Border Terrier: How should an owner handle adolescent behaviour changes?

When a young Border Terrier becomes less reliable, return to the last version of the behaviour that was working and rebuild from there. Schedule the first attempt after the dog's normal age-appropriate outlet, not at peak excitement. Return to easier cues, shorten sessions, increase reinforcement, and manage the environment while skills are rebuilt. Keep the easier version in the routine while reliability returns; do not test the hardest version every day.

What can change during adolescence

Border Terrier's exercise is recorded as Borders are active dogs and need plenty of exercise daily. Here, that matters because it changes the amount and timing of movement, stimulation, and recovery this situation needs.

Rebuild the behaviour you want

  1. Return to easier cues, shorten sessions, increase reinforcement, and manage the environment while skills are rebuilt.
  2. Use this exercise note (Borders are active dogs and need plenty of exercise daily) to choose the starting amount of movement and the length of the recovery period.
  3. Keep the easier version in the routine while reliability returns; do not test the hardest version every day.

Arrange an assessment if

Escalate for sudden personality change, pain, disorientation, or aggression that cannot be safely managed.

Most of the time, a quick brushing every week or two is enough to keep the coat in good shape. During shedding season, owners can expect to spend a half-hour or so every day stripping out the dead hair,…

Exercise: Borders are active dogs and need plenty of exercise daily. A brisk half-hour walk or play session with his owner and a ball or flying disc should be enough to keep a Border healthy and happy.

Training: Early socialization and puppy training classes are a must for Border Terriers. The breed's parent club notes: 'A Border was bred to think for himself, which can be both his most endearing and most frustrating quality.
