“I’m so grateful for Rossmoye ER. My dogs are frequent flyers here, and thankfully each of their visits have been for less serious issues. Knowing rossmoyne is 10 minutes away, I never hesitate to pile my mischievous furbabes in the car and take them to get checked out. I always think to myself “well, it’s probably nothing...but what if it is serious and I did nothing to help them?” I hope our visits to Rossmoyne are always for my peace of mind. But I know that regardless of the severity or reasons for our visits, my pups will always get great care here. Thank you for all that you do!”
