if/when to start on a prong collar
i have a 9 month old standard poodle puppy i'm training to be my service dog. shes doing well, and so far we've been using mostly positive reinforcement or negative punishment to train. the problem is, we live in the middle of a very busy city and her pulling or going to sniff something she shouldn't can be dangerous. there are e-bikes and scooters zooming down the sidewalk, cars, homeless people minding their own business that my dog has decided she must sniff, cigarette butts, etc. her engagement with me is fine, but if she gets over threshold or excited she'll pull on her martingale and not care about it choking her. i was wondering if a prong could be helpful for solidifying our leash training and keeping her safe when we're walking down a busy street or passing something dangerous. if so, when do you start your dogs on a prong? herm-sprenger says to start at 7-9 month minimum. im looking at a 2.25mm herm sprenger for her.
