@nayte My tips:
If you are interested in specific type of dog, which it sounds like you are (athletic, but minimal prey drive), do some research on breeds and breeders and go that route. If you do go with a purebred you'll probably end up having to wait for sometime (maybe years) for a puppy to be available.
Yes, go to training. Reliable recall is a huge quality of life thing, and also not a quick thing to train because its more about your relationship with the dog (Are you more interesting than a squirrel? If you aren't good luck getting a reliable recall). Also, dogs that aren't interested in chasing discs are probably harder to train because they are harder to reward/relationship with.
Don't get to caught up on training methods. People are really polarized. I'm not going to advocate for a particular methodology, you'll learn about the ones that work for you but make sure you select a trainer that works for you - and gets results (almost anyone can be a dog trainer).
Crate train it. This a huge thing for managing and living with a dog that most new dog owners don't do. I am not saying you need to lock your dog in a crate at all times or whatever, but a dog that is happy in a crate can have so much more freedom. And with puppies it is so helpful for teaching them turn off, and also not pee in your house.
Get a long line, don't let it off leash until it can come when its called or you are in a structured environment. You are probably looking at several years of life with a dog on a long line BUT on the other side of this you will have a much better dog for outdoor life.
