Our Vet ER is Trusted by Local Pet Families

I have never been treated so good as I was last night. Sammy is my baby and I have had so many losses in the past few years. Everyone at Mason Dixon Animal hospital was extremely warm and very understanding. So glad to know there is a place like this in the area.  I can't thank you all enough for your kindness and attention.

All of you were amazing with Diva today. She has rebounded nicely and has been doing great since I brought her home. You were really thorough with her and calming my daughter down on the phone. So reasonable in price, as well. Not that I want to have another emergency with my pets, but if I do, I definitely know where I'm taking them. Thank you.

Thank you to the all the staff who worked the evening of 6/2 and early morning hours of 6/3. Had to say goodbye to my kitty, Buffy, who was 19. I was lucky to have had such a long-time with her, but it still was gut-wrenching to let her go. It was her time to cross the ? bridge and I honestly couldn’t have asked for more caring, supportive vet team.

Everyone was caring and compassionate. They provided excellent care to our hurt furbaby. It's wonderful that there is now a choice in this area. I believe that the other emergency vet in the area needs the competition. They leave a lot to be desired. Mason Dixon and Dr. Parr were wonderful! Thank you!

They took excellent care of my fur baby Piper. She is starting to bounce back to her old self. Highly recommend!

When my Labrador ingested some cleaning solution, I didn’t know where to go. It was late afternoon on a Sunday and our usual vet was closed. Thankfully, the amazing team at Mason Dixon could see us right away and offered prompt medical help to get Lucy feeling her best again. I cannot thank you enough!
