لو الحيوان الاليف بيهرش، دور على برغوت في فروه.

A natural pronunciation would be:

law il-ḥayawān il-alīf biyihraʃ, dawwar ʿala barghūt fī farw-u.

A more learner-friendly breakdown:

• لو = law
• الحيوان = il-ḥayawān
• الاليف / الأليف = il-alīf
• بيهرش = biyihraʃ
• دور = dawwar
• على = ʿala
• برغوت = barghūt
• في = fī
• فروه = farw-u or farwah depending on speaking style

Notes:

• The ح in حيوان is a deep h sound.
• The ش in بيهرش sounds like sh in ship.
• In speech, دور is often pronounced more like دوّر with a doubled w sound: dawwar.

لو means if.

In Egyptian Arabic, لو is very commonly used for conditional sentences, especially in everyday speech. So:

• لو الحيوان الاليف بيهرش = If the pet is scratching

For a learner, the important thing is:

• لو is the normal colloquial way to say if
• you will hear it constantly in spoken Egyptian Arabic

الحيوان الاليف means the pet or more literally the tame/domestic animal.

It is made of:

• الحيوان = the animal
• الأليف / الاليف = the tame, domesticated, friendly

So literally it is something like:

• the animal the-domesticated

This is normal in Arabic because adjectives come after the noun, not before it.

Also, the adjective matches the noun in definiteness:

• الحيوان = definite
• الأليف = also definite

That is why both words have الـ.

In careful spelling, especially in Modern Standard Arabic, you would usually write:

• الأليف

But in informal Arabic writing, especially online or in casual contexts, people often leave out the hamza spelling details and write:

• الاليف

So for a learner:

• الأليف = more standard spelling
• الاليف = common informal spelling

They mean the same thing.

بيهرش means he/it scratches or is scratching.

In this sentence, it refers to the pet, so the meaning is:

• the pet is scratching
• or more naturally, the pet is itching/scratching itself

The verb is from هرش, which is used for scratching or itching in Egyptian Arabic.

Depending on context, English may translate it as:

• scratch
• itch
• be scratching

In Egyptian Arabic, بيـ often marks the present/habitual tense.

So:

• يهرش = he scratch / scratches
• بيهرش = he is scratching / he scratches

In everyday Egyptian, this bi- prefix is extremely common in present-tense verbs.

Here it gives the ordinary spoken present:

• لو الحيوان الاليف بيهرش = If the pet is scratching

الحيوان is grammatically masculine singular, so the verb is masculine singular too.

That is why you get:

• الحيوان ... بيهرش

not a feminine form.

In Arabic, agreement follows the grammatical gender of the noun, not necessarily biological sex.

In Egyptian Arabic, دور على means look for or search for.

So:

• دور by itself = turn around or can have other meanings depending on context
• دور على = look for / search for

In this sentence:

• دور على برغوت = look for a flea

This is a very useful expression in Egyptian Arabic:

• بدور على... = I’m looking for...
• دور على... = Look for...

Because دور here is the imperative form: a command.

It is telling someone what to do:

• دور على برغوت = Look for a flea

In Egyptian pronunciation, you will often hear it as:

• دوّر على = dawwar ʿala

So the sentence is giving advice or an instruction:

• If the pet is scratching, look for a flea in its fur.

برغوت means a flea.

It is singular because the sentence is saying to check for the presence of a flea. In English we often say:

• look for fleas but Arabic can naturally use the singular here:
• look for a flea

That does not necessarily mean there is only one. It just means:

• check whether there is a flea / any flea present

So singular indefinite is very natural here.

فروه means its fur or his fur, depending on context.

It is made of:

• فرو = fur
• ـه = his/its

So:

• في فروه = in its fur

Since the animal is grammatically masculine, the suffix is ـه.

The ـه is a attached pronoun meaning:

• his
• its

So:

• فرو = fur
• فروه = his fur / its fur

Arabic often expresses possession this way, by attaching a pronoun directly to the noun.

Examples:

• بيته = his house
• اسمه = his name
• فروه = its fur

في means in.

So:

• في فروه = in its fur

That is a natural way to say where you should check for the flea.

You are literally searching:

• in the animal’s fur

It is mostly understandable and uses everyday Egyptian features, especially because of بيهرش and دور على.

A few points:

• بيهرش is clearly colloquial Egyptian-style
• دور على is very natural in Egyptian speech
• الحيوان الأليف and برغوت are also understandable in Standard Arabic

So the sentence feels like a practical spoken-Egyptian sentence with vocabulary that is not hard for other Arabic speakers to understand.

Yes, depending on context, you might also hear things like:

• لو الحيوان الأليف بيهرش، دوّر على برغوت في فرُوه
• لو حيوانك الأليف بيهرش، دوّر على برغوت في فرُوه
• لو الحيوان الأليف عندك بيهرش، شوف لو فيه برغوت في فرُوه

These all mean roughly the same thing, but the version you were given is already good and understandable.

A learner can get several useful patterns from it:

1. لو = if
2. noun + adjective order:
   • الحيوان الأليف = the pet
3. bi- present tense in Egyptian:
   • بيهرش
4. imperative:
   • دور
5. verb + على pattern:
   • دور على = look for
6. attached pronoun for possession:
   • فروه = its fur

So this one sentence gives you a nice sample of everyday Egyptian grammar.
