Ginger is absolutely right. The Vet will work out a payment plan with you as long as you can pay for the initial examination. You have not told us what breed of dog or how old he or she is? This helps in coming up with the possible cause sometimes.
Your dog needs a Vet...Now!
PS it does sound like your dog needs to be seen very quickly. It is possible he could have a 'torsion' or intestinal blockage of some kind. I do believe this is an emergency, so just get him to some kind of vet asap. Worry about money later (I know it's easy to say that, and the reality's tough, but dog first in this case!)
ok this is kind of an emergency, financially, isn't it? Also, it sounds like your dog needs to see the vet quickly. How is the vet back there? Is he friendly? Could your Mom, or you, over the phone, negotiate any kind of payment plan?
I really don't know whether this idea would be any use in an emergency (may not be) but do check up on this. I posted a thread back in December about charitable help for vets' fees. I admit I only researched it quickly, so there might be loopholes I didn't spot. But take a look anyway. Can't do any harm. Try and find that post of mine in the "Archives" (link at top of page on main forum I think.)
The thread was called "Vet Fees Assistance for Pet Owners"
Good luck, and I hope your dog is on his way to being a lot better soon, Ginger.
I forgot to add hes having a lot of weakness in his legs he can't stand up for more then a few secs and he's really wobbly(sp?)
