Welcome! I am Dr. Altman, a licensed veterinarian and I am happy to answer your questions.
So sorry you both are going through this and are not getting answers to help resolve his issues
My primary concern with his history of IMHA is a condition called vasculitis, CLICK HERE for more information
Do you have an ability to see a veterinary dermatologist in your area? This would be my recommendation, to see someone who specializes in unusual skin issues and can do biopsies (awake with a local anesthetic) and get him started on appropriate treatment
Even though the IMHA has been controlled, often these dogs are more prone to other autoimmune diseases
I personally had a dog that had an autoimmune condition and several years later had another one (went from an immune mediated platelet problem, to an immune mediated skin condition, to an immune mediated red blood cell condition that were spaced 3-5 years apart each) so vasculitis would be my primary concner
Secondarily would be a condition called erythema multiforme, CLICK HERE
Lastly would unfortunately have to be some type of skin cancer such as cutaneous lymphoma or histoplasmosis. All of which can be diagnosed off a skin biopsy so I really do think that is the first step
I don't have any parasitic causes for what you describe though. It can be fungal, bacterial though
Please let me know if this information makes sense, I am going to change formats in hopes you are able to view my responses and ask any additional questions you might have
If you have more questions or if I can help in any other way, please do not hesitate to ask! If you would like to accept my answer, please press RATE OUR CONVERSATION. Bonuses are always welcome (I am not compensated in any other way). Thanks!
If you have additional questions after you rate the question, you are welcome to request me for additional conversations if I am on-line or by beginning your question "Dr. Altman..." or "Dogdoc4u..." and others will leave the questions for me. Good luck to you both!!!
Thank you for your kind responses. We had already sadly considered the 3rd option you came up with as it being cancer of some sort, though these lumps are cropping up on a daily basis, and I hadn't thought cancer would do that, but I suppose if it's gone undiagnosed then it's possible.
I've just tried to do a google search for images relating to the the other two options you suggested, which is more than my current vet had done, and the most likely option seems to be erythema multiforme. Is there any way I could send you a quick photograph that I have, that might help.
Sorry to be a nuisence :(
Thank you so much, and again sorry to be a nuisance. I don't have a photo of the large lump, as he won't keep still for long. But it is about 4 inches across and protrudes about an inch, I believe it is comprised of lots of these other lumps, which are spreading over his body. I will be ringing the new vets at 8.30am in the morning, as he has finished antibiotics now and they have done nothing to help. His constant itching is not helping him.
I hope you can see these two pictures, and thank you again.
This is the biggest one, it's huge! I've been cleaning it down daily to prevent infection, even tried covering it to keep it clean, but the dressing just stuck to it and made it worse. I'm washing bedding constantly to keep that clean as well, and as well as trying to do my best for him, it's embarrassing as it looks like I've just left it alone to get like this :( This is why I wanted another opinion and why I will be taking him to another vet tomorrow, I shouldn't have put my faith in the last one :(
Thank you for your support and kind words, I had actually been preparing myself for that. Whatever happens from here, more than anything I just don't want to feel that he is suffering in any way. He's definitely uncomfortable, and that's not surprising. The lumps seems to be increasing in number daily now, and if it is cancer I would assume that it's aggressive and widespread. I will however see what they say tomorrow, and I will of course let you know what happens.
Thank you for everything :)
Thank you for all your help over the weekend.
Kuro was not well at all this morning, and the only last kind thing I could do was let him go, the very nice lady vet agreed with you last diagnosis, and giving him any kind of treatment would have just prolonged his suffering, and my suffering doesn't matter.
We will have a burial for him later on this afternoon.
Thank you again :)
