This is a terrible thing that happened. I do think it was a accident or lapse of judgement on behalf of the mother and grandfather. I myself was a young mother, but when I went to shower I placed my son in a bouncy seat, car seat, or other safe place usally in the bathroom with me. I have always had big dogs. Common sense says you have to use caution when introducing a baby into a home with existing dogs. To those dogs a little baby may look like a play toy, or they can get jelous of the owner paying more attention to the baby than the dog. Reesponsible parents and dog owners dont let the two be alone together. That being said this was an accident and a tragedy. The family has to live with the death of this little baby on their concious forever. That is enough to pay for an accident.
