I'm planning on buying a sheltie puppy soon. I've never personally owned a sheltie before, but I've had multiple family members who have, so I know a little bit of what to expect with them. They've always been a favorite of mine and I can't wait to have a loyal, intelligent sheltie of my own. I've been talking to a breeder since March who specializes in conformation. I've been wanting to get into showing dogs and talking to a lot of people in my local obedience/agility Club. I'd love to learn how to handle in a show ring, but I've wanted to get into a agility more because it just seems more fun and rewarding. The breeder ive been talking to sends me updates here and there since they were born, and they're coming up on 7 weeks now. They are 8 hours away from me, but I've been recommended to them from local people. I've been wanting a girl, because I've been around so many male shelties that I'd rather see what a female is like. The two females the breeder have though might not be fit for show. One is lighter boned and is smaller. The other one looks more fuller, but has an a bit of an undershot bite, but says there's a chance she could grow out of it. Just on looks I'd go with the latter, but either way I'm more likely to learn agility with them. I don't think an underbite should get inhibit a dog from running and jumping? (I'm also concerned about looking out for anxious and neurotic individuals.) What are things I should be asking myself and this breeder before I settle on a puppy? I've been following this litter before they were born so I feel like I'm a little already attached.
