Licking Wounds Question

On Saturday morning I got Twix out and he had a large patch on the back of his neck (50p sized) that was red raw, hairless and a little bloody.

I took him to the vet who said he had done it to hinself as he probably has mites. We had already started him on a course of mite injections 2 weeks ago as his fur was patchy but it's obviously gotten worse!!

Anyway I've got ointment to put on it and some tee tree cream, but how do I stop him from making it worse? He's still licking it like mad and I terid to put a bandage on him which lasted all of 2 hours before i tugged it off!!

I just don't want himto make himself sore

I will probabley get disagreed with a lot, but how about a collar? :? Xx

I was thinking of that....may have to take him back to the vet becaue he's being a little horror!!!
