I did transfer vets during Covid. I've been using a mobile vet for years, her business is picking up, but with a house of mainly younger pets now, I wanted access to a vet who has surgical capabilities and with Deacon eventually needing a neutering, I wanted to start out with one from the get go. I was able to transfer and I am quite happy but I was a well known previous customer due to my pair of piebald doxies - no one forgot about the Hewitt boys! Plus this is the vet who neutered Brodie - at that time they were renting out surgical rooms one day a week at another practice - now they have their own building. They are doing curbside but it's run like a charm the two times we've been. Drive up, text, someone comes right out and if the vet wants to speak to you they come to the car. Pup is returned to the car and a bill is forwarded to email later to be paid through Venmo. It's pretty impressive - sure there are hiccups at times - probably runs smoother this way as they are no chatty customers to deal with and hold stuff up. Even Thursday, in the midst of a snow storm they called and I headed over early since someone cancelled.
