Every so often I run into a couple of people in the local park that have Border Terriers. They are doing Earth Dog and they keep saying I should try it with Pip. They said it's great was to allow the terrier to use it's natural instincts.
The way they go on about it, I feel a little guilty for not at least trying it. I'm afraid that he might become become aggressive if I start messing with his prey drive.
He's my first terrier (I've always had dobes), and he's so different then the dobes that I'm always a little unsure of what the best decisions are for him.
I would say if your able to participate with certain events, then go for it. Events are controlled somewhat right? No dog should be left to just go his own way, he needs some guidence right. I'm not really sure on what events they have for Border Terriers, but I'm sure it has something to do with rodents. That would be a great way to get exercise.
