i have a strange question. loose leash walking is our biggest problem. ive tried many different approaches and none have worked very well. now that winter is here and it is dark by the time i get home from work, we are unable to go to our free-run exercise area and i need to walk him around town on a leash. the complication for me is that we start obedience classes on the first week of january. i hesitate to start another wave of loose leash training that might not agree with what the obedience class will teach. which might confuse him even more. is it bad to just let him do what he wants on leash for a month and then hit it hard once classes start?
