Barking is as natural to dogs as speaking is to humans. However, canine talkativeness can also be as varied as it is for people — some humans never seem to stop chatting, and the same can be said for some pups. “When we talk about quiet dog breeds, there are some important distinctions to make — it’s pretty rare for any particular breed (or dog, for that matter) to never vocalize in any form at all,” says Catherine Gilmartin, a certified dog trainer in Connecticut. “If you’re discussing breeds that don’t bark much, that doesn’t necessarily mean they’re silent. Sometimes they simply vocalize in other ways than a traditional sounding bark.” With that in mind, these quieter breeds may make good pets for apartments or similar situations.
