Isn't there a bunch of controversy about those harnesses negatively affecting how the pup walks?
There is a tendency to pull in a harness because the dog needs to lean into the front strap to move forward. Every dog should be taught how to loose lead walk on a collar first. It is actually much easier to teach a dog not to pull in a collar, and this then translates much better to a harness, whereas teaching not to pull in a harness is much harder. All our beginner and level 1 classes are taught in a collar (flat or martingale) and then once the dog has mastered loose lead walking the owners can switch to whatever collar or harness they use everyday.
When Deska was more able bodied we'd go bushwalking in harnesses and I'd have a flexi-lead on the harness which, while it gave more freedom, did teach him to pull slightly in a harness (he never pulls in a collar). But that was actually good for me because I have mobility issues and the slight pressure helped stabilise me. But since we don't go bush walking and I rarely use the flexi-lead, he's reverted to his normal walking in a heel position. Shame for me: it's probably one of the few reasons to value a pulling dog.
