Coronavirus (COVID-19) Information

To the clients of Spartan Animal Hospital,

We wanted to first thank you for your continued understanding and patience as we have all navigated this ever-changing situation.

Beginning July 1st, we will be transitioning back to a more “normal” appointment environment. While our lobby will remain closed to help with social distancing, we are welcoming our clients to return to exam rooms with their pets. We kindly require that you limit your visit inside to one adult with your pet. Please understand that availability of these appointments may be limited due to the addtional time required for cleaning/sanitizing.

In addition, masks will be required for ALL clients entering the clinic.

If you are feeling sick, feverish, or coughing, please reschedule your appointment.

If you prefer to continue with our curbside/drop off appointments, this will remain a welcome option. Technician appointments, medication and food pickup will remain curbside.

When you arrive at the clinic, please call us at (608) 838-6115, and we will provide you with additional details for your visit.

As we make these changes, our priority remains providing our excellent standard of care while minimizing the risk to both our clients and staff. Again, thank you for your continued understanding.

See What Our Clients Have To Say

  • "The staff here is fantastic! They are so kind and understanding and always put my mind at ease. You can tell they love animals and understand new puppy mom worries ;) I'm so glad this is the vet we chose for our puppy! He probably agrees, he likes the treats when he gets his shots. Thanks for everything you do!"
    Anna T. via Facebook
  • "Always a good experience with Dr. Mike. I started coming here with my exotics and eventually brought my other animals in as well. He is absolutely fantastic. I wouldn't want to go anywhere else. They way the staff treats you and talks to you really resonates when you're having issues with your loved ones."
    Jenni S. via Facebook
  • "Dr. Mike was great. Be prepared to stay a while because exams are thorough and some labs can be done on the spot! Doc took the time to explain everything and give us all our options. I was expecting the $ to be much higher considering we had labs & medicine, but it was reasonable."
    Ann G. via Facebook
  • "They are amazing, staff is great, Dr Mike is the best for sure, I wanted to tank them in behalf of my family for their card they mail to us after we had to put our dog to sleep, I definitely recommend Spartan Animal Hospital, I live in Verona and I don't mind to drive to McFarland to have them take care of my pets."
    Felipe R. via Facebook
  • "We get great care from Dr. Mike and all of the staff at Spartan Animal Hospital. They are all genuinely interested in me, and my concerns for my pet's health. They take an interest in each patient and also respond to the owner concerns. We now have our fourth dog. All of the others have lived out their lives in the care of spartan animal hospital. When our last dogs were nearing the end of life, we were able to prepare for the next steps with an informed decision. They were able to provide comfort with knowledge at a venerable time. Thank you."
    Rob R. via Facebook
  • "Dr. Wenninger is fantastic. His level of knowledge and passion for the animals he cares for is beyond what I was expecting--and I had extremely high expectations! I brought 2 of my exotic animals here for examination and it's likely I'll start bringing my cats here too now. Thanks again for helping me help my critters out."
    Laura D. via Facebook
  • "Dr. Mike is truly an amazing doctor! He took such great care of our little turtle named Houdini! I am feeling so relieved after the visit. You can tell Dr. Mike is truly a knowledgeable and caring doctor. I appreciate the time and care he took with our appointment. Thank you again!!"
    Crystal J. via Facebook
  • "Dr.Mike is awesome. He is extremely knowledgeable, very understanding, and kept me up to date on everything. The only person I will bring exotic animal(s) to."
    Brittany L. via Facebook
  • "Dr. Mike really knows what he's doing and is unbelievably kind in doing so. We will be back any time we need a veterinaria"
    Dan D. via Facebook
  • "I was so impressed with everyone at Spartan Animal Hospital! Friendly welcome into the clinic and the first thing everyone did when they walked into the exam room was introduce themselves and shake my hand. For me, that is huge! They understood that my parrot would be stressed and waited to do everything with him at the same time to help keep him calm. Dr, Mike was fantastic, as were the CVTs helping to do the toughest part - holding Oscar without him biting them! Dr. Mike took his time with him, was gentle and very knowledgeable. I actually enjoyed my visit! We will be back for more nail buffs and wing trims! Thanks for making his visit a good experience for us both."
    Nancy L. via Facebook
  • "I only had one occasion, recently, to take my 35 year-old BFF, Groucho, a Congo African Grey, to see Dr. Mike. I was totally impressed with the knowledgeable service, care, and kindness we received, despite the prognosis that Groucho received. The prognosis was not good, heart arrhythmia, and Groucho died of a heart attack just a few days later. It was sudden, which is better than a long drawn-out illness, and I appreciate the time Dr. Mike and his assistant, Amber, gave us. To receive a sympathy card was the final good touch. For someone who has had companion parrots for over 35 years, I would highly recommend Spartan Animal Hospital to anyone who cares about their winged or four-legged friends."
    Clarence P. C. via Facebook
  • "Dr. Mike is the best. Very knowledgeable when it comes to reptiles and he has a love for them as well. He recently helped me out a lot with a huge snake mite infestation that broke out among my collection and he did everything in his power to make it as inexpensive as possible for me which is beyond amazing for how much this could have been in the long run. This will be he only place I take my reptiles from now on. Thank you!"
    Richie B. via Facebook
