Jack Russell Terrier: The first 90 days
During a Jack Russell Terrier puppy's first 90 days, choose manageable experiences and protect recovery between them. Watch Jack Russell Terrier's response closely and change one variable at a time. Sequence sleep, toilet training, handling, food routines, socialisation, and short training sessions with rest between them. Space new experiences with sleep and familiar routines; progress by recovery, not by a calendar target.
What to protect during the first 90 days
Jack Russell Terrier's official fci name is recorded as JACK RUSSELL TERRIER. Here, that matters because it is useful context, but the individual dog's response still decides the next step.
A manageable order of experiences
- Sequence sleep, toilet training, handling, food routines, socialisation, and short training sessions with rest between them.
- Keep the official fci name in view (JACK RUSSELL TERRIER) and make the next step reversible, observable, and easy to stop.
- Space new experiences with sleep and familiar routines; progress by recovery, not by a calendar target.
Pause and seek help if
Pause and seek help when development, appetite, sleep, movement, or fear responses change unexpectedly.
