No garden, but a park, is a dog a no no?

[IslaValargeone]

I live in a town house, we have no garden, but a huge dog walking park 20 seconds walk (if that) from my front door. So, does that still qualify me to own a dog would you say?
Much to my disappointment we have ruled out a Dane, as we don't think our stairs would be suitable, we still want a fairly big dog, low shedder if possible. older child friendly, but protective for when my dh is away (we live in town) I am at home all day so exercising is not an issue.
Your thoughts, suggestions appreciated.

When you say 'no garden' do you mean no garden at all, or just a tiny one?

I mean no garden.
(currently negotiating with council but I'm not holding my breath)

There are dog owners on my street, but I think they had their dogs before they moved in so have adapted accordingly, without the issues that toilet training brings.

Oh difficult then.

It's the toiletting issue. We are lucky enough to have a very large garden. The issues without a garden are:-

1. desperate to go out first thing to poo/wee
2. a need to go out during the night took/wee

I have a garden but also live opposite a huge park. I have to say that although I used the garden lots in the early days, now I don't really use it for the dog, he gets walked three times a day and isn't that interested when I go out to do the gardening.
I actually take him out for his early morning/ late night wee to the park anyway. I'm not really sure why, I like a bit of a wander guess.

The only thing that would be tricky is when your DH is away, are your kids of an age where you can leave them to do a late night wee?

I can do late night wee as my dc is 11.
It's going to be impossible for toilet training isn't it?

We're terribly lazy with the late-night wee. My teenage son invented the idea of standing on the doorstep, with the dog on his extendable lead, wandering around the front garden looking for the exactly perfect blade of grass to pee on. It has the added benefit of knowing when he's done one, which is not always possible if we were to chuck him out the back on his own. None of us is up for tramping the streets last thing at night.

Lots of people here have dogs and live in flats, no garden. They all seem to manage fine, although you do have to be quick - my friend has just got a 6mo puppy and is often to be found outside in the dead of night in her pjs waiting for him to do a wee :o
