Hello community, My name is Veldie, I live in San Diego and I need some insight on telling me how to go about teaching and training my new German Shepherds puppies, and they are brothers 5 months old and I have had them 3 days now. How do I go by teaching them to go poop and piss in the patio area which is connected to the Master Bedroom. I have not walked them yet because of their shots that will be handle on Friday morning. That is my second Question? Before I got the 2 G.S.P. and got them home and introduced them to my other K-Nines which is 2 chihuehues Father and Son, 4 years old and 2 years old. How do I go about getting them to interact with each other and play. I play with all 4 of them at the same time. Then minutes later my 4 and 2 start showing teeth and turn and walk away. What is it I should do to get them to interact? Shadow is the dad and Kango came a year and a half later, and showing teeth he did to is son also and I have forgot to write that down on how long it took before they started playing. Now I have 2 G.S.P. What should I do how to go about it.?
