  • "To the Staff & Doctors of Middletown Animal Hospital,

    We would like to thank you for all the years of care you gave our beautiful "Suzy" the rabbit. With your help Suzy defied sickness so many times over the years that we thought nothing could stop her. We appreciate all the wonderful time we had with her. A special thanks to Dr. Holtz because Suzy really liked her. She was funny about people so Dr. Holtz made the "Suzy A List". Suzy was the sweetest, smartest and funniest rabbit. Her daddy is especially devastated with her passing. They were pals and she followed him around the house. She sat at his feet wherever he was and layed dow with him in front of the TV giving him kisses. Suzy had him wrapped around her bunny finger. Thank you again for taking care of our little girl over the years."
    Carolyn Carroll & Lee Company Clearlake, CA
  • "Our five-year-old cat Kaylee has vomited about once a day for the past month. Dr. Smith quickly diagnosed the problem and Kaylee hasn't vomited for the last two weeks.

    In addition, Dr. Smith and staff have cared for 11 of our animals over the past 16 years. They are a knowledgeable, courteous and highly professional group and we are fortunate to have them in this rural area. We have had animals with cancer, kidney failure, eye damage, and everything else imaginable and Dr. Smith and staff have always had the knowledge to handle it.

    We are extremely thankful for the work Middletown Animal Hospital's staff has done over the years."
    Don Krieg Lower Lake, CA
  • "Dear MAH Staff,
    I can't express enough how much I appreciate the care & understanding that my pets & I get from the staff. When I was there last I was talking to another person there and they said the same thing but she had been coming here for over 15 years and had always received great care so that reinforced the feelings I already had about Middletown Animal Hospital. I'm grateful that my pets have great care in a small community!!"
