IsoPet® Treatment for Dogs
According to the Veterinary Cancer Society, cancer is the leading cause of death for 47% of dogs, especially dogs over the age of ten. Some of the most common solid tumor types found in dogs include mast cell tumors, soft tissue sarcomas, squamous cell carcinomas, hemangiosarcomas, melanomas — all of which IsoPet® has successfully treated. IsoPet® delivers targeted radiation to cancerous tumors while minimizing risk to surrounding healthy tissue, resulting in a safer and more effective procedure for your dog.
IsoPet® Treatment for Cats
Cancer is one of the most frequently diagnosed diseases in older cats, with solid tumors such as fibrosarcomas, squamous cell carcinomas, and soft tissue sarcomas among the most common. These cancers can be aggressive and challenging to treat with surgery alone. IsoPet® offers a minimally invasive alternative — delivering targeted radiation directly to the tumor while sparing nearby healthy tissue. This precise therapy provides a safer and more effective option for feline patients, improving comfort and quality of life.
IsoPet® Treatment for Horses
Skin tumors are among the most common forms of cancer in horses, including equine sarcoids, squamous cell carcinomas, and melanomas. These tumors can cause significant discomfort and may interfere with tack, performance, or appearance. IsoPet® delivers localized radiation that targets the tumor site with minimal side effects, offering horse owners and veterinarians a powerful treatment option that preserves the animal’s comfort and long-term well-being.
IsoPet® Treatment for Exotics
Exotic species such as rabbits, birds, reptiles, and small mammals are increasingly diagnosed with tumors as veterinary imaging and diagnostics advance. Traditional surgery or systemic treatments can pose high risks for these delicate patients. IsoPet® provides a precise, localized form of radiation therapy that can be adapted for a wide variety of species, allowing veterinarians to treat tumors effectively while minimizing stress and preserving the animal’s health and quality of life.
A Safer Cancer Treatment for Small and Large Animals
Extending the lives of animals through our certified IsoPet® regional veterinarian clinics across the USA.
Safe & Effective
IsoPet® delivers more than 90% of its therapeutic radiation within 10 days of a single treatment. Other therapies may require six weeks or more to deliver the full course.
Same-Day Procedure
IsoPet® therapy is performed as an out-patient procedure and your pet may return home without subsequent concern for radiation exposure to your pet or family.
Minimal Side Effects
IsoPet® therapy is administered directly into the tumor without harm to the surrounding tissues or organs. Your pet should not feel harmful side effects of treatment.
How IsoPet® Works
Parallel Needle Injections
IsoPet® is continuously injected into the tumor in a grid pattern to ensure that the treatment is spread equally throughout the tumor — minimizing the dose to adjacent healthy tissues.
IsoPet® treatment is in collaboration with distinguished veterinary research centers across the United States.
“We have compelling evidence that IsoPet® will kill the primary tumors in a single treatment with a high therapeutic dose of Precision Radionuclide Therapy™”
Dr. Michael Korenko, Sc.D. CEO of Vivos Inc.
Our Pet Patients Helped by IsoPet®
Jazper – canine
“Jazper has really been doing wonderful! You wouldn’t even really be able to tell he once had a massive soft tissue sarcoma on his elbow/leg area. The mass is COMPLETELY gone! When we touch that area it is pretty much completely flat which is an insane miracle compared to how that spot started out with the huge sarcoma. We are so very thankful that we found IsoPet and Dr. Krimins. We drove 12.5 hours each way twice. Thank you all so much again for treating our Jazper and saving his life.”
– Kristen Grochowski, pet parent

Brew – 11 year old canine
““Great success story. Brew and I thank you for his return to a more normal life.”
– Brew’s Pet Parent

Francis – 12 year old canine
“I am beyond THRILLED”
– Francis’s pet mom

– Dr. Rebeca Krimins, DVM Johns Hopkins Hospital
Cancer Type: Carcinoma – left front leg, 3 weeks rapid growth before a single IsoPet® treatment in 2022 at Johns Hopkins Hospital.
Oliver – 12 year old feline
Oliver had a previous tumor and a prior traditional cancer treatment left him with an amputated left hind leg to attempt to remove aggressive tumor. When another tumor surfaced on his other leg his pet parents contacted Johns Hopkins Hospital and performed IsoPet® Precision Radionuclide Therapy™ in 2022.
Cancer Type: sarcoma
The sarcoma in his leg, grew rapidly in less than 2 months and was successfully treated with one IsoPet® treatment.
Picture was taken post surgery while Oliver was resting at home and according to his pet parents he was very happy!
Drake – 11 year old feline
After several attempts and chemotherapy, Drakes pet parent travelled from Alaska to Vista Veterinary Hospital in Kennewick, WA.
Cancer Type: Spindle Cell Sarcoma – right side of the face by the nose
The owner is a Veterinarian and at 17 days following the IsoPet® treatment reported:
“There is a continuing decrease in the neoplastic mass. I suspect that some of the residual swelling is inflammatory in nature. The skin is intact, no ulceration or necrosis. Therapy was effective.”
– Drake’s pet parent and veterinarian
Annie – 10 year old canine
“She is doing really well, totally back how she was before we found the tumor. The tumor is fully gone now and the hair in that area has grown back, we didn’t see any side effects from the treatment at all. She can run and walk a few miles each day, eat well and happy. 😊”
– Annie’s Pet Parent
Cancer Type: Soft Tissue Sarcoma – on the paw of a Sheltie
A tumor at the same location on the toe was removed 3 years prior to IsoPet® treatment. When another tumor resurfaced they tried IsoPet® Precision Radionuclide Therapy™ – PRnT in 2021 and the tumor never resurfaced again and Annie has remained cancer free for 3 years before passing from an unrelated illness.
New Atlas – horse
“I am so grateful IsoPet® was an option to treat the sarcoid near Atlas’s eye. Even though it was a tricky location, the procedure was easy for him to handle, there was no wound aftercare, and he was able to return to his normal activities right away. It has been a little over three weeks since his treatment and I have already seen a dramatic reduction in the size of the mass, and I continue to see the sarcoid flattening more each time I go to the barn.”
– Sue Johnson, pet parent
Cancer Type: Recurring sarcoid
Treatment Date: January, 2025
Treatment Site: The University of Illinois College of Veterinary Medicine
