My dog has been diagnosed with a heart murmur a while ago.
Last month he had a cough and a runny nose that stopped him having his booster jab.
The vet gave him a course of antibiotics which seemed to clear up the cough but now it has returned. Is the cough related to his heart murmur?
I'm just after a bit of free advice really if I can pick your brains. As another trip to the vets and another bill is something i could do without!
