Why tracking weight gain is harder than it sounds

Day-to-day weights bounce around, making real progress hard to judge from memory.

Changes in appetite are easy to overlook without a written record.

Vets often want to see weight and intake trends, which are tough to recall without notes.

When to contact a vet immediately

A tracker is for patterns over time — it is not for emergencies. Contact a veterinarian or an emergency clinic right away if your pet has difficulty breathing, collapses or cannot stand, has a seizure that does not stop or seizures that repeat, is straining to urinate without producing urine, has severe bleeding, or may have swallowed something toxic (see ASPCA Animal Poison Control).
