Adorable JRT! They can be little hellions if they get bored. If you are both gone during the day, crating her would be a good idea, or make sure she has something to do. I have 2 JRT/Rat Terrier mixes, about 6 months apart. Oreo totally understands that he is supposed to stay in the kitchen if I put up the barrier, and is well behaved about it. Nutter, OTOH, feels that confinement = concentration camp and he will do ANYTHING to get out. He can jump 5 ft straight up. if he can hook a paw over a gate/barrier/counter he can pull himself up and over. JRTs are STRONG!! He clawed THROUGH the sheetrock wall, THROUGH the insullation, and THROUGH the second layer of sheetrock between the kitchen and the livingroom in 1 DAY while I was at work. It still amazes me that we didn't have puppy kabobs on the barbie that night.....
So, he started spending the day in an extra large crate with a Kong or one of those "random treat dispensing" toys.
If you have a dog park in your area, take her there. She can run, interact with other dogs and with other people. When I do rescue work with dogs that are timid or have bonding issues, I take them there almost every day. It is fun to see your pup interacting with other people and other dogs!
Obedience training is a MUST and agility training is an EXCELLENT suggestion. If you have kids, it is a great activity for them as well. JRTs will rule the roost if you do not establish yourself as top dog. I think this is why they are so often abused or surrendered. They have a strong will and a wickedly keen intelligence; you have to become top dog in a positive way, otherwise the hellion factor starts to appear.
To bond with others, have them take her for walks, play with her, (fetch is another great activity) brush her, and give her treats.
Be prepared to devote time every single day to wearing her out. My 2 Terrierists could run flat out for 2 hours at the dog park without breathing hard. Terriers were breed to be working dogs. They want to have a purpose, and they want to be busy.
If you have Chickens (which I would assume since you are on BYC

) you need to get her with the chickens/chicks NOW. She needs to learn that they are her JOB, not her buffet. The earlier this is learned the better off you are. My one terrier (Nutter the Hellion) would eat my flock in a heartbeat. Oreo, OTOH, loves the chickens, runs into the coop to give them baths, eat chicken poop, and curl up with them under the heat lamps.
Cheers!!
