Collar Is Too Thin, And Harness Is Rubbing Away Fur Behind Her Legs. Other Options?

Boo is a papillon puppy, and not yet fully leash trained. She pulls, which is why I don’t want to use just a collar, but her harness is rubbing away the fur behind her front legs. We’ve had a different harness, the type make of what leashes are usually made of *i beleive the term is webbing, but i don’t beleive everyone would know that* and she chewed thropugh two of those.
Are there other options for walking small dogs?

If A Papillon Puppy Growls When You Try To Take Something Away, How Do You Train Them To Stop?

Whatever you do don’t jump away and show fear. It will encourage more aggressive behavior.
Calmy keep your hand above the toy to block your puppy from it.
If your dog is play growling it will immediately back away from the toy.
If your dog seems to get more intense it is challenging you. (you may get bit but it’s a puppy now so it won’t hurt. If you get bit stay absolutely still and act like the biting doesn’t hurt you at all) Use a loud noise like a horn or someone behind you clapping assertively to distract your dog and snap the nasty thought from it’s mind. Calmly take the toy and when your dog is calm give it back.
Just practice constantly taking your dogs toys and food to get him used to it.
