Those are the very concerns I had had also as a single man living alone. I had several dogs when I was in a relationship for 22 years, but sadly lost my partner and all the pets. Since then I have wanted a dog, but worried about care etc. should I not be able. But I heard the pounds are offering up pets for foster care and was thinking of that as a temporary companion, but then knowing I would get too attached and want it permanantly. I have tabled my thought on this...
