My 8 month old GSD has always seemed to have a sensitive tummy. He caught Giardia when he was younger (4 months) and since then his gut has never really been the same. He had great firm stools up until that point, Giardia caused really loose stools, and since it's been on/off hard stool/soft stool. Most frequently, the first half of his stool is firm and the second half soft serve, super smelly and light colored.
I thought maybe chicken was the culprit, so I switched him from purina pro plan large breed puppy food to Acana wholesome grains sea and farm puppy recipe a little over a month ago. The ingredients are much better and he really enjoys his new food but I'm wondering why all of the symptoms haven't stopped.
So far, I've tried Fortiflora (which I'm convinced does nothing for him), Bernie's perfect poops (seemed to help a little but not much)... pumpkin, bland diet when he really flares up... but the issues keep coming back. The odd thing is that this isn't constant. He will have great poops for a while then randomly the second half will come out loose. I don't notice any treat/diet changes in coincidence with the loose stools, so I'm stumped.
I know GSD have sensitive tummies so I'm here hoping someone else has gone through this and maybe has advice. I have taken him to the vet but I'm starting to think I need a new vet because mine doesn't do much for him.
Picture of my boy for tax and sorry if this is TMI!
