have you ever heard of a dog getting bronchitis?
i haven't, but my miss maggie has it. it's quite disturbing to listen to her cough. poor girl!
of course i've never heard of a dog having Lupus either, but she was diagnosed with that 6 years ago. apparently, because of the Lupus, and the drugs she takes for that, her immune system is weak and she's prone to pick up other minor illness.
