Question about landscaping a potty path

[Gracie, Jade, & Barkley]

A few weeks ago I had asked about supplements in regards to dog urine and was told that's a no. Which is fine by me as I hadn't researched it before asking.

Some of the responses were in regards to landscaping an area. I had thought initially that it would be a no go from my hubby, but when I mentioned creating a path out to the potty area he was ok wth it.

Let me give you an idea of what we face. We live on a little more than an acre which is mostly grass. The only landscaping is around the perimeter of the house and a few "islands" with trees and plants.

So, when we step out the door we walk right into a huge grassy area. There is now a path worn down because we step outside together as there is no fence between us and the fields that surround us.
With my other dogs, they were trained to stay in the area, but there was no worn path. I'm not sure how long it will be for Gracie to be trusted enough to go out with us just standing at the door and waiting for her as we do with our oldest dog. Also, I'm not sure I trust my oldest dog 100%. The only thing in his favor is that he's older and I think he's tired of playing all of the childish games. Lol

I can't landscape the whole area that we give to the dogs to use because it would be massive. If I section it off, it has to be able to be easily mowed around. So, I'm thinking of a path hat we could use for her to urinate in and then have it flow into the grassy area where she can poo.
I'm hoping I can teach my 8 yr old dog to do the same. ;)

Any suggestions? Can anyone post pics of what you have done?

Thanks!

Thanks, Cindy. I have looked there. I just thought I'd come here to ask as well. :)
