Why does my dog drool excessively at the dog park?

Well, darling, excessive drooling in dogs can be caused by a variety of factors, such as excitement, anxiety, or even just the presence of tasty treats and other dogs. It's like a saliva party in their mouths, honey. Keep an eye on your pup to see if there are any specific triggers causing the slobber fest, and maybe bring some extra towels next time you hit the park.
