Thanks folks for the advice.. We have a pretty limited selection where I live
, but I'm going to try our only pet supply store and see what they have. I'm really tentative about correction collars so maybe I will try a harness and see how I make out. I think they did have a "gentle leader" brand harness, if memory serves. I'll keep you updated!
Sola does pull quite a lot now, and she weighs about 30 lbs. I've been trying to teach her the "heel" command but the results are just kind of comical so far.
