We do not have pets but the dog across the street comes to our house every day and will lick our driveway for hours. It goes home several times and pukes in his yard while he is doing it. Hubby said maybe someone spilled a soda but the dog licks the entire drive way starts at one end works his way up then back down and goes and pukes. The dog owner is irritated at us over it and has told several other neighbors about it. I think my best bet is to continue to ignore the dog and its owner but any suggestions on why he is doing it encase there is something I can do to stop it.
