His medical records would show history of multiple foreign body surgeries so Huck felt living at a vet clinic would really benefit his well being.

Both my cats love the service here. Never want to leave even after shots. Ladies at the front desk are always friendly. Vets are great. Highly recommend.

Dr. Skime and Krissy are fantastic! My 6 month old golden retriever ingested sugar free gum and was in pretty serious condition when I brought her in after hours. They worked so hard to bring her back to us:-). Our whole family thanks you for all you do (and Miss Lena too!)!

-Kerry W.

Our Sophie, a new German Shepherd rescue, loves Dr. Mitzelfeldt and staff! They were very kind and welcoming, helping us enter and leave the office without coming into contact with other pets, which helped Sophie stay calm and focused. Thank you for the wonderful care.

-Nancy D.

We've been going to La Crosse Vet Clinic for many years. They have been excellent! I commend them for being very understanding, kind and professional during difficult times. Five stars in our book!

-Dee M.
