How Lulu, a 120-Pound English Mastiff, Became Calmer and More Confident on Leash on 30A
At A Glance
Lulu is a 120-pound English Mastiff who came to 30A Dog Trainers with leash aggression around people and other dogs. Because of her size, her owners needed a safer, calmer way to handle walks and public situations.
Through structured training with Monica, Lulu began showing steady improvement in confidence and comfort on leash, even while sessions were still in progress.

The Challenge
Mike Engstrom reached out because walking Lulu had become stressful and unpredictable. Lulu’s leash aggression made encounters with people and other dogs difficult, and her size amplified the challenge.
For large, powerful dogs, leash reactivity is more than frustrating. It can become a safety concern. Mike wanted professional help to:
- Improve Lulu’s leash behavior
- Build her confidence around people and dogs
- Make walks calmer and more controlled
- Feel supported throughout the training process
The Training Approach
Training focused on calm structure, confidence building, and clear communication, while supporting both Lulu and her owners.
What training focused on
- Teaching Lulu how to stay calm and engaged while on leash
- Gradual exposure to people and dogs at safe, controlled distances
- Building confidence so Lulu felt less overwhelmed
- Coaching the owners so they felt confident handling walks
This type of leash and reactivity work is part of the training services offered by 30A Dog Trainers and is especially important for large breeds.
Throughout the process, Monica remained patient, supportive, and hands-on, helping both Lulu and her owners stay consistent and confident.
The Results (Progress So Far)
Even before completing all scheduled sessions, Lulu showed noticeable improvement.
What has improved
- Lulu is more confident and comfortable on leash
- Reactions around people and dogs have reduced
- Walks feel calmer and more manageable
- Owners feel supported and confident continuing training
Leash aggression takes time to resolve fully, and Lulu’s progress highlights the importance of consistent, professional guidance.
