Would you have to pay for an extra pitch so you can fence it off for the dogs?
Would they jump the fence?
Would they have enough room all together?
What do the rules of the site say with regards to the control of dogs? Sites here (Spain) dogs must be constantly tethered and never left alone.
DDog sleeps in the zipped-up sleeping part of the tent with us, perfectly warm enough, three of us to choose to snuggle with. Be careful with claws and inflatable mattresses!
We have a box of essentials for camping with pooch: extendable lead, water+food bowls, tweezers for any necessary tick removal, bag of treats, her passport (shows her vaccinations, we've never had to show it, but it's there just in case), extra poo bags, phone number of emergency vets in the local area.
Sites here will ask the breed of the dog, a couple have asked for photos, as some breeds aren't allowed. Take muzzles just in case they insist.
You can get a kind of zipwire type thing to either tie between two trees, or peg into the ground, to attach the lead to so they have more space to move than just trying their lead around a tree.
DDog loves camping, loves the outdoors, loves snuggling at night, loves sniffing round the bbq area on a Sunday morning (Sat nights are huge for bbq nights) for fallen sausages!
You have to be vigilant that other camping kids keep away from the dogs, that the dogs are calmed immediately if they're barking, and that they have easy access to shade and water
Enjoy!
