Dont have any improvements to talk about.
But yesterday the bad breath drooling and licking are back. Not as bad as it has been.
She didnt eat last night.mainly laid on the couch sleeping with us. Its not uncommon for her to sleep all day,she was never a very active energetic dog. Its not uncommon for her to not eat at night plus she had a pretty big breakfast yesterday.
Sounds like she is more comfortable. If no other improvement at least you gave her that. But let's keep going I would like to see another year or two from her! Keep us posted. Prayers for the pup!🙏
