- I dissent.
Not if the dose isn't correct (which I can't really tell from the info you gave). Sometimes even if the amount used is correct, a second round of Ivermectin is needed in tougher cases. I still think you'd be better off buying Ivermectin yourself and dosing it according to the information here. I'm not convinced that this isn't mites, even with a 'negative' finding. It could simply mean that the particular sample of hair taken didn't contain any of the parasites.
Are there any signs of ringworm or other fungal infection on his skin? -- you'd likely see scaling, crustiness, etc.
I wonder if an anti-itch spray (carefully applied) might help for that spot. I believe there is one for humans.
It's puzzling for sure. His Ivermectin is confusing the way they have it on the paperwork. After looking it over carefully, it's 10 mg/ml and they gave me 5 ml of it from the 50ml bottle they have in their pharmacy. See what I mean? I'm supposed to give him .16ml every Friday for 4 weeks. He's gotten 3 of the 4 doses. Using the dose calculator, it looks like he's getting the right dose.
As far as his fleece bedding, I had been using Tide with Downy to wash the blankets. I was washing them twice; once with the detergent and the second time without it to get any residue out. I was also using the extra rinse both washes and drying the without fabric softener. None of the other pigs ever had any itching. When BJ came up itchy, I stopped using detergent. The last 2 times I changed his bedding, he got blankets washed without the soap. He's getting his third detergent free bedding change today.
The only thing I haven't addressed is the possibility that he's allergic to the mountain meadow/ timothy hay mixture I'm giving him. The humane society gives their hay eaters orchard hay they get from one of the feed stores. They also get hay donations from several sources, so it's virtually impossible to pin down exactly what types he's been exposed to. I'm inclined to think that hay isn't the issue since Benadryl doesn't help as much as it should. I'm not totally dismissing it either.
So I'm back to the topical treatment options. What product do you guys recommend? While I'm on the subject, I have got to get some coconut oil for his grease gland. Is there a certain one I should use? Can I treat the gland with that at the same time I'm treating with the topical Ivermectin or would they clash?

Still not sure I understand the dose your vet recommended. For me, the math doesn't come up with a 0.16 dose for 10mg/ml of Ivermectin on a 1.56kg guinea pig.
When applied topically, ivermectin is usually put behind the ears, though it could be put anywhere. For farm animals, it is often poured down their spine, and therefore called a "pour-on". If you are giving more doses, you could actually put one of the drops on the itchy area (best if there are no open sores).

I did find this one on Ebay too. https://www.ebay.com.au/itm/Dermacare-Aloveen-Oatmeal-Shampo ... txZAvjIgydhA
Dermacare Aloveen Oatmeal shampoo. With the Johnson one it worked well on my girls. Vet said puppy and kitten ones are especially made for delicate skin. Hope BJ starts to feel better really soon.
I can wash him with it twice a week, so I'll wait a day and bathe him again on Thursday. In the meantime, I started his baytril, probiotic and vitamin c. Standard drill here with twice a day doses followed by the probiotic and vitamin c about an hour after. Well, here we go again. Not my favorite part of guinea pig ownership, but I'm going in with the same resolve I had with Scruffy. If you want me to, I'll start a medical thread, but I'd rather just post everything here if that's ok. Just let me know.
The only prescriptions BJ has gotten were Ivermectin, OTC Benadryl, baytril and the Pramoxine shampoo. None of the hair and skin samples showed positive for any parasites. I'm just hoping there's not a serious issue causing this.
The itching was better today but not totally gone. He has his good days and his bad ones with the itch, so until I see several days; as in 5 or more itch free, I'm not going to do back flips. I also gave him the probiotic in a thin solution of water and a sprinkle of critical care. He really hates that syringe and fights it the whole time. My experience with Scruffy and use of a syringe is coming in very handy.
This is the only spot where he itches and the hair looks like its getting thin. I just thoroughly upset him so I'm letting him settle down and then I'll try getting one of the skin underneath and of his grease gland. It was pretty crusty, but the coconut oil is helping already. Hey, I wonder if that could be causing the itch. The spot is pretty close to it.
