Sorry i tend to ask questions alot. anyway when we first got mishka her previous owner said she liked to chew on nylon/leather leashes (shes already destroyed a harness i bought her) so she had a chain leash but ut hurt my hand so im now using a very thick horse lead its working but its very long and thick so its hard to handle and i want to get a 15' training lead how can i detour her from chewing it and ive been training (as alot of you already know)to bikejor/canicross what are the best lines for that too and where can i find a cheap xback im thinking about buying one from alpine outfitters? please helllllppp

And should I invest in a martingale collar for short walks/training because she see a harness as work time

Honestly a lot of times that dogs chew leads, its because they are under exercised and bored and had the chance to do so. Seems like you're exercising her properly, and I would say as long as you don't leave a harness or lead on her unsupervised for like hours, she wouldnt chew on it So maybe try only having the harness on right before you go to walk. You could try lupine for starters that has a chew guarantee so if your dog chews it, you send it in and get a free new one.

You could also spray it with something to deter her. We have used the bitter apply spray with Link. I only had something once when he was a puppy and has since left it alone. I personally don't use a martingale collar with Link mostly because I don't think it would discourage him from pulling. We personally use a pinch collar with Link when we are doing any training or walking. We found it highly effective in discouraging him from pulling on the leash.

Thanks and the harness encident was my dads fault he left it on her for 5 sec and she chewed it and I will try lupine thanks so much -sorry for all the questions
