Start with a personal account. Most of the veterinarians on twitter with whom I engage speak for themselves, not their practice. This gives more freedom to say random, un-veterinary things. If you want to say, “prevent heartworm disease in your pets” in one tweet, then “my dog just did the cutest thing!” then “I got some great sweet corn at the Farmer’s Market today!” no one will say, “Well that’s a weird train of thought for a veterinary professional!” And you do not need to worry that you are representing your business.
But remember that you ARE representing your business. People DO know that you are a vet, and in a few clicks of the mouse, they can find out where you practice, if you have not bragged about it endlessly in your tweets and profile already, which I think you should, by the way.
