I wish I could rate this clinic more than 5 stars. I took my dog there a few weeks ago on death's door. I went to 5 other clinics in the area all of which gave me VERY expensive estimates with little chance of survival. I went to Callaghan Rd Animal Hospital and met their two vets who both were so personable and kind and truly cared about my dog. Not only were they very positive about saving my dog's life but they were SO affordable, almost 1/3 of what other clinics were charging. Thanks to Dr Evans and Dr Guevara my dog is alive today and my bank account still intact. It is a family owned business with two adorable boys who roam the clinic. Their staff is amazing and they treat you like family. I would recommend this clinic to anyone in the San Antonio area.
