Hi, I've been doing a lot of research on MAR as I would like to get involved with it. I'm looking to get a scent hound. For those of you who don't know what MAR is, it's Missing Animal Response, I'm going to specialize in dogs. What happens is the MAR dog is given something that smells like the dog they are looking for, such as a dog bed or a shirt, then tries to track the animal through sent. I'm stuck between bloodhound and St. Bernard. I somehow have the idea in my head that bloodhounds have the best sense of smell out of any dog. I think I may have researched it in the past, but can't find the article again so I don't know if this is true. If it's not true, I would much rather get a St.Bernard, as I could end up moving to Alaska, and I hear they do well in cold weather. Plus, I think I would end up searching for lost hunting dogs in the wilderness quite a bit, and I believe a St.Bernard is large enough to stand up to a bear if needed. Sense of smell trumps anything though, as I could always put a sweater on a bloodhound and carry around bear mace if needed. I know I'm going to be asked this, so let me get it out of the way. The dog is a pet first, co worker second. I have tons of experience with different types of dogs as I've been raised around them since I was 8. I will however be getting a professional to assist me in training my new puppy in MAR.
