I definitely need a dog and have had dogs all my life apart from when I was first married the first time, and we lived in a flat and were not allowed to have pets.
I used to adore having puppies and watching them grow up (far too quickly) and their quirkiness, but since having an accident I could no longer handle a puppy and indeed cancelled an order for one after my accident.
An older dog is also not so wild and not so much work and as I am unable to bend well, an adult dog suits me better now.
However with adult dogs, comes often bad behaviour and it is harder to train an adult dog, however I worry about the time when it would be unfair to get a dog due to my age, and I also worry what will happen if I die and have a blind dog and a dog that is timid as she lived in kennels for the first six years of her life.
But back to the question - an adult dog in my old age!
