Daisy looked awful last night she didn't even act excited to be home she wouldn't even acknowledge Pixie and most of all she did not sit with my husband in his recliner

She always sits in between his legs and watches tv with her Dad but not last night. She kept whimpering every now and then, she just didn't feel good.
She slept in bed with us and slept most of the night.
Pixie even knows bc she is being real gentle with Daisy.
I gave her the denolsyl and about an hour later gave her white rice like the vet said and an hour later her pepcid and in 2 hr I have to give the flaygl. I hope she doesn't throw up. It is enough to make me puke thinking about the meds.
I just came across some horrible news online if it is cirrhosis of the liver that is the last stage of liver disease and it is irreversible.
I am just so depressed over this what could of went wrong.
Did the medication do this or did Daisy have an underlying health issue that went undetected.
I am not going to be online most of the day bc I am spending time with her. I will updated and let you all know how she is doing tonight.
Please be praying for her. Thanks for your everyone support it means a lot to me.
