Astroweeks-
I had a shepherd mix with SBS syndrome as well, and tried all sorts of things. We had him on metronidazole off and on, did pumpkin consistently and fortiflora as well as probiotics from Petco (their specific brand worked the best for some reason) and b12 shots. I tried this stuff from Amazon, just on a whim
in combo with the prescription Hills I/D, along with his normal routine mentioned above and he started putting on weight and feeling better! Not sure if it was one thing in particular or a combination of everything! I never had much success with yogurt, but that’s not to say it won’t help you out. We eventually stopped the high calorie supplement and switched him to Wellness core once he put on weight. My vet had mentioned feeding puppy food as well, as its higher calorie usually. Anyways, hopefully you got something from that!
