adopt a puppy?

Now that I've had a dog-free 5 days, still debating about a replacement for Ditto. Should I get one? Will I be able to care for it?
My next dilemma-should it be pure breed? or a stray? a puppy or an adult? an abandoned dog?
Unfortunately, my ability to care is not the only factor. Do I have the stamina to field all the jibes, and even a near-assault that are directed at dog owners? Things that are tolerated from stray dogs are unbearable from pets.

True, my health will suffer. Solitary walks are no pleasure and already given up.
