True's skin is doing something new and I'm not sure what to do about it.

He finished a 3 week course of 2 different antibiotics to clear up a yeast and bacteria infection caused by allergies. His coat looks good, his ears are clean, and the yeasty odor is gone. His skin is still slightly flaky but is much improved from what it was before.

Now he's getting crusty, scabby things on various parts of his body. He's got a few of these scabs on his lower hind legs and when they fall off the skin is raw looking, but not bleeding.

He also had a boil-like bump which scabbed over on his back that I treated with antibiotic ointment and it is almost gone. He has another, new one on his elbow.

He's currently undergoing desensitizing allergy injections and I'm wondering if maybe this is a normal response to this kind of treatment? He's not breaking out immediately following the injection, like hives, nor does it seem to be hot spots. It's one slow "eruption" after another and it's not something he's had before.

Has anyone seen this kind of thing with allergy injections? Do I need to see the Derm vet again?

Thanks!

Not at the sites, right?

I'd make one more derm vet appointment and get a scraping (that scotch-tape lifty thing) done on one of the eruptions just as the scab is about to fall off.

No, not anywhere near the injection site.

I'll make another appointment for a scraping. Thanks, Connie

My feeling is that it could be toxic eruptions, or whatever you call toxins working out through the skin (a good thing, as long as they are no longer entering the body as well).

However, I would want to check because of the boil episode, which is nothing to fool around with, IMO. Just to make sure that there is no ongoing infection..... or of yeast overgrowth continuing on the skin, which the lifting of cells under the scab will show. (Blood draw would too, but the skin scraping will show other possibilities too.)

Good job, BTW.

As you know, antibiotics don't do to yeast what they do to bacteria, but it sounds like he's doing well.

That examination of skin will also show whether he is still suffering a bit of skin yeast overgrowth.

What you are describing sounds like what happened to my dog. Does the hair come out in tufts/chunks over the eruption? Like in small circular patches one at a time?

If so.. in answer to your question yes I have seen this in reaction to an allergy (NOT allergy injection). My dog had cancer and I stupidly gave her grape seed extract (an antioxidant/anticancer in humans but toxic to dogs). The derm vet said it looked like an allergy. When I stopped giving the extract her skin cleared up.

So I guess it could be a reaction to the allergy shots, which, iirc, are injections of a small amount of the allergen to desensitize the dog. I am not sure if it is normal or not but I would guess his body is reacting to the presence of the allergen. Possibly this is expected with the exposure?

Good question, Angela.

I would think that too except that the lesions would itch like crazy.

Sarah, you didn't mention itching and when you included a boil, I assumed that there was no itching involved. I should have asked.

Sorry to be so late responding.

Angela: no tufts or chunks of hair are coming out. Acutally, the hair on the patch on his back was matted and clumped with scabby stuff. I gently combed it out and applied a topical antibiotic ointment, which seemed to help get rid of it.

Connie: Yes, he's itchy. Much less so than pre-treatment when his coat was greasy and he smelled so terrible but more than when he was taking Temaril-P. Some days are worse than others but, in general, his itching is less than before. He couldn't reach the boil-patch on his back so he wasn't chewing on it. He is licking the crusty/raw patches on his back legs.

Per the Derm vet instructions he is being bathed 2-3 times/week with Relief shampoo and I'm leaving in the Relief conditioner. I'm wiping him down as much as possible but I may need to bathe him more. If I had a walk-in shower he'd be showering with me every day

I spoke with vet and they're sending me Chlorahexidine shampoo, which I'm now to alternate using with Relief. They are also sending more Simplicef, as the vet feels the yeast infection is not entirely gone.

You might want to get a spray bottle of Relief too. Since many products are called "Relief," I'll add that the one I like a lot is made by DVM. I always keep it around.

If the yeast is still hanging on, why Simplicef? Isn't that an antibiotic that has some instances of yeast overgrowth as a side effect? I'd ask about that.

Also, Malaseb and other yeast shampoos might help.

I would want a skin test to find out just what it is.... and I'd want to discuss the Cefpodoxime. I am almost certain that I've read that one of its potential side effects is yeast overgrowth.

I do have DVM Relief spray on-hand and I am using it often on the itchiest spots. The shampoo and conditioner are also DVM products.

I asked about Malaseb at out first appointment and the vet said that for as often as True needs to be bathed Malaseb would be too drying to his skin, which might cause even more itching.

I think he's prescribing Simplicef because that's what True was taking before. He was on it for 21 days. I didn't know it could cause yeast overgrowth...Gads, not the thing we want.
