A lot of people take their dogs to the dog park and immediately whip out their phone while their pet goes off and does who knows what. But there are actually some pretty important things to know about taking a dog to the park. It's always a good idea to keep an eye on your dog. Definitely try to avoid bringing treats into the park. Dogs can become very competitive over food. It's also a good idea not to bring toys that you're pet won't be willing to share.
