We just adopted a lab collie hound mix & she is a great girl. She is about a year old and very friendly, at least to people. Gentle with taking treats and has quickly learned tricks. Crate training is perfect. She is doing very well with us except for barking and other dogs. She has gotten a lot better while in the house barking, but when we take her for a walk, she is all over the place. The one thing that has worked well is using a spray bottle, but while out for a walk it doesn't seems to help. She jumps around, growls, and barks. We have been thinking about a bark collar but I have read some bad things about them. What is the best thing(s) for us to do while walking her?
