"The little dogs are eating."
Translation:Les petites chiennes mangent.
You can use the masculine noun, just the adjective must agree. "Petit" is masculine and must be used with "Chien" the masculine form of dog. "Petite" is feminine and must be used with "Chienne". Duolingo will accept either form, as long as they correlate. A general rule is that e after the end of an adjective is feminine, whil if there is no e at the end, masculine.
I agree with Lauren. That's what I was wondering about. Also Duolingo I find it very embarrassing sometimes that I can't delete my posts. Like right now, I thought my post was gonna go right under Lorens and it would make sense but it didn't and now I don't know how to delete it.
Either you need to fix this ASAP or I'm a huge noob who doesn't know how to delete a post or use their phone.
