Junior Dog: Age Range & Life-Stage Reference
Written by FurStage Editorial Team
Junior
The adolescent phase — high energy, boundary-testing, and still filling out physically.
Care-guide bands are educational. Dog senior care begins at 75% of estimated lifespan, not a universal birthday. Cats are senior above 10 years; the 15+ page is an editorial subdivision. Human-age equivalents do not determine clinical stage.
Junior Dog care tips
- Exercise: Channel adolescent energy into daily walks, play and enrichment.
- Keep training: Reinforce cues; teenage dogs test limits, so stay consistent.
- Diet transition: Move from puppy to adult food at your vet's recommended age.
