Almost every weekend we go to our caravan which is in an idyllic, peaceful forest campsite in the New Forest. Our pitch backs onto deep woodland which the dogs absolutely LOVE to race about in chasing frisbee, sticks, tennis balls, or just general rough & tumble. But, the caravans are only 20 feet or so apart - and the noise insulation in them is almost non-existent - so I am petrified that soon one of our (probably non-dog) neighbours is going to (justifiably) complain about the noise levels and we will lose our "little piece of heaven" because I can't find a way to keep Pickle from going totally NUTS as soon as she is off-lead.
OH is now in desperation suggesting water sprays, sonic collars etc which I am really resisting - but I also see his point.... what we are currently doing ISN'T working and it will only take one complaint to have us chucked off the site.
Dogs are allowed on the site - yes? So how real is this possibility of being thrown off the campsite? For how long is she barking? Is it all day or just a couple of times a day? And for how long? Is there anything written in the agreement that says that the dogs mustn't bark?
Have any of the neighbours complained before? Have you talked to any of them at all to see if it disturbs them? Or are you just assuming they mind? They might not even be in at these times when you're concerned. So long as it's not really early in the morning or late at night, I would be surprised if anyone minded, or minded enough to officially complain about it.
I live on the edge of the New Forest and probably know most of the campsites in the area. I wouldn't mind betting that nobody is actually at all bothered, especially as you are only there for a couple of days at a time. The campsite wouldn't allow dogs if they didn't want them there (and dogs do bark! it's not exactly unusual!!) (I'm even wondering, from your description, if it's one quite near to me!)
PLEASE PLEASE do NOT use any aversives. Apart from anything else, she is not being naughty, she's just being excited and happy. And if you punish her for being happy, for being full of life and fun, what message is that giving her? You could end up with a very very damaged dog.
(Have you read the excellent thread on "Aversives" by Top Barks in this folder? It's stickied near the top of the folder. You could even print it out for your OH)
