I've got a static caravan in the Borders but they allow tourers and they allow dogs. I've seen vans with four or five dogs but they must be on leads and you're not allowed to leave them in the vans alone if they bark. But apart from that there's no limits. One of the ladies in the statics has a whole pack of different dogs and as long as they're well behaved its allowed. Best check with the sites you're going to though, they might have different rules.
