Where healing meets heart … and pets are family.

Welcome to our family

The perfect fit for your pet’s care

Choosing a veterinarian is about finding the right fit for your family. Great care comes from four pieces, each shaped to fit the others, and none of them is complete on its own.

Your pet
You
Us
Together
  1. Your pet is the heart of the puzzle Every other piece is shaped around them: who they are, how they live, and what they need to feel their best.
  2. You connect right alongside You bring the daily love, the routines, and the small changes only you would notice. Nobody knows your pet the way you do.
  3. We lock into place with you We bring modern veterinary medicine with old-fashioned caring. Your pet gets conventional and holistic options, explained in plain language and built around everything you’ve shared with us.
  4. Together, the picture is complete When all four pieces connect, you get more than a visit. You get a true partnership that honors the bond you share, from the first appointment through the golden years. Welcome to the family.

What sets us apart

The Countrycare difference

Our mission is simple: to honor and protect the human-animal bond by giving your pet an innovative healthcare experience built around their unique life story. That starts with how we practice medicine; we don’t believe in one-size-fits-all care. Whether it is advanced diagnostics for early disease detection or a gentle, multi-modal plan for senior arthritis, our goal stays the same: to give you the highest quality of time together.

Our mission

  • Two hands gently cradling a tortoise.
  • A Countrycare team member holding a tabby cat against her shoulder.

Care for every age

A lifetime of vitality, every step of the way

Every stage of your pet’s life brings new joys, new milestones, and new healthcare needs. We’re with you through every single one of them. Our goal isn’t just to treat illness, but to maximize your pet’s longevity, vitality, and happiness from their first playful pounces to their golden senior years.

In their words

The hearts we’ve touched

A woman crouching beside her German Shepherd on a wooded path, one arm around the dog.

“I arrived with a bag of pills and not much hope for Fina’s quality of life. Dr. Strickfaden listened, and within weeks my German Shepherd was on the road to recovery.”

“Years ago when all other vets gave up on my older dog Katy, Dr. Strickfaden got her back to agility competition form with acupuncture. I’m a big fan!”

“Countrycare Animal Complex is what I wish for all pets. Your compassion and genuine caring makes all the difference. Duke is a happy dog because of you.”

A Yorkshire terrier looks out over a woman’s shoulder as she holds him.

“Everyone there was great — from making the appointment to the vet tech to our vet. Everyone was super friendly and nice. They took their time. We didn’t feel rushed. We were very happy and grateful to the staff.”

Anne S. · Denmark, WI
A smiling man lies on the grass beside his happy golden retriever.

“Dr. Heintz was so gentle and compassionate with our dog. The vet tech was so kind and understanding with all of the questions that I asked her. They made me feel comfortable with the decisions that we made for Maddie.”
