Heyo fellow dog enthusiasts!

We have a 6 year old wire-haired dachshund. Male, generally in good health ( he suffers under a heart-disease though which is being monitored by the vet ).

He recently (~1 month ago) started to get injuries / wounds on random patches of his body. The first time we took him to the vet, they were not sure and instructed us to bathe him with medicinal shampoo and put a special lotion on the wounds.

Since it didn't improve, we took him to the vet again and they determined that the wounds were self-inflicted from scratching and biting due to him experiencing itches, likely caused by allergies. ( We did notice him scratching alot, but didn't immideatly think that it was causing wounds )

About a month ago, we bought 2 brand-new, discounted sofas. They are a mix of real leather and fake leather, and come to think of it smelled quite "chemical" when we first got them ( but the smell disappeared by now ).

As that was the only change in the dog's lifestyle, and the problems have been occuring since, the vet ( and we ) think that the dog is allergic to something related to the sofa. We have been keeping blankets on the sofas, but that doesn't seem to help.

The vet was unable to offer any advice besides keeping the dog off the sofa and continuing the treatment, but I don't see that as a long-term solution as the dog is quite attached to us and well..when we sit on the sofa, he wants to be there with us.

Does anyone know if there is a way to solve this aside from getting rid of the sofas ? Maybe some treatment, or special cleaning or something we could do ?

I can post more information on the sofa if needed.
