My 13 year old lab has had runny poop for as long as I can remember. Vets have squeezed her anal glands twice but it's made no difference.
Vets can't find anything wrong with her but say next stage would be an op which obviously we don't want to do.
Tried swapping her food to just plain rice for a few days which hardened her poop up somewhat but then when re introducing food it's gone back to normal.
Foods we've tried are Arden Grange which she used to be fine with, tried Chappie from recommendations but that's made her worse.
What can I do? Feel really sorry for her not to mention us!
