Pets, especially dogs, can spoil not just the grounds at the camp but also the environment that people come to enjoy. Pets can be intimidating for children and noisy for neighbours.
Please, please, do not bring pets to the camp. If you insist on bringing your dog to the camp, please keep it on a leash at your cottage. Besides the possibility of dogs fouling the grounds (the vast majority of dog owners are very responsible in this regard), children are often intimidated by the presence of dogs and many non-dog owners have voiced their preference for the camp to be a "dog free zone".
Also, should you invite guests to the camp, please ensure they understand that their pets are not welcome.
