Hello Binhu,If the chain is heavy you may want to try switching to a different type of chew-proof leash, like VirChewLy.Likely pup is trying to initiate a game of keep away and likes the attention of someone running after them, or they are fearful of the leash still. Pup also may simply not want to walk - in which case you need to evaluate why. If you are asking more of pup than what their self-control, attention span, or energy can handle, many dogs will react with stubbornness, shutting down responding, or getting hyper active.To help pup overcome any fearfulness, check out the article linked below and spend time reintroducing the leash, letting pup drag something light-weight but chew-proof, like VirChewly around the house while you are there to supervise.https://wagwalking.com/training/train-your-puppy-to-accept-leashIf pup simply thinks this is a fun game, use a lighter- weight leash that's chew-proof at this age, and spray bitter apple, bitter melon, or white vinegar on the leash to make it taste bad. I don't know how those sprays will effect metal, so if you stick with your chain leash, do a little research to make sure the acid in those things won't corrode the metal. Many chew-proof leashes are coated with vinyl or something similar over the metal, which shouldn't cause an issue if a coating is present.I would also go back to some basics with heel training - I don't know what situation pup is getting frustrated in, but you may need to use a different method or different training equipment too.Heel Article - turns method:https://wagwalking.com/training/train-a-poodle-to-heelAs hard as it can be, remaining very calm, patient, and consistent in those situations is often most effective. For example, if a pup starts bucking on the end of the leash, you can plant yourself firmly to keep from being pulled over, take out some of the slack in the leash, then simply wait for pup to give up - when pup stops and gives a few seconds of good behavior, reward the good behavior then in a confident cheerful tone of voice command pup "Let's Go" and continue the walk.After pup has walked a little way doing well, then you be the one to turn around and go home - knowing that pup probably needs a break, before pup acts out again, so that pup is rewarded with returning home while they are behaving well still.Reacting like that can be difficult, but calmness, patience, and still insisting that pup complies even if it means taking time, often gains respect best. Heightened emotions, engaging in tug of war on the leash - which will cause a dog to pull against you more naturally (think sled-dogs), getting rough, or giving in and letting pup have their way, can all make it harder in the end. Pup needs to see that you will follow through with the instruction, but can maintain your own calmness and confidence in the process.Dog training is partially being more stubborn and out-thinking your dog, rather than intimidating.Best of luck training,Caitlin Crittenden
