My 11 week old pup Kahuna HATES the leash! I have never met a dog that hates the leash so much! I introduced it by distracting him with a piece of boiled chicken while I caressed him with the leash so he could learn to associate it with relaxation... Exactly what I did to introduce the collar, which worked well... On or off he wants to chew it! I tried to attach it and just let him drag it around, but he WILL NOT GO FOR IT. Today I sprayed Bitter Apple over the entire leash hoping to deter him from chewing it and for the most part he has, but sometimes he still does... My other technique was going to be using a choke chain for the first bit of lead so the chewing on metal would deter him.... We are on our way to successful leash training, but I was wondering if there's anything I'm not thinking of? Thanks!
