A dog is considered senior in the last quarter of their expected lifespan.1 For small dogs, the AVMA puts that at roughly 8–11 years.2

What the guidelines recommend

WhatHow often
Exam and medical workupOnce or twice a year1 (AVMA: twice a year or more2)
Bloodwork (CBC, chemistry) and urinalysisEvery 6–12 months1
Thyroid (T4) and blood pressureYearly1
Heart screening blood test (NT-proBNP)Yearly1
Heartworm and tick-borne disease testsYearly1
Mouth and teethEvery visit1

Age alone isn’t a reason to skip needed dental work under anesthesia — the vet will look at the whole dog.1

Bring to every visit
