The investment

Three questions aēv helps you answer.

Is my dog/cat healthy?

Comprehensive testing reveals what's happening beneath the surface — before symptoms appear.

Can I improve its health?

Trend tracking shows whether things are moving in the right direction, panel over panel.

What actions do I need to take?

Clear, actionable recommendations your vet can act on — not just data, but direction.

Practicing preventative care often means simpler interventions instead of costly emergencies later, more quality years with energy and mobility, and less anxiety for your family.

The questionnaire

Built by researchers. Tailored to your companion.

Every species ages differently. Every breed carries its own risks. Our questionnaires are built with veterinary researchers and practicing clinicians to capture the behavioral, cognitive, and lifestyle signals that lab work alone can miss.

The result is a comprehensive picture of your companion's health — one that can surface breed-specific risks and subtle changes before they become visible problems.

Behavioral Assessment

How would you rate your dog's anxiety when left alone?

Signs include destructiveness, vocalization, pacing, or elimination when alone.

The Founder's Mission

I am a dad.
Four kids. Two dogs. Four cats.

For five years, my family went through something hard. My children struggled — really struggled. And during the darkest stretches, our dogs and cats just showed up. Every morning. Every night. No agenda. No words. Just presence.

They did not fix anything. But they held the thread. And somewhere along the way, that thread became the thing that pulled us through.

Their lives are short. Far shorter than ours. Every healthy year we get with them is a year of less fear, less grief, less loss — and a family more capable of handling whatever comes next.

We can understand what is happening inside their bodies. We can catch things early. We can give them a real shot at their maximum healthy life.

That is why I built aēv.
