HA!!!!
The GSD is the destroyer of the anything of interest in the back yard, so far she has destroyed, pool pump, above ground pool, several hoses, hose reel, AC line insulation, daughters swing, deck lattice, extension cord, numerous flower pots, numerous flowers have been murdered, nice pair of work gloves, dug up my LMR 400 coax and chewed it in half, 3 wicker chairs, any toy my daughter happens to leave behind, and the list goes on!!
I had to buy dirt to fill 3 huge holes she dug. Strange thing is she is a inside dog, and has never chewed anything in the house. (Except when she was a young puppy and we were visiting my parents house and she ripped all the wall paper off the wall in my parents laundry room). lol
Needless to say she is a high drive dog. Her name is Luna. My daughter calls her a Murderer. This is due the fact she chewed up a Build-a-bear that my daughter happened to leave in the back yard. But we still love her and she is loyal and loving and we take her everywhere I go including fishing and camping. She is just about 2 years old now.
The Mastiff is just a 130lb lap dog. He is adopted. People couldn't afford to feed him. But, he sleeps either beside my bed, or my daughters bed. When we leave to run errands he sits by the door waiting for us to return. And is more than happy when we get back. You can leave for 10 minutes, but if you take the car, when you get back he acts like you have been gone a year! lol
