Overprotective owners

Today I was at the park and witnessed a person (a) get upset with another person (b). The two dogs were clearly playing. But person (a) thought person (b) dog was getting to rough. Person (a) dog clearly was not seeing the threat that the owner was seeing. Person (a) dog was clearly not hurt and was enjoying the play. I find it irritating when people tell other people there dog is fighting or aggressive when the accused dog is clearly playing and the complainants dog is clearly playing back. So people need to not be so uptight. If you think your dog is no longer playing remove your dog. Do not accuse the other peoples dogs of fighting. Some dogs are just plain stronger than other dogs and when dogs play and your dog is weaker does not mean the other dog is fighting. Over protective owners need to get a grip.
