For me, pets are a member of the family for many many years. They rely on you for everything. If you cannot give them your time then don’t get one. Especially at this time of year I often think of the Christmas campaign ‘A pet is for life, not just for Christmas’.
Lots of people love puppies but I love older animals. There are several photographers who specialize in taking photographs of aging pets. Pete Thorne is the one I know best.
