Some dogs are not trained and have to use the pee pee pads but it can become expensive to continue buying them. Is there anything else that does the job and is efficient?

Even after I put them in separate rooms they won't eat unless they can get to the other dogs food.

Some dogs tend to be really energetic and make a huge mess it's hard to keep up especially if there's more than one dog.

I believe you can allow rover to adjust it depending on the average rate around your area, this can help attract more clients. That's what I understood when I first found out about it.
