Having lived in apartments for most of my adult life and having had the misfortune to live next to dog owners in different complexes on many occasions, I do think it is very unfair on neighbours.
I have lived next to yappers and the ones that hoooowwwwl when the owner leaves and they keep it up all day till the owner returns.
I have lived next to owners and their dogs that make the carpets and the common areas stink of wet dog and urine. Owners that wash their pets in the common grassed area next to the clotheslines with a hose on a Saturday wash day.
I have lived next to a family that started with one dog and ended up with three dogs in a 2 bedroom apartment all barking and climbing up the walls at all hours.
The smell of unkempt animals seeping out into common areas from the homes of pet owners and the noise will drive you mad.
Dogs have no place in apartment complexes. There is no such thing as a quiet and unobtrusive dog for the simple reason that dogs often mirror their owners behaviours and the owners of dogs that wish to inflict them on others in such dense living are usually selfish, self-entitled and arrogant people with scant regard for the community that they want to force to share in dog ownership often against their will.
If you want a dog buy a house and inflict the noise and mess on your adjacent neighbours not in an apartment complex where you can destroy the quality of life for a very large number of people simultaneously.
