Iako joj je veterinar pregledao šapu, ona još uvijek ne voli kad joj netko dodiruje njušku.

Because it refers to her in two different parts of the sentence:

• Iako joj je veterinar pregledao šapu = Although the vet examined her paw
• kad joj netko dodiruje njušku = when someone touches her muzzle

In both places, joj is the dative singular form of the pronoun meaning to her / her.

Croatian often uses the dative pronoun where English uses a possessive:

• pregledao joj je šapu = literally examined to-her the paw, but naturally examined her paw
• dodiruje joj njušku = literally touches to-her the muzzle, naturally touches her muzzle

So the two joj forms are not redundant; each belongs to its own clause.

Because Croatian uses different pronoun forms depending on the grammatical role.

• joj = dative singular (to her, often used for someone's body part or something closely associated with them)
• nju = accusative singular (her as a direct object)
• njezinu / njezine / njezin = possessive adjective (her in the sense of her own)

With body parts, Croatian very often prefers the dative pronoun:

• Veterinar joj je pregledao šapu.
• Netko joj dodiruje njušku.

This is more natural than repeating a possessive adjective like njezinu šapu or njezinu njušku, although those can be grammatical in some contexts for emphasis or contrast.

Both are in the accusative singular because they are the direct objects of the verbs:

• pregledao šapu = examined the paw
• dodiruje njušku = touches the muzzle

Their dictionary forms are:

• šapa → šapu
• njuška → njušku

These are feminine nouns, and many feminine nouns ending in -a change to -u in the accusative singular.

Pregledao is the past active participle used to form the Croatian past tense, together with je:

• je pregledao = examined / has examined

This form agrees with the subject:

• veterinar is masculine singular
• so the participle is pregledao (masculine singular)

If the subject were feminine, it would change:

• veterinarka je pregledala šapu

So pregledao tells you the subject is masculine singular.

This is because Croatian has clitics, short unstressed words like je and joj, which usually appear in the second position of a clause.

In the clause:

• Iako joj je veterinar pregledao šapu

the clitic group joj je comes very early, after the first element of the clause, which is normal Croatian word order.

This is one of the trickiest things for English speakers, because Croatian does not place these short words where English would. You often have to think in terms of clitic position, not English-style subject-verb order.

Iako means although / even though and introduces a subordinate clause.

So:

• Iako joj je veterinar pregledao šapu... = Although the vet examined her paw...

This is different from ali, which means but and connects two more equal clauses:

• Veterinar joj je pregledao šapu, ali ona još uvijek ne voli...

So:

• iako = although, even though
• ali = but

Both can often translate naturally into English, but grammatically they work differently.

Yes, Croatian could leave it out:

• Iako joj je veterinar pregledao šapu, još uvijek ne voli...

That would still be grammatical.

Croatian often omits subject pronouns because the verb already gives enough information. But ona can be included for:

• emphasis
• contrast
• clarity
• a slightly more explicit style

Here it helps highlight she after the first clause:

• Although the vet examined her paw, she still doesn’t like...

So ona is not required, but it is perfectly natural.

Both can mean still, but još uvijek is a very common, slightly fuller way to say it.

• još = still, yet, more, another — depending on context
• još uvijek = still, still even now

In this sentence:

• ona još uvijek ne voli... = she still doesn’t like...

Using još uvijek makes the sense of continuing up to now especially clear.

Both kad and kada mean when.

• kad is shorter and very common in everyday speech and writing
• kada is a bit fuller and sometimes feels slightly more formal or careful

So these would both work:

• ne voli kad joj netko dodiruje njušku
• ne voli kada joj netko dodiruje njušku

There is no major meaning difference here.

Netko usually means someone.

In English, after verbs like don’t like, we often say when anyone touches..., but Croatian commonly uses netko in this kind of sentence:

• ne voli kad joj netko dodiruje njušku

A natural English translation is:

• she still doesn’t like it when someone touches her muzzle or
• she still doesn’t like anyone touching her muzzle

So Croatian netko here is indefinite and broad, even though English might choose either someone or anyone depending on style.

This is about aspect, which is very important in Croatian.

• dodiruje is imperfective
• dodirne is perfective

Here, the sentence talks about a general repeated situation or an ongoing kind of action:

• she doesn’t like it when someone touches her muzzle

For that, Croatian naturally uses the imperfective:

• kad joj netko dodiruje njušku

If you used dodirne, it would sound more like when someone touches it once / manages to touch it, a more single completed event.

So dodiruje fits the habitual, general meaning better.

Because Croatian very often treats body parts as closely tied to the person or animal and marks the owner with the dative pronoun:

• pregledao joj je šapu
• dodiruje joj njušku

This is a very natural Croatian pattern. English usually prefers:

• her paw
• her muzzle

Croatian can also say:

• pregledao je njezinu šapu
• dodiruje njezinu njušku

but that is often less neutral and can sound more emphatic, especially if you are contrasting her paw with someone else’s.

Not quite.

• nos = nose
• njuška = snout / muzzle

Njuška is used especially for animals and refers to the front part of the face, not just the nose itself.

So in this sentence, njušku is a good choice if the animal has a muzzle or snout, such as a dog.

That would not be the normal word order.

The clitic pronoun joj and the auxiliary je usually go near the beginning of the clause in the clitic position, so:

• Iako joj je veterinar pregledao šapu

is the natural version.

Croatian clitics do not behave like full stressed words, so placing them later, in a more English-like position, often sounds wrong or very unnatural.

Yes — this sentence shows several very typical Croatian patterns at once:

1. Subordinate clause with iako

   • Iako... = Although...

2. Dative pronoun for possession with body parts

   • joj je pregledao šapu
   • joj dodiruje njušku

3. Past tense with auxiliary + participle

   • je pregledao

4. Clitic placement

   • joj je appears early in the clause

5. Imperfective aspect for repeated/general action

   • dodiruje

6. Optional subject pronoun for emphasis

   • ona

So even though the sentence is not very long, it is a great example of how Croatian expresses ideas differently from English.
