Should i use a halti or a harness?
I am getting my puppy in 3 weeks (when he is eight weeks old).
for training purposes, a chain is best. it not only teaches them the correct ways to sit, stand, and walk properly on a leash, it gives you control that no other leash can.
if you are afraid of damaging you puppy's throat-think not, if sized correctly and placed in the proper area of the neck (the very top of the neck-closest to the jawline) the dog will simply receive a gentle tug when he misbehaves and will relax (can hardly feel it) when acting an a proper manner.
harnesses breed "ugly walks" with pulling and misbehaving. with harnesses you lose control over the dog and therefore the dog can walk at will (throwing shoulders of out socket in the process)
so please get a chain.
