A few things you should be aware of......

• Site prep is critical if you want the artificial turf installation to look good and last. Not the best DIY project if you have never done it before.
• Artificial turf can heat up significantly if in full sun.....like too hot to walk on with bare feet. Something to consider.
• It is relatively easy to clean up after your dogs and the turf should be hosed down periodically anyway.

I dont know where you live but where i live artificial turf gets burning hot and will burn your little dogs’s paws when its more than 80 degrees out

Any above ground pool that is small enough to fit into that tiny space is not going to be of concern to the turf. But it will seriously constrict access to the back garden and its suitability/usefulness to both you and the dog.

You can cover a small section with pea gravel and train your dog to use that.

if you hose off a plastic carpet.. where does the watered down excrement go??? ... you might want to move.. before the carpet needs to be removed if it moves thru the product ......

and if it doesnt end up under such.. it will all drain to the neighbors yard.. and that would seriously piss me off if it were mine ...

my first thought was to question the veracity of a 'very good' landscaper... until you said he had no experience with this.. so my estimate of him went up a lot.. lol ..

i think this will be a very expensive mistake.. and i would NOT do it.. fwiw...

where are you.. and does it snow or is there ground freeze.. that might all end up worse than too hot... big city name ..

keep us posted.. live and learn ...

if the dog needs a water feature.. buy a kiddie pool for wallyworld or what not.. you really dont have room for a 'pool'....

Ken, ken, ken......of course any feces should be picked up and disposed of, the same as one would do with a small patch of real lawn and a dog, not blasted into oblivion with a hose!! btw, snow or ground freeze has nothing to do with the application/use of artificial turf, just like it has nothing to do with maintaining a real lawn.

Agree with gardengal48’s comments. BTW, I recently saw an a display in a flooring store near me that was advertising artificial turf that stays significantly cooler in hot weather. I’ll try to get the brand name. we have artificial turf at our second home near Palm Springs. It does get hot in hot weather, however, I just did a quick hose down before our little dog went out to do his thing. I picked up immediately & hosed off the turf on a regular basis.
