I took Gizmo to the vets yesterday as I noticed he was a bit itchy around the top of his ears and the skin looked a bit scurfy. The vet looked at him and said it was just dandruff like humans get. I wasn't convinced because the skin also looked a little inflamed. The vet went off to get some hibiscrub and told me to dilute it and apply it for a week. But before he came back in with it, I noticed a flea on Gizmo's ear and called the vet back quickly. He then give him a dose of xeno 450. We couldn't find any more fleas but I'm aware that if he has one, there is more. I feel terrible about this as he is groomed every evening but I have not noticed any fleas and its really making me feel like an irresponsible owner. I was using the beapher spot on but stopped once winter arrived as I thought it best to give him a break from these chemicals. I asked the vet if I should use the xeno every month and he said it might be a good idea but I've been reading online that its best to only dose rabbits if they actually have a problem. I'm really keen to keep using something to keep parasites at bay as I feel so awful about this. Is it safe to keep using it? Is the Advantage spot on better? I disinfect his hutch with virkon S, is this good enough? He goes in the garden for hours every day and I've heard they can get fleas off the ground. Would it be best to use rearguard as well? Although I'm not that keen on chemicals, I can't stand the thought of parasites on my bunny. It's made me feel like such a bad mum.
