A cough can mean significant health issues, or it could mean - a cough.You
have a geriatric dog. In a dog this age, a chronic cough is very likely due
to cardiac problems. Get to a vet and have a full exam with labs done. Don't
self prescribe.

"Our ongoing studies of dogs show that following routine vaccination,
there is a significant rise in the level of antibodies dogs produce
against their own tissues. Some of these antibodies have been shown to
target the thyroid gland, connective tissue such as that found in the
valves of the heart, red blood cells, DNA, etc. I do believe that the
heart conditions in Cavalier King Charles Spaniels could be the end
result of repeated immunisations by vaccines containing tissue culture
contaminants that cause a progressive immune response directed at
connective tissue in the heart valves. The clinical manifestations would
be more pronounced in dogs that have a genetic predisposition [although]
the findings should be generally applicable to all dogs regardless of
their breed."
