Good morning...my name is Jim and I come from Tampa, FL. I had a GSD for 14 years and lost her in Oct 2014. My wife and I were devastated. We waited 5 years and just got another from a couple in Orlando. She is 1 year old and a beautiful dog, however unknown to us she never had any training at all. She is house trained though. I think we may have bit off more than we can chew.. This dog is a pup, I understand that, but I cannot make her listen to anything I say. My wife an I are both 70 yrs old and she's wearing me out. Short of getting rid of her...any suggestions?
