I am the proud mom of two adorable females, Lucy and Gracie, who are each under 20 lbs, both just under 2 years of age. They haven't given me a day's worry, except for a little barking on the porch, so I never thought about training assistance outside the ordinary treat-based puppy class. :) Then came the boy...Brady. He was a cute, 5 lb. sweetheart when I adopted him, and in 11 months exploded into an 85 lb. Lab-Great Dane mix who was running the household! His favorite game became "you're the criminal and I'm the police dog" - which of course involved jumping, mouthing my arms hard enough to pull me off balance, and barking mindlessly in his deep baritone! I was at my wit's end, and seriously considered finding him a new home on an ice farm at the South Pole...but I couldn't bear to part with the big lug.
