Questions and answers
Checked November 2, 2026 against Loyal's updates and the FDA. We look again every week.
Is there a pill that makes dogs live longer?
Not yet. Loyal's LOY-002 is the closest to approval, with two of its three FDA sections accepted, but no drug is approved to extend a dog's life, and none has yet been shown to do it.
Is LOY-002 the same as rapamycin?
No. Loyal keeps its active ingredients confidential, and describes LOY-002 as aimed at age-related metabolic decline. Rapamycin is a separate drug being tested by the Dog Aging Project.
Can I buy a dog longevity pill online?
Not an approved one. What is sold online as "longevity" for dogs is a supplement, which needs no FDA approval and has not been shown to extend life.
What age is a senior dog for LOY-002?
Loyal describes LOY-002 for dogs aged 10 and over weighing at least 14 lb, whatever the breed.
Will it work for cats?
None of these drugs is being developed for cats. Loyal's work so far is in dogs only.
