I have 2 Jack Russell's. Needless to say they are very vocal. They come to work with me 4 days a week. Ella, the female, has ,and always will have, separation anxiety but it has abated somewhat since I got the youngest Bodie. At the first of the week, they raise Cain at the first guy that walks in the shop. By midday they have become accustomed to folks coming and going and they will ignore everyone. While this is annoying, I know this their nature. Bodie, however, has developed a weird habit, on the ride to work, he freaks out over cows, horses and people walking near the road. I have tried a collar, which helps a little. He also freaks out if I get out of the truck to unlock the shop. I have to leash him to the seat. He looses his mind every time. Today, he will ride in a Carrier. I hate it but I am afraid he is gonna cause me to wreck with his antics. Trained a lot of dogs. This little guy is a great buddy but stubborn as hell.
