial infection should have gotten better by now with antibiotics and steroids. Doesn't look textbook fungal, but maybe? Trying an antifungal topical cream and following up in 10 days unless it gets worse before then. He does think it probably started with some sort of bug bite or sting. We looked at pictures in his book of rashes and it seemed most similar to a rash caused from toxins (drug or venom). But it's obviously got something more than that going on now.
If it doesn't get better he said he wants to do a skin biopsy. Might have to remove the whole area. Said maybe mast cell involvement or cutaneous Histiocytomas or who knows!
It doesn't look like the growth my dog had, and hers wasn't itchy but I would definitely do a skin biopsy. Her growth turned out to be a mast cell tumor and we had been told it was a spider bite or a cyst just a year ago. Just do it and be sure. They can look like almost anything. Good luck.
Hmmm. Not sure how much it will cost. It seems like every time we go to the vet it costs a small fortune. The pathology report on the tumor was $155 just itself. I would think a simple skin biopsy would would be less than that. If it seems to be responding to your current treatment, I wouldn't think watching it a bit more would hurt. You can always do a biopsy if it doesn't clear up in a few weeks.
I know this is originally about a dog, but when I got bit by some huge tarantula-like spider in the barn, I looked exactly like that. While it wasn't poisonous, it did a number on my finger. I ended up having to have it lanced a month after the initial bite. It bothered for probably a good three months before it finally started getting better. I don't know if that helps, but my finger looked exactly like the picture of your dog....
Pictureonemore- did you do any treatment other than time and the lancing?
I think it's too small to be a snake. We definitely have a lot of spiders around the house and barn of all shapes and sizes. Vet said give the Panalog 7-10 days, but bring her in if I think it looks any worse. Probably just going to go ahead and take her in Monday.
It waxes and wanes in severity. She's been pretty good about not scratching today, hopefully that's a good sign. This is spoiling her something terrible. She sits by the kitchen counter after she eats her dog food and waits for her Benadryl in a spoonful of peanut butter .
My horse's vet looked at it today and was like "that's obviously not any kind of cancer. What'd the culture and cytology come back as?" ...long silence.... "well why didn't they do that?"
Said he'd call one of his buddies for me to look at her today, but I think I'll give it through the weekend and take the pup to horse's vet's clinic Monday. He has a large & small animal practice with his wife and he's my favorite vet ever.
I was on oral antibiotics for 10 days and had to get another tetanus shot. Apparently spiders can carry that, so they gave me a booster. Before I had it lanced, it got very hard, red, and more swollen than it already was. Total grossness came out of my finger...to this day my left middle finger is noticeably larger than my right. I would encourage at least a culture from your vet. That should at least provide some clue as to the goings on. I hope this helps!
