Hi sorry to bring this unsavoury subject up especially when you've all enjoyed your sunday roast but my gsd bitch has done a couple of poos today and yesterday which started of very hard bobbles of yellow poo but then carried on with normal poo but when i went out to the garden a bit later to pick it up the yellow stuff had gone completely white and very crumbly!Any ideas what this coulb????Thanks in advance!

Has she had a bone to eat in the last day or so? It sounds very much like 'bone-poo'.
:)

has your dog been eating any bones? it sounds like that to me - just like the white dog poo you used to see in the old days ;) lol

maybe a raw feeder can confirm if this is the type of poo seen after bones?

Sounds like bones to me too:d

yes, =bones. been picking some up today just like it, if you squint you can imagine theyre a crop of mushrooms :D
