I don't think one can generalise. My next door neighbour had two dogs and a reasonable garden. I never saw the dogs being walked.

You can't generalise, this topic crops up repeatedly, I doubt my neighbours see me walking my dogs but I do. My car is reversed onto the drive,the dogs leave by the side access straight into the back of the car. We drive to the country park and spend about 2 hours there, home and the whole thing is done in reverse. I have tall plants either side of the drive too so unless the neighbours were snooping they'd have no idea we were out walking. Personally I couldn't cope with living in a flat with dogs but loads do. The only thing I would question is whether or not you're allowed a dog by the terms of the lease.

And often, we leave by the front gate which leads on to a green. Same for other neighbours with dogs and I regularly meet them and their dogs.

Not once have I seen my next door neighbour there nor have I ever seen his dogs being walked out to their car. Not once. In ten years.

I agree that an apartment or flat may be less than ideal but that comes down to the owner being prepared to put in the effort - and the miles.

IMHO of course.
