Swab and mail

About 30 seconds of gentle cheek swabbing, then the prepaid mailer takes it from here. The full step-by-step is below.

Report ready.

An easy-to-read report comparing your dog’s biological age to their calendar age, ready to share with your vet. We’ll email you the moment it lands.

See why the second test tells the real story

Three rules the lab swears by.

Activate before you swab.

An unregistered tube can’t be matched to your dog, so the lab can’t process it.

No food or drink for 30 minutes.

A food-free mouth means a sample rich in the DNA the lab needs. Water counts too.

Send it back right away.

The preservation solution works best when the sample ships fast. FedEx, prepaid, any location.

In the box.

Four components, one job: getting your dog’s cheek cells to the lab in perfect shape.

SafeCollect tube

Preservation solution behind a foil seal. It stands upright in the box while you swab.

Collection swab

Hold it by the handle only and keep the tip clean.

Biohazard bag

Standard practice for lab samples. The capped tube rides inside.

Return mailer and label

Prepaid FedEx. Seal it, drop it, done.

Set the swab up for success.

The DNA comes from cells inside the cheek, not from saliva, so a thorough swab matters. Four moves that make it easy on both of you.

Pick a calm moment.

Collection goes easiest when your dog is relaxed, not wound up.

Practice first.

Rub a regular cotton swab inside their cheek beforehand so the real thing isn’t a surprise.

Ask for help.

A second set of hands to hold or distract your dog makes everything smoother.

Take your time.

Stay calm and keep reassuring them. Patience beats speed.

How to finish your DNA swab

Twelve quick steps, grouped like the printed guide in your box. Your dog only sits still for about 30 seconds of it.

Get set

Steps 1-4
1

Pause food and water. 30-min rule

Nothing to eat or drink for 30 minutes before collecting. Both can interfere with results.

2

Wash and dry your hands.

And keep your phone or tablet nearby.

3

Activate your kit. Can’t skip

Scan the QR code inside the kit box and follow the prompts: the tube’s ID code plus your dog’s details. Finish before you swab.

4

Set up the tube.

Uncap the collection tube and stand it upright in the holder inside the box. Keep the cap close.

Steps 5-8
5

Open the swab package.

Hold it by the plastic handle only, and keep the tip clean.

6

Get your dog comfortable.

Sitting or lying down, with their head held gently still.

7

Swab the cheek.

Lift their lip and slide the swab between cheek and gum line. Rub and rotate for about 30 seconds, roughly 20 rotations. If they pull away, pause and resume.

8

Break the seal.

With the tube upright, push the swab down through the foil seal until it reaches the bottom.

Seal and send

Steps 9-12
9

Snap and cap.

Snap the handle at the break point, toss it, and cap the tube tightly.

10

Mix it.

Gently invert the capped tube 5 times.

11

Bag it and pack it.

Tube into the biohazard bag, bag into the prepaid FedEx mailer, seal both.

12

Send it back.

Drop it at any FedEx location. Sooner is better for results.

*For animal use only. Keep all kit components out of reach of children and pets. Use only the materials provided in this kit, collect from one dog per kit, and never reuse materials, combine them with another kit, or use anything that looks damaged. Follow every step closely: an unactivated kit or unregistered tube may prevent processing and mean no report, and insufficient sample, contamination, improper handling, or shipping delays may delay results or require a new sample.

Then the lab takes it from here.

Your part wraps in minutes. Here’s what happens while your dog gets back to napping.

Finish the health questionnaire.

Quick, required, and waiting in your dog’s profile. It puts their results in context.

Follow it in your portal.

Your portal tracks your dog’s sample from arrival to report, and we’ll email you along the way.

Meet their biological age.

The report lands by email, written in plain English and ready to share with your vet.

Tracking biological age over time is where the real magic is. Trends are what’s worth watching, and worth sharing with your vet.
