Thor needs your help

This is Claudia, and that is Thor a bundle of fluff and love of 8 years old.

Just like me, Thor suffers with dermatitis and he has Malassezia, which sometimes takes on his ears and sometimes on his skin.

At this time, we cannot clear if it's a seasonal thing, or not. I have changed his food to a hypoallergenic one and told everyone around who loves him and always gives him treatos for being a good boy, to please just pet him and not giving any extra food and it seems to have helped really little.

But his tail now has a bunch of spots with it and it's very uncomfortable to him, he keeps scratching and apparently it hurts a little somehow cause he's yelping from time to time.

The vet gave me some supplements to give for 2 months and help with it, but because they have to be given according to his weight, and he weights almost 40 kg, I need to buy a box a week and I simply cannot afford. I found a pharmacy online where I can get them with a discount, but even with the discount is too much I can handle and the pet insurance doesn't cover for them at all.

I am here to ask for help for me to help Thor be better and start playing with his frens and toys again, without further pain and issues. Thank you.
