I have not been impressed with Fitchburg Vet.  We have had our dog since he was a puppy, and we know him very well.  He has always had a sensitive stomach to food, but we knew he wasn't sick because he was acting just like himself.  We kept asking the vets about it, and they told us he was sick and needed a fecal, even though his last 2 were both negative.  I finally got the best advice from Pet Supermarket (best pet store in town in my opinion) and they told us about limited ingredient and grain free food.  within 24 hours his poop was normal again.  The vets wouldn't even listen to me, and just kept telling me he was sick.  I was really disappointed that I had to go to a pet store to get advice that the vet should have known.
