הכלב יצא ללא קולר.

A common pronunciation is:

ha-kélev ya-tzá le-ló ko-lár

With vowels added, it would be:

הַכֶּלֶב יָצָא לְלֹא קוֹלָר

A few quick notes:

• הכלב = ha-kélev
• יצא = ya-tzá
• ללא = le-ló
• קולר = ko-lár

The stress is usually on the last syllable of יצא, ללא, and קולר.

The ה at the beginning is the Hebrew definite article, equivalent to English the.

So:

• כלב = dog
• הכלב = the dog

This prefix is very common in Hebrew. Instead of using a separate word like English the, Hebrew usually attaches it directly to the noun.

יצא is the 3rd person masculine singular past form of the verb לצאת, meaning to go out / to leave.

It matches הכלב because כלב is a masculine singular noun.

So:

• הכלב יצא = the dog went out

Related forms:

• הכלבה יצאה = the female dog went out
• הכלבים יצאו = the dogs went out

Hebrew verbs in the past tense usually agree with the subject in gender and number.

The dictionary form is לצאת, which means to go out or to leave.

The root is י-צ-א.

In this sentence:

• לצאת = infinitive, to go out
• יצא = past tense, he went out

This is a very common Hebrew verb, and you will see it in many everyday expressions.

ללא means without.

So:

• ללא קולר = without a collar

Hebrew also often uses בלי, which also means without:

• הכלב יצא בלי קולר

Both are correct, but there is a small style difference:

• בלי is more common in everyday spoken Hebrew
• ללא can sound a little more formal, written, or official

So this sentence is perfectly natural, but slightly more formal than the version with בלי.

Here, קולר is indefinite: a collar, not the collar.

So:

• ללא קולר = without a collar
• ללא הקולר = without the collar

In this sentence, the meaning is general: the dog went out not wearing any collar. That is why קולר appears without ה.

Yes. הכלב יצא ללא קולר is a normal and natural Hebrew sentence.

Literally, it is structured like:

• the dog
  • went out
    • without a collar

Hebrew word order is somewhat flexible, but this is a very standard way to say it.

You could sometimes hear a variation like:

• ללא קולר, הכלב יצא

But that sounds more marked or stylistic, because it emphasizes without a collar.

It can mean several related things depending on context.

Common meanings of יצא include:

• went out
• left
• came out
• went outside

In this sentence, the intended meaning is something like:

• the dog went out
• the dog went outside

The exact English translation depends on context, but the Hebrew is very natural.

קולר is generally treated as a masculine noun.

For example:

• קולר חדש = a new collar
  masculine adjective: חדש

If it were feminine, you would expect חדשה instead.

Knowing the noun’s gender matters because adjectives in Hebrew usually agree with the noun.

Yes, but in everyday conversation many speakers would be slightly more likely to say:

הכלב יצא בלי קולר

That is because בלי is very common in speech.

The version with ללא is still completely correct and natural, especially in writing, formal speech, instructions, reports, or descriptive narration.
