Hi Holly,
Sorry I didn't get to this. Busy weekend.
We have an 18 month old BC mix. Not sure what the rest of him is, maybe lab, maybe Bernese mountain dog. I can tell you what we currently do, and what we would like to do. The caveat is that he is not 100% BC, so your results may be different.
We have not tried an obstacle course for him, but you are making me think that it might be fun. What we would really like to do, if our schedules permitted it would be to get both dogs into flyball and/or agility training. To watch Sam sprinting at top speed through the woods, over logs, holes, bogs, debris and whatnot, to chase down another dog (or deer, unfortunately), makes me think he would do great at an obstacle course. Plus, he just naturally seems to want to run on top of logs or climb vertical riverbanks, like he instinctlively wants to take the hard route.
Right now, the dogs just get 2-3 miles in the woods in the morning, usually with a group of 3-5 other dogs. They get another mile or so to a nearby park, plus some catch and tug-of-war with us. Although we were worried that his border collie smarts and energy might be too much for us, he is incredibly mellow and adaptable if he gets enough exercise and social acitvity.
Of course, your dog is new to you, and probably a bit wigged out, so you may not be seeing much of his personality yet. Sam was afraid of anything human for about a month after we got him from the pound.
I hope this helps a little.
