Your pet gets on your nerves on Monday, Tuesday, and Wednesday, but he or she isn't doing it on purpose. Patience is key to getting through this rough patch. There aren't any authorities around on Thursday and Friday, but it's still up to you to do the right thing. Make sure you pick up after your pet and obey all pet-related rules, even when no one's looking. The weekend can be overwhelming. Don't venture outside with your pet if you don't have to.
