The best treatment for the loss of a pet is to get another pet. It really beats hanging yourself.
Just not right away. Wait a month, or in these weirdo's case, a couple months 1st. I bet they were not this upset when their parents kicked it.
They named their dog, "Puppy". Not too into considering options, I guess...
They use to say that about girlfriends (coming from a guys perspective) and I can attest to the fact it works. As far as pets, and once again I speak from experience, wait a few months before getting another ... it gives you time to time to get past the mourning stage and gives you a fresh new outlook when you get your new pet.
That's what I did. Now I have a Ragdoll kitten that is hanging out with me and trying to chase the cursor on the screen. Too cute.
