"My puppy have have diarrhea{pudding like} for The ultimate two weeks ,be to the vet 2 times for fecal exams.?

both were negative and no parasites,worms etc. Also drinking Solid Gold Puppy Food cannot figure out is driving me nuts!! Bluenose Pitbull 11 weeks old weighs something like 11 pds.
Well, what did the vet enjoy to say about it? No parasites, worms, etc. = commonplace? Sounds like the food that's going in is coming out much the same look. Try a different dog food.
How long have he been on Solid Gold?

Sometimes a change in diet -- particularly from a diet rich in carbohydrates to one rich in protein -- can create a certain amount of GI upset. We've done some looking into BARF diets (Bones And Raw Food, not vomit), and profoundly of the experts warn that diarrhea is a common occurrence when switching to a better quality food. They advise dog owners not to worry, as this is a sign of 'detoxing'..

As long as he's carrying out tests negative for parasites and seems to be drinking well, I'd just be patient for another two weeks or so and see whether the situation corrects itself. At 11 weeks of age, he's awfully young to be away from Mom and litter anyway, so it's possible he's basically adjusting.
have u tried to change its food
Was everything else clear by the vet? bloodwork, no worms, etc?

Try changing foods. Solid gold ingots is a great food but that doesn't mean it is right for each dog. Your puppy's stomach may simply not agree with it.
Put your pup on a bland diet of boiled hamburger and rice for a couple of days and see if the stool firms up. This will just comfort the intestinal track settle down. Didn't the Vet give you anything to firm up the stool like flagel? I would also ask about treating for giardia or Coccidia both of which inflict Diarrhea but are hard to test for.
perhaps you should try using a Low Residue canned food for the puppy. Did your vet check the puppy for Parvo?
Answers:    Maybe your pup is allergic to something in the food? Had that problem with my dog when she was 10 months infirm. Through trial and error, we found out she is allergic to beef & chicken. Also grass (different story). Or the food could just be too rich. I feed my dog a teaspoon of pure pumpkin for the diarrhea, but I would check with your vet.
Your puppy could own a food allergy. Although it's not as common to see in such young dogs, but it is distinctly possible. The top 4 food allergies are wheat, corn, chicken and beef. Trying a food that's specifically formulated for dogs with food allergies is the cheapest way to start (however it's a long process that can take up to 6 weeks to start seeing any improvements). Some biddable brands of dog food that have food allergy diets are Science Diet, Royal Canin, Eukanuba, Purina and IVD. And you want to look for a novel protein source, suchs as venison, duck, lamb or fish. I would call your veterinarian again to discuss possible food allergies and starting your puppy on a trial. During that trial he can own NOTHING else but his food that he is on. You can use that food however to give to him as treats, but you can't go buy some off open market treat which may aggravate the allergy.

If you do decide to go that route, you want to make certain that you switch diets over a gradual time frame of a week. More of the old, a little bit of the new, and by the completion of the week he should be fully switched over to the new food.

Another thing that can cause diarrhea approaching that is giardia, which is a protozoan parasite that's sometimes hard to detect. That is also detected via a fecal sample, but a Giardia ELISA assessment is a very good way to detect giardia, but can be pricey.
