So my GSD is now 5 months old and is a great little pup. So far *touch wood* very healthy and doing well after his stomach issues as a younger pup. I do have two major behavioral issues I am trying to deal with that I thought you guys may be able to shed some light on.
1. My GSD has tunnel vision whenever my boyfriend's Jack Russel X named Tiny is around. Won't leave the poor thing alone at all, despite protests from Tiny. Prince loves playing with him and most - sometimes all - of my commands are ignored when Tiny is present unless I have food in my hands. He is almost perfectly behaved by himself. The boyfriend and I are starting obedience training with the two later this month (him with Tiny and myself with Prince) so I am hoping that will help in easing his zoning in on Tiny, but any suggestions to get me started would be appreciated.
2. He still bites. He knows what the "off" command means but his excitement unfortunately is channeled into his mouth! He will lunge at your face when excited and if he is close to you and is being worked up by Tiny he'll bite you on the foot, leg or hand (pretty much whatever is closer) from the excitement. I have so far avoided smacking him and have tried using positive reinforcement to prevent this behavior but it's just not working. When I train him he is perfect - I can stick my head right up to his and wave my hair in his face and everything and he won't even so much as lick me, but get him excited when he's playing and I'll cop teeth to the face. (Edited to add he is not biting to injure or being aggressive about it, but those teeth still hurt even when he only nicks you with them!)
Any ideas guys? I don't ask for much, I know.
