Unfortunely I think I would look for a back up just for your comfort. I would use the old guy for routeine stuff(ashot, check ups) but have another one for other stuff . I had to makre this same desison with a vet who I even worked for, the younger associte vet got him from seeing patients and work on his passion, birds of prey. (and that was another whole nother story finding eagles in my dog kennels in mornings )
