No one in your family has freaking $80? How are you even getting by? Even if you don't have the cash, certainly you have something you could sell. A cell phone, a piece of jewelry, a piece of furniture, a stereo, anything. Everyone in your family could donate blood plasma and pay for it. We are not talking about an expensive surgery here, we are talking about an office visit and some antibiotics. If your mom can't afford that for her dog, then she shouldn't have the dog at all in my opinion.
