Hyper Dog

Question
Hello,
Last year my husband and I adopted a Australian shepherd/ Border Collie mix.Her name is Tina, She was 2 when we adopted her. We have had her out side with our other dog who is 15 and she is a jack Russell/German shepherd mix.
Tina is really hyper, she knows the command sit. But, when you tell her sit, she rolls over on her back and shows her belly. We are trying to train both dogs to be indoors, so that they can spend more time with my husband and I and our 2 young kids (6 & 4). It is very hard to have them in the house when they don't obey, Tina is just too hyper and we don't know how to stop this behavior. Nikka our other dog, does usually calm down after being in for a little while, but Tina doesn't. Tina jumps on us and the kids and is very hard to manage. She will also wet if my husband raises his voice even a little bit. It doesn't have to be at her for her to do it. We adopted her from the prison dog program her in Kansas. Please help us, help her be the good dog we know she is.

Answer
I have Border Collie and she was the same when she was young. She would run to fast that the grass flew out of the ground.
She jumped on us and other people and chased any that moved.
That did help in competitions as she usually finished faster.
You can't make a dog stop being hyper, but you can control it.
First get her trained. For sit, hold a treat above her head, and since dogs can't look backwards, and they don't like to back up, she should sit. As soon as she does, say something along the lines of, "Sit. Good girl. Sit." then give her a treat. When you master this you can go on to the next lesson. More then one lesson confuses a dog. Lay down comes next. Get her to sit then put a treat in your fist and put on the floor. She'll want the treat and lay down to snuffle it out of your hand. When she does tell her what shes done, praise her, and tell her want shes done. When you master this then you can teach her to stay. Have someone hold her back at a sit, and you walk away with a treat. Keep telling her to stay. After a moment of walking come back and give her the same praise and telling her what she did. You should eventually take away a hold on her. Then she'll have to stay on her own. If she comes go back sit her again and try it over. Keep this up and she'll learn to stay. On walks if she gets hyper then, use a sturdy choke chain and she should learn not to pull. Praise her when she doesn't pull. For the wetting issue; shes afraid of your husband and greatly respects him as leader of the pack. So when he raises his voice, to her its the same as her wild cousin, the wolf, (lead) ready to snap off her head and eat her. When he raises his voice, he could try being down at her level and petting her. Have him get a huge happy, non aggressive bond with her and she probably calm down soon. Hope this helps and feel free to follow up.
