Ông ấy săn cùng con chó.

Ông ấy means he or that man, with the idea that the man is older or being referred to respectfully.

• ông = an older man, Mr., grandfather, or a respectful male reference term
• ấy = that, and in combinations like this it helps make the phrase mean that man / he

So Vietnamese often uses a social word like ông where English would just use he.

Because in Vietnamese, words like this, that, and similar modifiers usually come after the noun.

So:

• ông ấy = that man / he
• người này = this person
• con chó đó = that dog

This is normal Vietnamese word order.

Yes. In context, ông ấy can function very much like he.

But Vietnamese does not have one single neutral spoken word that works exactly like English he in every situation. Instead, it often uses relationship or social terms such as:

• ông ấy = he, that older man
• anh ấy = he, that young man / older brother-type male
• cậu ấy = he, that boy / young man
• chú ấy = he, that younger-uncle-type man

So the choice depends on age, social relationship, and level of respect.

Săn means to hunt.

In a short example sentence, săn can stand on its own just fine:

• Ông ấy săn cùng con chó.

But in everyday Vietnamese, people often say:

• đi săn = go hunting

So Ông ấy đi săn cùng con chó may sound a bit more natural in casual real-life speech, depending on context.

Here cùng means with in the sense of together with.

So cùng con chó means:

• with the dog
• together with the dog

It emphasizes accompaniment or doing something together.

Both can mean with, but they are not always exactly the same in feeling.

• với is the very common everyday word for with
• cùng often gives a slightly stronger sense of together with

So:

• Ông ấy săn với con chó. = He hunts with the dog.
• Ông ấy săn cùng con chó. = He hunts together with the dog.

Both are understandable. Cùng sounds a little more like shared action.

Con is a classifier used for animals.

In Vietnamese, classifiers are very common when referring to individual things. For animals, con is the usual one.

So:

• chó = dog / dogs as a general noun
• con chó = a dog / the dog / one dog

Using con makes chó sound like an individual animal, which is what you want here.

It can mean either one. Vietnamese does not have articles like English a and the.

So con chó could mean:

• a dog
• the dog

The exact meaning depends on context.

Also, this sentence does not explicitly say the dog belongs to him. If you wanted to clearly say his dog, you could say:

• con chó của ông ấy

The structure is:

• Ông ấy = subject
• săn = verb
• cùng con chó = accompanying phrase

So the pattern is basically:

Subject + Verb + With-phrase

This is very similar to English word order in a sentence like He hunts with the dog, even though the details inside the noun phrases are different.

It is understandable and grammatical, but many learners should know that Vietnamese may also use slightly more natural alternatives depending on the situation.

Common alternatives include:

• Ông ấy đi săn cùng con chó.
• Ông ấy đi săn với con chó.

These can sound more natural if the idea is he goes hunting with the dog.

So the original sentence is fine for learning structure, but in everyday speech you may often hear đi săn.

A few important points:

• ông: ends with an -ng sound
• ấy: has a sharp rising tone
• săn: short vowel, different from sang or sẵn
• cùng: also ends in -ng
• chó: rising tone

The tones matter a lot. For example:

• chó = dog
• changing the tone can create a different word

If you are practicing aloud, focus especially on:

• final -ng
• the tone on ấy
• the tone on chó
