Providing a freshwater source for the dogs to drink from is ideal and recommended. It is best to have a freshwater supply dog drinking fountain that drains so the dogs are not sharing the same water and that they have fresh clean water. Having a water supply for the dogs is very important as their tongue is the main source of cooling for them and the freshwater helps keep them cool and hydrated. In the middle of summer, it is great fun to put a small shallow splash pool for the dogs to play in and cool off, it is a lot of fun for the park even for the dogs that don’t like the water, they tend to have fun around the pool area.
