Hi, our dog just found out he had splenic sinus enlargement secondary to anaemia and lymphoma. They gave him the treatment of dex and betamox, and gave us the medication of Imuran and Prednisone for him to take tonight. Our dog just drink some water after he got home and didnt eat anything. We finally let him took the medication, but just 2 mins after, he vomiting with kind of orange liquor with white bubble and the those two medicine tablets he just took, and pee with orange color. We are not sure do we need to try to let him take some more or just let him go for sleep. Thank you
