Dog Training Leashes: Training Leads & Leashes

What is an easy way to leash train my 1 year old mutt puppy?
how do I stop my dog from pulling on and chewing his leach?
So we are going to use a remote collar to train the puppy to never chew the chainlink fence she doesn’t do it often . A trainer on YouTube Solidk9 training recommended. I think it’s better to have a mild stem correction than broken teeth one day. Also going to use to work on her recall she is 80% reliable everywhere but backyard that’s 10% she comes back. What brands on amazon are good? And how do I condition her to the collar?
I've been working with a trainer to make it easier to walk my dog since it became very difficult with him trying to bark aggressively to any dog he sees. He'll pull the leash a lot to try to get there and it's quite a scene.We've tried no pull harnesses, prong collars and there's no use. Trainer mentioned acquiring a halti or gentle lead to help me ease him. He was bitten by other dog when he was a puppy and that's why he's so anxious.It only happens when walking. Is this leash a goodsuggestion?
PULLING: Off-leash, she walks alongside me. Outside, she wears a comfortable harness(pictured). •I stop and use sit command. If I verbally praise her, she jumps right back up and back to pulling. She doesn’t do treats. If I don’t praise her, she’ll stay until I begin to walk again and she’s back to pulling (repeating steps during entire walk). •Gentle leader. She will not walk and acts too ashamed.
I struggle to leash-train my Scottish Terrier, is it rude to try a choke chain?
Our puppy does not understand the leash and when we hook it to her collar she flips around and acts crazy. We want her to get used to it but she is going to hurt herself. We want to get her a harness but what is the best type of harness for a puppy? Some have soft material versus some made out of thinner collar materials. Which is better?
Can I try a dog leash and hair buster on him
What is the best brand for training treats for my dog?
does putting the leash on my ankle and walking around with my dog help him learn to walk on a leash?
How old should your puppy be to start training him to walk with a leash?
Jenny tends to pull when walking on a leash. Any good recommendations for a good harness? Thank you.
