Doggie lawn is really imperative when you live in an apartment. It is always been great for me and my two dogs.
However, I have noticed lately that the lawn is not absorbing fluids as well as it used to.
Now my two little dogs seem to make it unusable within two weeks! When it used to last up to two months. I don't know why it's this different, but now at around two weeks, the lawn is soaking with fluid, as if it didn't absorb any of it at all.
Otherwise, a doggy lawn is as important in an apartment with dogs as a chair is.
