I used a pinch collar on Tessa this morning. She is only 4.5 months old. I never used it on a dog that young and feel bad about it. I am an advocate of pinch collars, used them with all my dogs, just not that young, usually started using them during adolescence.
After 6 weeks of working on not pulling on the leash, some days are still sooo bad that I'd rather not walk at all (of course I can't do that). Yesterday was such a day, morning and night. Stop, sit, whoa, redirect, here, resume walking, on some days works about 60% of the time, and yesterday not at all, and I know she knows very well what is expected of her. She outdid herself and walked down the street on two legs...this morning I couldn't bear it any longer. Returned home, took about 20 links off the pinch collar I had used on my late bulldog, so for her it's more like a Martingale collar with very few prong links on the top of the neck, and resumed the walk.
It took two well-placed corrections to reinforce the "no", and we were fine the entire walk. I don't expect the perfect heel yet, she can walk on the left, right, out (unless I say "here" whereupon she returns to either one of my sides) as long as the leash is totally loose and it was, so there was a lot more opportunity for praise and treats today than usually. So overall, much less frustration for both me and Tessa.
But...is this too young?
