My old dog is coughing after park. Can symptoms appear so fast?
Poor Bo! I'm sorry to hear that he's having this problem. No, an infection would not show up within a few hours of exposure - the incubation period for most respiratory diseases is at least 3-7 days.
There are many things that could cause coughing in an older dog like this, including heart disease, bronchitis, allergies, laryngeal paralysis, an infection, or even some type of cancer. Since it sounds like he has been coughing on and off for a while now, I would recommend taking him to the vet for an exam when you are able to. He/she can listen to Bo's heart and lungs, and may also recommend lab work or chest x-rays to help diagnose the problem.
