★★★★★ Great experience. Experienced and friendly staff 🙂Raymond M.Raymond M. ★★★★★ My experience at Gardner Animal /Boarding was very nice and friendly . They took great care of my cat Oscar while he was staying there. They treated Oscar as if it were their own cat,Kaleb A.Kaleb A. ★★★★★ We have a difficult situation between our dogs and Gardner Animal Hospital is very capable of handling it. Most facilities we have used have not wanted to deal with our issues, but GAH has bent over backwards to help us. The take good care of our dogs and we do not stress over leaving them in the boarding and dogie-day-camp. They are also working with technology to provide more to their customers. I love that I can log into their website and get previous information on my dog's health. I hear there is a web-cam coming soon so owners can peek in on their pets at play. Both the humans and dogs in our household LOVE Gardner Animal Hospital....update... our girls have since crossed rainbow bridge. When the time came, everone at GAH was so sympathetic and wonderful. We adopted 2 pups and take them to GAH. Dr.Mertz and her team are wonderful. They caught an obstruction in our terrier's intestine that was life threatening. We were able to get him to a surgeon in time for a positive outcome. They also caught a spine issues that could have paralyzed our terrier, but again we were able to get him to a surgeon in time for a wonderful outcome. Dr. Mertz hires top-notch staff that are knowledgeable and caring.Julie & M.Julie & M. ★★★★★ Honest DoctorVADIM S.VADIM S. ★★★★★ I took my very nervous cat in to see the very kind and patient doctors after he got into a scuffle with his sister and had a scratch on his eye.

Always take such good care!Kevin K.Kevin K. ★★★★★ I have so many wonderful things to say about Gardner Animal Hospital - specially their boarding, doggie daycare, and training options! They have specials during the week for doggie daycare and our youngest pup out of four LOVES all staff and gets so excited when he gets into the car and knows he’s in his way, Sherrie is the best! We also tried out the training with Lacy and let me tell you, our dog has changed significantly since he started! Lacy is magical, I don’t know a better word to describe how much of an impact she has made on our family. I was 9 months pregnant and worried I would go into labor over Memorial Day when the boarding was full and daycare was closed. Lacy put my mind at ease and told us she could pick up our puppy and make sure he is taken care of if I did have to go in unexpectedly. She has successfully trained our pup not to jump up on people, how to handle his excitement, listen to commands, and more. We didn’t have a yard until recently and Lacy helped train our pup to walk on a leash better so I could walk him while pregnant without any worries. Lacy has seriously been a godsend for my family and for that we are dedicated to her and Gardner animal hospital! Bonus is she sends photos of our pup when he visits and texts then to me! I always smile no matter what, plus I know they are in great hands!Amber M.Amber M. ★★★★★ They are absolutely the best!TamiaTamia ★★★★★ Dr Hunter Like recently joined the practice - he had performed a surgery on our dog when he was with another veterinary practice in Overland Park. He is excellent - awesome veterinarian and skilled surgeon. When our dog needed another procedure we drove to Gardner to have him perform it.Tim M.Tim M. ★★★★★ I can not say enough great things about the Staff and Dr.s at the Animal Hospital and Dogs Days Inn. They love our fur babies as much as my family does. My dogs go to daycare at least three days a week and I feel like the staff is part of my family now. I could not have asked for a better group of people to make me feel like our fur babies are always taken care of!!!Carey M.Carey M. ★★★★★ Patient with our troublemaker dogs and always friendly. We've been with them for a while and they've always taken good care of our pets. Despite them always needing to get shots, have their nails trimmed, and - most terrifying of all - stand still on a scale for a few seconds, our dogs love the employees and enjoy their visits here.WillowWillow ★★★★★ Dr. Mertz has treated our fur babies for over 35 years. She and her staff along with Dr. Smith, are compassionate, caring and dedicated to their patients. I will not go anywhere else.Kay G.Kay G. ★★★★★ Dr. Mertz is a fantastic vet.
