Looking for trainer in Chicago land area
Looking for recommendations for a good trainer/Club for my 11 month old GSD. We currently have a trainer, but I would like to change trainers with someone with a little more experience with GSD. My dog Shadow has started to bark and lunge at kids/strangers when they get a little close (15ft), this started happening about 2 months ago and we would like to continue obedience training. We don't have any children yet, but are planning next year. But I honestly can't tell that if my dog got lose, would he actually bite someone? and that worry's me. We are located in Naperville. Any advice would be much appropriated.
