I have a 7 year old rottie. She has not ate since Thursday. She barely drinks water either. Her eyes are puffy, her nose looks like it is stuffy. Gave her benadryl (per Vet she thought it was allergy). My dog also have a dry cough/hacking like she is trying to get something up. When she does it is a clear liquid with white mucus. She also has dark very soft stool when she went potty. When I rub her tummy she acts like it hurts? Please help I am VERY worried.

I would definitely be taking her to another vet!

Don't give any human medicaine to dogs, your new vet will prescribe something to help with these symptoms.

Try and feed her some warm boiled chicken with rice, it is the most gentle thing on their stomachs when they are ill.

Try adding just a splash of dog milk to her water to encourage her to drink more.

She definitely needs to se another vet poor thing :(
