Hi!
Maggie, 1 year old has been recently shifted to a protein rich diet from urinary S/o diet. She is active, having her meals properly as well but there is a chage in her poop colour. Some of it appears black. What could be the reason for the same?
Dark coloured stools can just be dry constipated stools, consistency looks normal. Keep an eye if it continues you can get her liver values rechecked. You can add some extra pumpkin paste to help her with her digestion if there is constipation.
