Our cute little puppy Dodger is the greatest dog,but he barks too much! In the house,out of the house. I am thinking about a correction collar,but I don't want him to be so afraid to bark that if a prowler were around he wouldn't let us know. The collars have different levels of correction and don't hurt the dog,it's just a level of vibration i guess. He is Lab/Australian shepard and I read that Australian Sheps tend to bark a lot to ward off strangers. He will bark at anyone and as soon as there at the door,he is their best friend. He wouldn't hurt a fly. I have worked in the pet business for 10 years now and work around dogs all day at my new job. Still not sure what to do though....any advice?
