These sores appeared over a month.
Yes, I have consulted a vet who said they were urine burns which I thought could be the reasons cause his bed is wet every night as he has difficulty getting up. He recommended calmosestine ointment which I have not been able to get from the local pharmacy.
He initially recommended Triderm which is what I am applying now. However sores keep popping up in different parts of his body.
I have read up on pemphigus. Gordo's sores do not itch (he does not scratch) and are not painful (he does not complain when we clean them) They don't scale either. Some swell and others are flat but increase in diameter. The swollen ones ooze blood and the flat ones seem to have a clear fluid appear on the surface.
I read somewhere that using Betadine makes it cure longer so I have stopped using that and hydrogen peroxide to clean it.
Ok will have lab check on sores and will try the Betadine rinse.
If I recall correctly, Manuka honey is from New Zealand and is quite pricey but will give it a try.
Many thanks for your suggestion and will get back to you with results from lab.
