What 7 years means for a small dog
This page covers small dogs, meaning up to 20 lb (9 kg), such as a Chihuahua or Jack Russell. At 7 years, they are in the adult stage (2–9 years). Settled, fit, and at their peak. Regular exercise and yearly vet checks keep them there.
A small dog is usually considered a senior from about 10. A 7-year-old small dog comes out at about 44 in human years, up from about 40 at 6 years.
Care notes for the adult stage
- Book a yearly check-up with boosters and a dental check.
- Keep their weight in check, since extra weight strains joints.
- Give regular exercise suited to their breed and size.
