"I do not have any dogs."

Translation: Non ho nessun cane.

[ltramaral]

In this case it was "nessun"; when do I use "nessuno"?

[nicoladc89]

When the following word starts with "gn-", "z-", "ps-", "i", "sc-" etc... (nessuno gnomo, nessuno zaino, nessuno psicologo, etc...)

What is wrong with "Non ho qualsiasi cani" please?

[marziotta]

"qualsiasi" works as a translation for "any" only in positive sentences, I think.

I have anything I need. -> ho qualsiasi cosa di cui ho bisogno, ho ogni cosa di cui ho bisogno

You can call me any time -> puoi chiamarmi in qualsiasi momento

[Chris123456]

That is very helpful - thank you

[konsuntier]

I think you cannot say anything in English in that sentence. It should be "I have everything I need", if I am not mistaken.

[valerieheath]

Why is nessun not offered as a solution then?

[tango-alpha]

Why is "qualunque cane" wrong?

[teodoraduma]

why didn't accept "cani" because is the correct plural of the "cane"

[jgbachand]

You are correct that "cani" is the plural of "cane," but "nessun" calls for the singular. Also, as for the question above, I know that we can use "nessuno" as the pronoun "no one". Here, "nessun" is used as an adjective (or adjectival pronoun, not being a grammar expert). So, I believe that "No one has responded," would be translated, "Nessuno ha risposto."

It accepted "Non ho dei cani" march 5, 2014

[Koolkaren]

Is that the same reason it marked me wrong for 'Non ho alcuni cani'? Is 'alcuna' also only used in positive sentences?

[konsuntier]

It markes me wrong for using the plural, although in english it says "dogs". Maybe in italien you have to use singular to express the same. (I do not have even one dog?)

[Archangelica]

I used cani too, and was told it was wrong.

[Chris123456]

I now have an explanation from duolingo support about this. "Nessun" is followed only by the singular. One to remember!

[konsuntier]

Thank you for sharing!

[Archangelica]

Thankyou, it makes sense to me now! :)

[jgbachand]

But why is the "o" dropped, and "nessuno cane" is wrong?

[Dorian.Z]

'nessuno' is a noun itself

[nicoladc89]

nessuno is a noun itself, Dorian Z is right... But, it used before others nouns, when nouns starts with "sc-", "ps-", "gn-", "z-" or any other consonant group except "pr-", "pl-" and sometimes "ps-".

(nessuno gnomo, nessuno zaino, nessuno sconto, nessuno sciopero, nessuno pneumatico etc.. )

[jgbachand]

Grazie, Dorian.Z It seems so obvious when someone else says it!
