I've been sort of writing a ZA survivor story (ha) and I wrote in my 16 pound mutt, Tara. She was a rescue (and we don't know who had her before), but, we haven't heard her bark in the three years since we've had her. She growls. But rarely. I guess if maybe she was stressed enough she would bark. But I don't think I would ever put down my dog unless she was suffering. D:
I think she'd be a perfect ZA partner (if she didn't bark?) (hence I wrote her in as a pretty nifty sidekick). And she's in shape and listens to commands well. She can run with me without a leash and still stay close.
As to draining supplies...one ziploc baggie (sandwich sized, filled) would feed her once a day for probably two weeks. She could possibly have scraps too?
Eh, just ball parking the food situation.
