A couple of months ago, we lost our male collie, Tango. It was very sad time for all of us, but especially hard on our female collie, She has been very depressed. We are really happy, becuase she is starting to feel better and bond with us. In the past, she never wanted to come inside, until just recently. She was a "kennel" dog and we didn't get her until she was 9 years old. She is a very sweet dog, but just doesn't bond to humans easily.
