  • "I just want to say how great everyone is at A R Animal Hospital. Dr. Sidhu always takes the time to explain any issues that our pets may have and gives us alternatives on how to help them get well. As a result, we have three healthy and happy pets. Kobe, Zoe, and Buddy want to thank the staff for taking good care of them when they visit. We would recommend A R Animal Hospital and Dr. Sidhu to anyone who wants to give their animals the best of care. Thank you!"
