There are a group of us Dog Mommies at work who don't have children but probably share more stories and photos of our dogs than most people share of their kids.
This is a sad event that happened to one of the Dog Mommies, Marianne, when she took her beloved Rizzo to the local dog park. I don't understand why pet owners are not more aware of what their dogs are doing at all times. Pets are not just something cute to have, they are a responsibility. If you are not going to be responsible, don't have a pet.
