Gentle Leader Harness Should I Get The Gentle Leader Harness Collar?

Should i get the gentle leader harness collar? - gentle leader harness

I get an 8 week old pitbull puppy next week, and I understand this dog collar by pulling downward. My question is if I get this chain, even if my dog is a dog and could not have the same application? stop my dog takes forever if you use from the moment he is young and keep the neck, as a permanent measure?
