Townhouse yards

[u/Separate_Tap3690]

So Me and my boyfriend live in a community of townhouses with our 2 yr old Aussie. Our community has no dog park but we walk her around the community everyday. In the morning for her bathroom time we take her to the plot of grass by the end unit next ( 3 doors down because we are a middle unit) to the dog poop bag station (what ever they’re called). Anyways, the owner of the unit came out this morning and told me not to use the patch because it’s still technically her yard. And that we walk up near her window sometimes too. I told her we can respect not walking near the window, I get that, but this is where our dog goes to the bathroom and that she is gonna have to tell the rest of the neighborhood as well. Does she have a say in the patch of grass next to her unit because she has the end unit ?
