The Future of pet health

How is LongTail different from my regular vet check up?

Most vet visits focus on treating illness once its visible. LongTail is about prevention identifying early signs of diseases months or even years before they cause problems. We provide deeper lab panels, genetic risk analysis and microbiome testing that aren’t part of standard annual tests.

What kinds of problems can you detect early?

Our biomarker panels can flag early signals of: Joint inflammation (arthritis risk) Kidney and liver stress Metabolic issues like diabetes or obesity risk Digestive and microbiome imbalances Nutritional deficiencies Immune and inflammatory conditions

Will LongTail health replace my vet?

No. Longtail Health is not a replacement for professional veterinary care. We give you preventative insights and personalized plans, but your veterinarian remains your dog’s primary care provider.

How does the testing process work?

We partner with licensed veterinary professionals to collect your dog’s blood, stool, and saliva samples as needed. These are analyzed in certified labs. The results are uploaded into our platform, where our AI models interpret 50+ biomarkers and generate a personalized health plan, reviewed by veterinary advisors.

Which dogs benefit the most?

Every dog can benefit, but especially: Senior dogs (early detection of age-related issues). At-risk breeds (e.g., German Shepherds for hip dysplasia). Overweight dogs (metabolic & joint stress). Puppies (baseline health tracking from the start).

Who reviews the recommendations?

Our platform combines AI analysis with oversight from licensed veterinarians and veterinary nutrition experts. Every plan is designed to be practical, safe, and science-backed.
