Jinx just got over Pnemonia and will have a dry cough for a few months. He does have a heart mumur as well. The vet indicates that he could live another 4-5 years with good nutrition and lots of love. Will you be that home? He is not nuetered, and because of his age and the murmur he cannot be at this point, but since he is an indoor dog and has no desire to go anywhere without you dont think reproduction will be an issue, He has been wearing belly bands at his fosters and they are normally dry now that he is settled, so the marking shoudl also be a mute issue.
