lots of my customers have dogs.if i binned them for having the odd dog poo in their gardens id hardly have any work.....
i cant remember the last time i dragged my hose through dog poo....cat poo is worse as they tend to crap in soil near bushes and its easy to drag you hose unsuspectingly through some..
i always keep my eyes open for crap on the ground whether they have a dog/cat or not....i have some wet wipes in the van for the odd time i do drag my hose through it..
..as for picking it up for customers..i wouldnt but if you feel comfortable doing it and need the money why not?
we have a dog too and picking her crap up is enough for me..
