Min hund biter inte.

Because hund is a common-gender noun, also called an en word: en hund = a dog.

Swedish possessives change to match the gender/number of the noun:

• min
  • singular en word: min hund
• mitt
  • singular ett word: mitt hus
• mina
  • plural: mina hundar

So min hund is the correct form.

After a possessive like min, Swedish normally uses the noun in its indefinite form:

• min hund = my dog
• din bil = your car

The form hunden means the dog. In standard Swedish, you normally do not say min hunden.

So:

• hund = dog
• hunden = the dog
• min hund = my dog

Biter is the present tense of the verb bita, meaning to bite.

Its basic forms are:

• infinitive: bita = to bite
• present: biter = bites / is biting
• past: bet = bit
• supine: bitit

So in Min hund biter inte, biter means bites or is biting, depending on context.

No. Swedish verbs do not change for person or number in the present tense.

You say:

• jag biter = I bite
• du biter = you bite
• han biter = he bites
• vi biter = we bite
• de biter = they bite

So biter stays the same no matter who is doing the action.

Because Swedish does not use do-support the way English does.

In English, you say:

• My dog does not bite

But in Swedish, you simply use the main verb and add inte:

• Min hund biter inte

So literally, it is more like My dog bites not, even though the natural English translation is My dog doesn’t bite.

In a normal Swedish main clause, the finite verb usually comes early in the sentence, and inte normally comes after that verb.

So:

• Min hund biter inte

This is standard Swedish word order.

A useful comparison:

• main clause: Min hund biter inte
• subordinate clause: ... att min hund inte biter = ... that my dog does not bite

So the position of inte can change depending on the type of clause.

It can mean either, depending on context.

Swedish present tense often covers both:

• habitual/general action: My dog doesn’t bite
• action happening now: My dog isn’t biting

Without extra context, English usually translates this sentence as My dog doesn’t bite, because that is the most natural general meaning.

If you wanted to make the right now meaning clearer, context would usually do that.

Yes, but ej is more formal, written, or stiff-sounding in many contexts.

• Min hund biter inte = normal, everyday Swedish
• Min hund biter ej = more formal or stylistic

For ordinary speech and most everyday writing, inte is the best choice.

A rough guide is:

meen hund BEE-ter IN-teh

A few notes:

• min has a long i sound
• hund has a Swedish u sound that is not quite like English u
• biter is stressed on the first syllable: BI-ter
• inte is usually pronounced IN-te

If you want to sound more natural, the rhythm is important too:

Min hund | biter inte

with the main stress usually on hund or biter, depending on emphasis.
