Hi again Zita,
Thanks for your quick reply regarding Chewy. If there hasn't been a diet change, then this fecal color change is likely due to the bone. If Chewy managed to ingest the entire bone this can make the feces extremely firm and potentially even cause constipation. The mere color of the bone can cause the feces to turn either very pale yellow/white (depending on how much bone was ingested) to a lighter shade of brown - as seems to be the case here.
This fecal color change should settle in the next 3 - 4 days if this was primarily just due to the bone - so long as he doesn't eat any other bones during this time. If he is struggling to defecate (poop), then you may need to switch him to a soft, wet food for a while (instead of biscuits), and perhaps even add a little Metamucil to his food twice daily, or add on a little cooked, mashed pumpkin. The high insoluble fiber content in these additives will help to get things moving for him again.
Finally - make sure he doesn't get any other bones if possible. Also be sure to keep him up to date with deworming treatments and get this done today if you can. You can use a reliable product like Drontal
or Milbemax which you should be able to get from your local Vet.
