In our travels to many different campgrounds across the east coast, we have met many RVers who travel with their dogs. We have met dogs that sit quietly and calmly at their sites when people pass by, we've parked our rig next to a rig where a small dog barks for the entire day while the owner is out, and we've dealt with the dreaded "campground charge" when we walk our dog past a site where the other dog needs to make his presence known, effectively scaring us and our pet. Truth be told, our dog, while friendly, has started to do the campground charge at other dogs. This is not ok. My dog is a bird dog and we hunt together during the fall. I purchased the Garmin Pro 550 e-collar to use for hunting, but never really use it for basic training in the house or at the campground. Since her charging is relatively new, we needed to nip it in the butt quickly. This collar has proven to be a very worthwhile purchase. Though it is more pricey than other models available ($399. at gundogsupply and amazon), it has a long lasting battery, it is very high quality, and both the dog collar and the user controller stand up well to the weather. The controller is easy to learn to use, and it has an auto- bark limiter setting should you wish to let it do it's thing on it's own.
Those of you with new-to-camping dogs may benefit from training them with an e-collar like this right from the start. It's benefits in all situations have worked wonders for my dog. Though she is not a flight risk and generally wants to stay around me, her curiosity has caused her to wander into the road. The collar has allowed me to keep her in check and to avoid an accident when trucks and rigs are passing by. Just thought I'd share what has worked for me to help enjoy our dog more on our camping trips!
