[dardamavet]

why does my cat have a dog?

[Away54]

It's not the cat who owns the dog. Imagine Andi has a dog and Tini has a cat. Then, Tini sees her cat chasing Andi's dog.

Tini says, "Kucing saya mengejar anjingnya". -nya is back to Andi.

[ImNasser]

for a moment i thought the cat had a dog then i realized its probably another person's dog

Is "... anjingnya dia" acceptable?

[Away54]

"... anjingnya dia" is not an effective statement but should be accepted.

Formally, it's incorrect.

[AkoSiKoneho]

Why the hell is it anjing dia? Why not anjingnya? What are we speaking bahasa pasar?

[Away54]

It's "anjingnya" now.

For "bahasa pasar": I don't know what Duolingo team want. Sometimes they are very strict with Standard form (bentuk baku) but sometimes they combine the lesson with Non-standard (tidak baku).

[TonyBerjaya]

Perhaps it is a Tiger, not cat.
