Have you ever wondered how many words a dog knows? When I write about Buddy the Beagle, I tend to humanize his ability to process English. After all, I am a fiction writer. In my stories, Buddy listens intently to his humans and picks up new words from their conversations.
Contrary to my imagination, my real life interactions with Buddy pair words with action. If we’re on a walk and he tries to gobble garbage, “No” is accompanied by a tug on his leash. When I want him to “lie down” or “roll over,” I use hand signals in addition to verbal commands. “Good boy” is usually accompanied by a treat.
Truthfully, my dog reads more into my body language than my actual words. He also recognizes my tone of voice and facial expressions to understand what I mean. If I smile and excitedly say, “Let’s go for a walk,” Buddy trots to the door.
Dogs process speech in much the same way as human infants do between six and fourteen months. With repetition, both dogs and babies associate certain words with actions. Dogs do listen to human speech, but they don’t consider different letter sounds important. A growing vocabulary requires phonetic precision.
All of this makes sense, unless your dog is the smartest dog in the world. A border collie named Chaser proved dogs can differentiate between words. Chaser’s owner, Dr. John Pilley, taught psychology at Wofford U. (no joke)
After he retired from teaching, Dr. Pilley talked to a sheep rancher whose border collie knew how to retrieve specific sheep from the field by their names. When Jeb was told to “go get Millie and Tillie,” the dog picked Millie and Tillie out of a herd of one hundred sheep and brought them back.
When Chaser was two months old, Dr. Pilley started teaching her proper nouns, beginning with a blue ball. He used a strategy called errorless learning, which means setting up an environment in which the subject cannot fail. He would name it, show it to her, say “catch blue” and throw it to her.“He’d put it in front of her and say “find blue.” On the third day, when she could retrieve the ball from another room, he knew it was time to move on to another object. At the end of the fifth month, Chaser had learned forty words and kept them in her long-term memory. During the course of Chaser’s lifetime, she learned one thousand nouns. Dr. Pilley and Chaser changed the field of dog intelligence using the power of play and positive reinforcement.
Reading about Chaser inspires me to start a list of words Buddy knows.
Hmm… are you noticing a pattern? Food is one category of language Buddy understands. And he can always find it. Like many dogs, Buddy is also good at math. I love this quote by Phil Pastoret.
“If you think dogs can’t count, try putting three dog biscuits in your pocket and then give him only two of them.”
Are you tuned into your dog’s language abilities? Leave a comment and let me know the details.

Dogs are smart and I agree, they understand our vocabulary. Facebook shows many examples of this…fun to watch those sweet dogs and be amazed.
