How Many Words Can Dogs Actually Learn?
Ever wondered how many words can dogs learn? Most pet parents know their dog understands the basics — sit, stay, walk, treat — and definitely the crinkle of a food wrapper. But just how far can their vocabulary go?
Some dogs can learn hundreds of words, and research shows they understand more than just commands. They link sounds with objects, actions, and even emotions. Whether you’ve got a clever Border Collie or a laid-back Labrador, there’s a lot more going on in that fluffy head than you might think.
Some dogs know over 1,000 words
Let’s talk about Chaser — a Border Collie who learned the names of over 1,000 objects. Yes, seriously. She could fetch toys by name, group them into categories, and even understand simple sentences. Her story shook up the way scientists view canine intelligence.
That doesn’t mean all dogs are secretly learning English, but it does prove they’re capable of understanding a surprising amount. Dogs have evolved alongside humans, and understanding our words — even just the helpful ones like dinner — has been part of that process.
What about the average dog?
You don’t need a genius dog for them to have a decent vocabulary. The average dog can learn around 160–200 words, depending on training, breed, and repetition. This includes:
- Basic commands – sit, stay, down, come
- Daily routine words – walk, dinner, bed, bath
- Fun words – toy, ball, park, treat
- Names – their own, yours, other pets or people
So, if you’re wondering can dogs understand human words, the answer is yes — at least the ones that matter to them.
How dogs learn words
Dogs don’t understand language the way humans do, but they’re brilliant at associating words with outcomes. Say walk and grab the leash — that’s usually all it takes. Over time, these repeated associations become part of their working vocabulary.
Tone matters too. You could whisper cheese from three rooms away and they’ll come running. But say vet in a cheerful voice and they’ll probably still hide under the couch.
Can you teach your dog more words?
Absolutely. In fact, you’re probably doing it already. Every time you use consistent language around your dog, you’re adding to their vocabulary. Try:
- Using the same word for the same thing every time (e.g. toy instead of stuffie)
- Pairing the word with the object or action
- Offering praise or rewards when they respond correctly
Dogs thrive on routine and clear communication. Add in some training treats and patience, and you’ll be amazed how much they can pick up.

Do cats understand words too?
Cats might not be as eager to please as dogs, but don’t count them out. Studies show cats recognise their names and often know the words that benefit them — like treat, dinner, and no (though they might pretend not to).
They’re less likely to respond on command, but that doesn’t mean they don’t understand. In fact, many cats recognise dozens of human words, especially if those words are tied to something they care about. Think food, toys, or their favourite hiding spot.
The difference is that dogs are more motivated to act on what they hear. Cats? They understand. They just don’t care.
Final thoughts
So, how many words can dogs learn? Quite a few — and some can learn over a thousand. But even if your dog only knows ten, those words are packed with meaning, emotion, and connection. It’s not about how many words they know — it’s about how much they love hearing them from you.
