Should I charge for pets

[David P.]

It's been about a year since I have purchased my 1st rental property with existing tenants. tenant has 2 small dogs.. I didn't charged for having them but now I'm reconsidered to charge a monthly fee they do pick up after them but the yard does need some maintenance grass brown spots and dry urine spots on the concrete would it be right from not charging them to charging them I plan to once the lease is up.
