My dog started coughing last night, sounds like a seal. It lasted for about 45 minutes and he was able to sleep. This morning it has started again.

Hello. Coughs are quite common in older pets, but that does not mean they are not serious. But the first thing that needs to be done is a good physical examination to listen to the heart for murmurs & the lungs for sounds of congestion. Coughs can be cause by infection, like bronchitis, pnuemonia & tracheobronchitis, heart failure, lung disease, tracheal problems, or from heartworm disease. Once the underlying cause is found, the appropriate medications & treatments can be recommended. I do hope Lucky is feeling better soon & thanks for contacting Petco Pet Education Center, formerly Petcoach.
