@StruggleBusEq He is expressing his anal glands more than likely. Some dogs express them themselves with no cause for concern. Other dogs need help and you can either do it (not fun) or have your vet do it! Super common! Going off of the color it sounds like normal debris too
@knsequine I work in the vet field and highly recommend Purina’s Fortiflora! It’s a great product. I would also recommend pumpkin (reg puree not the pie filling) to help with digestion as well!
