My dog is basically in the middle (Sorta) of her period and ever since she's been trying to mount me (on my arm because she can't reach anything else LOL) and gnaw me on my shoulder or anything else. And if I don't crouch down or sit down so she can mount me she'll bark/whine. About twenty minutes ago she tried to bite my sister in the face when she was only petting her. My sister does not tolerate her mounting so this is probably why she tried to bite. She's about 8 months old-- Somewhere around there. My sister also says that we can get her ''neutered'' (i'm sorry i dont know if that's the correct word usage for a female dog, i know it is for the males) and I don't want that especially for my dog being so young. I honestly don't know what's wrong with her? Please help.
