I’ll start by saying, I’ve done a lot with dogs. I’ve been training dogs for 10+ years. I do know my dog breeds. And I am pretty darn good at putting a dog through it’s rounds.
That being said, here are a few of my calls:
Labs, not bad dogs, they run reasonably well, though they will probably be a little shorter on the endurance end. They can be smart, but I’ve met very few inteligent ones. (that can be good or bad for you) If you get a pure breed make absolutely sure you are getting one from a good breeder.
Other pointers/hunting dogs, mostly the same as Labs, but thay haven’t been as over breed, so they tend to have less health and mental problems.
Doberman Pinchers. Great dogs, but not for beginners. Someone had previously mentioned these. If you get one of these, make absolutly sure you get to a dog trainer early. These are physically some of the best dogs in the world. Their one obvious draw back, they’ve been bred to be guard/army dogs, so many of them have very strong aggressive tendencies. Just to be clear, I have nothing against them, I would love them, but they are a lot of dog and need a lot of attention.
Border Collie, my current favorite dog. Lots of endurance, very smart, very inteligent (ussually agreed to be the smartest in the world.) Their major drawback, lots of energy (mental and physical) you absolutly have to keep these dogs busy, or else. I love running with mine, almost as much as she loves running. period.
Mutts/mixed breed, probably the best dogs in the world. There have been lots of problems with in-breeding/overbreeding in past years. By some strange scientific/phenomenom mutts have very few medical problems, something about croosing genes or something. The people that run and then win the Iditerod won’t race purebreed dogs. People that show up with a team of Huskies or Malimutes get laughed off the course. Mutts tend to be more hardy. There are plenty of mixed breeds to chose from (pounds, shelters, accidental neighbor dogs doing the tango, ect…) They’re cheap, and for what most people need, perfectly acceptable.
One last piece of advice, what ever dog you get, take some dog training classes, they’ll teach you more about your dog and yourself. Goodluck.
