Does your vet do their own out of hours treatment? Ours used to, but now uses Vets Now. The vet we saw yesterday about Harry's leg was fine, but I'd be happier if they'd had his notes as I think he might have been better with a couple of days of loxicom, which the duty vet couldn't give him because of his kidneys.
I'm not sure if that's a reason to change vets though, as I'm hoping not to be dashing off again in a hurry!
