We have spent the last two winters at a RV resort in Yuma. For some reason, last year we had more snowbirds then the year before whom RV with 2-3 dogs (mostly small ones) but walk them (or shall I say, the dogs walk them) with extension dog leashes; and they failed to keep them on a shorter leash. The park does have a lengthy dog walk, but this occurred on the way to the dog walk.
One lady walked three daschunds at the same time and she let them urinate on the front part of my site and my front tire covers 3-4 times. Finally, I politely confronted her about it, and she did not say anything in response, but if looks could kill, well, I would not be posting this now.
Anyways, to make a long story longer, a few similar isolated instances occurred with single dog owners.
I'm not the type to run to park mgmt. over every little thing, so halfway through last season I bought Repel II Dog Repellant granules and spread them generously over the front of my site.
Result: No Problemo!
Works great in small areas, like the front of my back-in site.
BTW, I like dogs, don't own any.
Repel II available at Wal-Marts or Petco.
