I am a first time GSD owner. Schindler is a 2yr old GSD and I have had him for 3 months. Before I adopted him he spent the first two years of his life in a fenced in back yard. He had basic manners like, sit, lay down, and come. He is extremely well behaved considering his lack of interaction the first 2 years. When I first brought him home he knew nothing about indoor manners. lol. He was scared of ceiling fans, blow dryers, and pretty much anything with sudden movements or loud noises. He is very comfortable in the house now. I have given him tons of love and affirmation. He doesnt beg for people food, He lays on his bed when told. Mostly he just loves getting love He is so well behaved. I am just trying to find ideas for continued training. I want to make sure that I help him become the dog he needs to be. He has amazing potentional.
