Lesson #8 learned by this pet sitter: Since fall is approaching yards are going to be aerated. The grassy area where I walk Sam and Buddy was done yesterday. If it is dawn, it is very hard to tell the poop from the plugs dug up from the aeration.
Also, be aware of Sam and Buddy digging after they've pooped. It is not good when I am leaning over the scoop poop, they start digging and the dirt starts flying on me :(
