About your trainer, Lulu
I share my life with a 10 year old female German shepherd dog named Gussy who inspired me to pursue dog training as a career. Although GSDs are often thought of as easy-to-train, Gussy was not (and is still a bit of a challenge).
Thankfully, I discovered the joys of clicker training and we both became "crossovers."
As for my non-dog interests, I love traveling, and have visited several foreign countries including France, Mexico, Spain, & England. I speak a fair amount of French, but I used to be fluent (use it or lose it, just the same as your dog's training!). I am a hobby artist, mostly painting dog portraits.
