Well last night specifically we were doing environmental work: so lots of distraction, new footing, loud noises, etc.
The dogs in our group all train for different things. We have dogs training for personal protection, police work, French Ring, Mondio Ring, PSA, and whatever else happens to tickle someone's fancy
"All changes, even the most longed for, have their melancholy; for what we leave behind us is a part of ourselves; we must die to one life before we can enter another." -Anatole France
