Hvis kaninens pote stadig gør ondt i morgen, ringer jeg til dyrlægen.

Hvis means if and introduces a condition.

So the first part, Hvis kaninens pote stadig gør ondt i morgen, is the if-clause:

• If the rabbit’s paw still hurts tomorrow

The second part, ringer jeg til dyrlægen, is the result:

• I’ll call the vet

Danish uses hvis very much like English if in this kind of sentence.

Kaninens is the genitive form, meaning the rabbit’s.

• kaninen = the rabbit
• kaninens = the rabbit’s

Danish usually forms possession by adding -s, similar to English apostrophe + s, but without an apostrophe.

So:

• kaninens pote = the rabbit’s paw

Also notice that you do not add another word for the before kaninens. The possession is already built into the phrase.

Pote is the natural word for an animal’s paw.

Compare:

• pote = paw
• fod = foot
• ben = leg

For a rabbit, dog, or cat, pote is the most idiomatic choice if you mean the paw specifically.

Gør ondt is an idiomatic expression meaning hurts or is painful.

Literally:

• gør = does / makes
• ondt = hurt / pain / sorely

But you should learn gøre ondt as a fixed expression:

• Det gør ondt = It hurts
• Min arm gør ondt = My arm hurts

So in your sentence:

• kaninens pote gør ondt = the rabbit’s paw hurts

This is just how Danish commonly expresses physical pain.

Stadig means still.

In this sentence it comes before the verb phrase:

• stadig gør ondt = still hurts

That position is very natural in Danish. Compare:

• Hvis poten stadig gør ondt ... = If the paw still hurts ...

English speakers often want to translate word-for-word, but with adverbs like stadig, it is best to learn the usual Danish placement by example.

I morgen is the standard Danish expression for tomorrow.

Even though it looks like in morning, it functions as a fixed time expression:

• i morgen = tomorrow
• i dag = today
• i går = yesterday

So:

• stadig gør ondt i morgen = still hurts tomorrow

That is completely normal Danish.

This is one of the most important Danish word-order rules.

When a sentence begins with something other than the subject — here, the whole if-clause — Danish uses verb-second word order in the main clause.

So the structure is:

• Hvis ..., ringer jeg ...

Not:

• Hvis ..., jeg ringer ...

The finite verb ringer must come before the subject jeg in the main clause because the sentence starts with the subordinate clause.

This is very common in Danish:

• I morgen ringer jeg.
• Hvis det regner, bliver vi hjemme.

Danish often uses the present tense to talk about the future, especially when the future meaning is clear from context.

Here, i morgen already shows that the action is in the future:

• ringer jeg til dyrlægen = I’m calling / I’ll call the vet

So Danish does not need a separate word like will here.

You could sometimes use a future construction, but in everyday Danish the present tense is extremely common for future meaning.

The verb ringe normally takes the preposition til when you call someone.

So:

• ringe til nogen = to call someone

Examples:

• Jeg ringer til min mor.
• Hun ringede til lægen.

That is why the sentence says:

• ringer jeg til dyrlægen = I call / will call the vet

Dyrlægen means the vet.

• en dyrlæge = a vet
• dyrlægen = the vet

In this sentence, the speaker probably means a specific, known vet — for example, the rabbit’s usual vet — so the definite form is natural.

Danish usually puts definiteness at the end of the noun:

• dyrlæge → dyrlægen

Dyrlæge is a compound noun:

• dyr = animal
• læge = doctor

So dyrlæge literally means animal doctor, which is the Danish word for vet / veterinarian.

This kind of compound noun is very common in Danish.

The comma separates the subordinate clause from the main clause.

Here:

• Hvis kaninens pote stadig gør ondt i morgen = subordinate clause
• ringer jeg til dyrlægen = main clause

So the comma helps show the structure:

• If ..., then ...

This is standard Danish punctuation.

Usually, no — not if you really mean if.

• hvis = if (a condition, maybe it happens, maybe it doesn’t)
• når = when (something expected or assumed to happen)

Your sentence is conditional:

• If the rabbit’s paw still hurts tomorrow, I’ll call the vet

That means it is not certain, so hvis is the correct choice.

If you said når, it would sound more like:

• When the rabbit’s paw still hurts tomorrow, I’ll call the vet which suggests you expect that to happen.

Stadig is the best and most natural choice in this sentence.

Danish also has endnu, which can sometimes overlap with still, but they are not always interchangeable.

For ongoing situations like pain continuing, stadig is very natural:

• Det gør stadig ondt = It still hurts

So for a learner, stadig is the word to remember in this sentence.
