[Narrator] He might be barking, but it will be slightly higher-pitched than when he barks to alert you at home. Many times, a relaxed dog will roll over and show you his belly, too. If your dog is afraid or overwhelmed, his tail will be hanging low or tucked underneath. When other dogs approach to say hello, he'll look away as if to say, "I can't see you." Some dogs will bark when they're afraid, and will often back up at the same time. Your dog might even be licking his lips or yawning.

[Narrator] It's not uncommon for dogs to get too rough when they play. You can expect to hear some barking or growling, but if one dog starts to get too rough you may hear a quick yelp.

Remember, going to the dog park should be lots of fun, and is a great opportunity to exercise your dog. If you know what signs to look for, you'll have a better understanding of what the dogs are saying to each other. You'll also know if your dog is having a good time or if it's time to head home.
