our Duke has severe allergies.. we gave up on the vet and took him to a dermatologist.. he ended up being allergic to wool. it didn't stop there. he had swollen paws, loss of hair, ripped open wounds etc.
we did put him on steriods ( low dose ) for a while , I did it so he could have a better quality of life.. we eventually weaned him off and now he takes Atopica which is expensive ( there is also a generic form) we are switching him over to.. and he is doing great. Duke takes two Zrtec every day.
Also we had great success with his coat switching to Nature's Variety Instinct. we give the canned wet and dry duck formula.
We were told when a dog has skin allergies the less you bath them the better. Don't laugh we bath Duke maybe 4 times a year.
I am happy to report after a long journey his coat looks great, his bloodwork is good and no more wounds.
Good Luck to you. its so hard when they are uncomfortable.
Karen and Duke
