Hi all. New to forum. Have a puppy, Paisley, that is 11 weeks old. Soon after we got her she developed a cough. The vet put her on an antibiotic but it grew progressively worse. Throughout she has had energy and decent appetite. She is perky and sassy! After two weeks the vet didn't like that it wasn't clearing and has her on a 5 day shot protocol and a stronger oral antibiotic. After 3 days of shots she is still coughing up a lot of phlegm and coughs much of the night. During the day she doesn't cough as much. She is about 2.5 lbs but I can see her body growing and changing. I've never had a small dog before so I am not sure how they tend to deal with illness. Can anyone give me an idea how long I should expect her to cough? And would it still be contagious? Thanks!
