Leonberger: How should this breed be introduced to another pet?
When introducing another pet to Leonberger, make the first meeting a controlled sequence, not a free-for-all greeting. Keep Leonberger close to a calm handler and use reward-based cues during the first repetitions. Start with scent and barrier work, then parallel movement and brief calm proximity; protect food, toys, resting places, and escape routes. Move from barrier work to shared space only when both animals can disengage and return to their handlers.
What to plan before the first meeting
Leonberger's training is recorded as Leonbergers are very large and strong. Here, that matters because it changes how much reinforcement, repetition, and choice the dog may need to stay engaged.
A safer introduction sequence
- Start with scent and barrier work, then parallel movement and brief calm proximity; protect food, toys, resting places, and escape routes.
- Let the training note (Leonbergers are very large and strong) set the reinforcement, session length, and distance from distractions.
- Move from barrier work to shared space only when both animals can disengage and return to their handlers.
Separate and get help if
Separate immediately for stalking, repeated fixation, freezing, guarding, or any unsafe contact.

A more thorough grooming should be done once a week'and given the breed's size, this will take a fair amount of time. Leos have a thick, full outer…

Exercise: If you live in a city apartment or a house on a small, suburban lot, this may not be the breed for you. Adult Leonbergers are generally calm and subdued, but they still need to have some vigorous exercise once a day. Puppies and adolescents are active and exuberant.
