Ok so there is something wrong with my puppy.  I have a Toy Poodle. he is like 5 pounds.  and this morning he came into my room crying.  and I looked at him and his back was hunched up and his two back legs where really straight and he was woobling back and forth.  and it looked like he had lost all controll from the middle of his body down.   No this isnt the first time it has happened.  But everytime I bring him to the vet he has recovered.  So they really dont SEE SEE it and tell me they cant do anything.  But I Think since it happens enough for me to worry then there is something wrong.

So my questions is. What should I do?
