Hi Freddy-
Did you say you have two G/S pups? Are they litter mates? We have two golden lab neutered littermates. Wow, what a handful!!!! They are 4-1/2 now, and are doing great. But we also had a rough start. Two with loose stools and diarrhea is stressful! Have you checked out the website that I mentioned earlier? I printed the whole section on digestive disorders and refer to it often! It was like a bible for a while.

I used and recommend the Vetri-Probiotics BD, Gastriplex and Phytomucil. Also, I used unsweetened applesauce due to the pectin in it. Instead of pumpkin, maybe you could try sweet potato. You might want to try one of the Victor lines. I think their chicken/rice and lamb/rice both are ok for large breed pups. Their food contains montmorillonite clay which some recommend for colitis.
One of the most recommended brands on this site is Nutrisource. Their large breed puppy formula would be worth a shot as well.
Have you tried feeding a little less food to see if that helps? My dogs are doing great on Pure Vita Turkey and Peas right now, but not sure if the calcium is correct for LB pups. Best of luck to you!
