one of our boys, carlo (1yr 8m) has started self barbering over the last couple of weeks and it’s getting increasingly worse despite xeno 450 treatment which was prescribed by the vet despite no signs of mites. the pictures below are only 2 weeks apart and he’s started to chew at the skin now. he’s going to a specialist thursday but is there anything we can do the deter him from making it worse in the meantime?
