"The dog is not scary."

Translation: そのいぬはこわくありません。

[Pinni10]

The sentence did not state 'that dog' so I got it wrong!

[Krowassan]

Yeah. It's getting annoying that the rules that the app sets up to follow drastically are suddenly dropped

[Arrekin]

But it stated 'the' what suggest using この、その、あの

[nikkox]

Why not using usual 'kunai desu' form ?

[noooooone]

There doesn't seem to be a big difference in meaning. Maybe くありません is a bit more formal.
I too thought that くないです is more common, at least in spoken Japanese.
Google it, lots of discussions out there... :)

What do you mean? The formal negation of an い-adjective uses the くありません form.

[Yuki378850]

Would こわくないです be the same as こわくありません? Is there a difference?

[catlinbelle]

As far as I understand, 怖くないです is less formal, while 怖くありません is more polite. But they mean the same thing.

I thought arimas was for non living things....

[XRavishX]

It's just a negative form of こわ.い Drop the い and add くありません. Thus, it doesn't have anything to do with the dog.

[V2Blast]

The formal negation of an い-adjective uses the くありません form.

[SariniLynn]

Maybe this is more like "there is no fear" rather than "there is no scary dog"?

[AndrewCott12]

Yes i thinkmy Japanese teacher told me this as well

[Karo706653]

How would one express, that the dog is scared in comparison to scary?

[Akira386]

犬がこわがっている

[Sofia701655]

I wrote いぬはこわくないです　and the correct answer it gave me was いぬはこわくない. Was I too polite, or not polite enough then?

[V2Blast]

I think it should have accepted your answer. Report it next time.

その犬は怖くないです。　was marked as wrong??
