Hi everyone, new to this group, last Friday I bought a 11 week old blue staff . He had a cold at 9 weeks had a course of antibiotics then had his kennel cough vaccine a week after when the vet said it's all cleared. But he keeps making what I can only explain is like as if he's regurgitating the last 3 days, I went to the vet this morning explained everything and was told to wait till Monday. But today now he is sneezing and a load of gunk/ snot was all over my carpet. Any advice would be greatly appreciated.
