Pets in the RV park

Seems like people don't just take 1 dog camping anymore. I's two, three or more. The average person with a dog on a leash has a hard time controlling 1 dog let alone multiple dogs. The extended leashes only make it worse. People need to understand that other dogs don't understand that a dog on an extended leash is tethered. They see them as free roaming and a possible threat. That causes the properly leashed (6 ft) to become defensive. We have trained dogs for over 40 years and I think those retractable leashes should be outlawed. We've always said it's bad owners, not bad dogs.
