When life gives you lemons... or a highly reactive dog
Hi, I’m Layne, and I’ve been exactly where you are. That’s how I ended up with this job; a rescue Stafford threatening to fee fi fo fum people and dogs, Chester had me in the deep-end and frustratingly isolated!
I was already a trainer and had lived with strong-willed and reactive dogs before but none matched Chester's needs. It was a really hard advocating for a dog who threatened everyone but was so desperately in need of connection. I always say to clients, no one truly understands until they've lived this.
So, off to school we went, to learn from the best I could find, and my dangerous dog transformed into an inspirational training partner, actively helping my clients with their fearfully aggressive dogs. Chester's legacy is not only in those dogs who can now socialise but in all the dog's I've helped since. Human-directed aggression requires skills, hypervigilance and confidence that I refined as his guardian, which continue to keep me safe when supporting dog's in distress. Chester is the very reason why I can help you today. He was a gift in disguise.

“I had the chance to watch Layne work with the dogs in a shelter in Thailand and was amazed!! She is such a positive, calm and structured delight and I'm impressed how the doggies react to her. She really understands the dogs needs and helps us humans to react correctly. Highly recommend Streetwise Dogs!”
