If you want a loyal adventure buddy there is nothing better than a lab. I've been in situations in nature where having Rocky with me likely saved my life multiple times. He alerts to any kind of wildlife or people that approach our campsite, and is the best cuddle buddy when its cold at night. We have been through some sub-freezing temp nights together, and literally hung onto one another for dear life. He comes into Home Depot, Bass Pro Shop etc with me off leash and is always a big hit.
Also, when off leash outdoors labs are known for not running away or following scent trails. Rocky will run around the woods, play in the river or lake, and come back to check in every couple minutes. If I call he comes running, every single time without fail. Malamutes/huskies and any hound dogs are nightmares to camp with. I once went on a trip with a girl that had a husky and we spent the whole trip tracking the dog after it took off chasing a deer. Two days later it showed up with bloodied raw paws.
