  • "Dear Valley Animal Hospital,

    I am so thankful for Dr. Halverson and the staff at Valley Animal Hospital. My two babies (Dashchunds) were diagnosed and treated for pancreatitis last week. It is because of you that I still have my precious dogs! I will always remember the kindness and understanding I was given during a very difficult time. I have no doubt my babies were given the absolute best care! I want you to know it meant the world to me and I'm sincerely grateful.

    Thank you ALL so much!"

Further more we have never received a follow-up call from a veterinarian - ever. We feel confident leaving Koda in you care while going on vacation in a few weeks."
