Expert care for older pets & pets with serious illness.

"You matter because you are you, and you matter to the end of your life."
Dame Cicely Saunders, founder of Modern Hospice

Our mission is to support older animals and their humans with excellent care, love & understanding.  It is also our goal to improve the availability and understanding of veterinary palliative medicine, including longevity support, palliative care, hospice care, and end of life services.
We work exclusively with older pets and
pets with serious illness conditions in order to focus on their unique needs.  

We will communicate with and work together with your primary care veterinarian and other specialists in order to provide excellent care for your pet.

All of our care is mobile.  We are dedicated to providing gentle and compassionate care in the comfort of your home.  We do not have a clinic location where we see patients.  
Because of the unique nature of our clinic, we do not offer vaccinations, radiographic imaging, or surgical/dental services.  We will, however, help to arrange these services if needed.

Our People & Pets

A Note from Dr. Cook

Protecting and supporting the bond we have with our pets is incredibly important.

Just as our animal companions rely on us to love them and provide for them, we too revel in the unconditional love and joy that they bring into our lives.  

With clear communication, an integrative & holistic approach to medical and comfort care, and the knowledge that every animal is an individual, we can provide excellent health care and honor the very special bond we have with our pets.

Dr. Cook's dog

Dr. Cook adopted McGhee when he was about 6 months old in June of 2017. McGhee has come a long way with managing his separation anxiety, but still doesn't really want any alone time. He is loving, cuddly, boisterous, and a true clown. 

Dr. Cook's dog

Dr. Cook adopted Barry from One Tail at a Time in March of 2021 at the age of ~15 years old.  He is a super sweet miniature poodle who loves hugs and belly rubs. He has a number of special needs including congestive heart failure, kidney failure, blindness, urinary incontinence, and degenerative joint disease. That being said, Barry lives every day to the fullest and is feeling great!

Dr. Cook's dog

Dr. Cook also adopted Pogo​ in March of 2021 from One Tail at a Time at the age of ~12-15 years old.  He is a very proud little Chihuahua/Rat Terrier mix who has a lot of rules, but also a lot of personality. He's slowly finding his way and establishing his empire and list of subjects.
