I adore Dilworth Animal Hospital. Both my cats come here and they'll see reptiles should my snake ever need a vet visit. The entire staff is professional, friendly, and in love with animals. They also all care about their customers and try and make each visit as pleasant as possible. When my older cat, Whiskey, had a bladder infection that wasn't cleared up by a round of antibiotics we had to make a second appointment to see what the problem was. Dr. Wheelock was wonderful, he helped us pinpoint potential causes of the bladder infection and prescribed an additional round of antibiotics and pain killers. We only had to pay for the medicine for the followup visit, rather than a full visit charge! Even better, after having discussed the infection, my boyfriend and I concluded that Whiskey's stress over a recent change in food (from Science Diet to Purina One Beyond) had likely triggered the infection in the first place. Whiskey is now all better, and we didn't have to break the bank to take her on multiple vet visits in a short span of time. I highly, highly recommend Dilworth Animal Hospital to anyone in the Charlotte area who wants the best for their pets.
