You sound as if you have looked into things more seriously than your first question suggested.
I have reason to sound negative.
Three families in our street got dogs - without thinking about the problems.
First family had to give away the dog, which developed from being a nice puppy into a depressed and agressive dog.
Second family is walking the dog, it is their third dog by the way - and all of them because of lack of nearness to the family have turned into very aggresive dogs which we all are afraid of.
Third family has a dog and a garden and the dog is never taken for a walk and is never in the garden. It can only bark - that is all.
Fourth and fifth family does what every dog owner should do - the dogs are happy, the dogs are fun and we all like them and pet them.
