You don't have checks?? I suggest your mom request some because if you have a bank account you SHOULD get personal checks as well...

Well I suggest you work something out with your vet then. I'm sure they've dealt with this type of thing before. They should help a sick animal no matter what and this is just me but if my pups were ill or hurt I don't care if I had teh money right then to take them to the vet but I would do it regardless and worry about money later. NOW I'm not saying you should do that but you should REALLY look into other options as far as vets go if your current one won't even accept payments or postdated checks, especially considering how many times you've been there in the past month
