Correcting Unwanted behavior

Hello,

First, I would like to thank you once again for the excellent Forum. It has really been a help to me and Gunnar. He is now 10 months, and I still have a few training issues with my little guy. I enrolled him in Basic Training classes, and he had his last class this past Tuesday, but nothing has really changed, behavior wise from the first day of class up to now. I finally worked up the nerve to address this with the instructor, and she said she had a problem with JRT's, they are too "hyper" for her tastes. Needless to say, I gave her a piece of my mind and I am in the process of requesting a refund for the class. At any rate, I want to get my guy in a REAL training class, with someone that can help me better bring out some of his better manners. I live in Indianapolis, IN. Do you have any suggestions? Also, Gunnar eats anything he finds. I now let him loose in the yard to "go potty" and he will take care of his business, then eat dirt, worms, twigs, mulch, and anything else he can put in his mouth. I end up chasing him around trying to get the object away from him. I tell him No, but he just ignores me. Should I start keeping him on the leash again for backyard outings? Any suggestions would be greatly appreciated. Also, Gunnar has this weird thing of if he finds a worm and pulls it out of the ground, he will roll on the ground all over the spot he pulled the worm from, and he does the same thing when he happens upon bird droppings or rabbit droppings. This totally grosses me out, and I cannot understand why he does this. Have you heard of any other JRT's doing this? And lastly, as I stated in the beginning of this posting, Gunnar is 10 months now, but I am still unable to let him have the run of the house. I have to keep him with me at all times, because if not...TOTAL DESTRUCTION! He will run the whole time he is not confined to one room, the only way I can get him to settle down some, is to close off the family room and kitchen and let him have the run of those two rooms. Any suggestions on how I can get my little guy in gear so he can travel around our house with no problems? I don't think we have a problem with boredom, as Gunnar has walks twice, sometimes three times a day, and we have our scheduled play time 45-1hr each day, but really more than that, as he's always engaging me in some play activity with one of his many balls. I work at home, so he is basically with me all the time. Please help me. I want only the best for my Gunnar. He is a great companion, I just need to get the "bugs" out.:o) Thanks for taking the time to read this, and for any suggestions you can give Gunnar and I.
