Hey all,
I have a 7 year old lab/golden/chow mix named Moose. He's mostly lab, and is a great dog who still acts like a puppy. However, my fiancee and I have recently had some trouble in the city of Boston with him snapping at strangers. There are no warning signs, he lunges at strangers while on the leash without warning. However, when he is off of the leash, or at the dog park, he is a fun loving dog. At his dog sitter, everyone loves him, but for some reason he has turned aggressive on a leash. I realize that we have to work with him on a leash, but I wonder if anyone has any other suggestions. Thanks.
