Why does my dog shake his head when I ask him a question?

he doesn't like the sound of your voice maybe too high pitched and hurting his ears try toning down

first of all, do you really expect you dog to answer a question?

secondly, if your dog is contantly shaking his head, it could be the signs of an ear infection.in that case you need to see a vet.

Shaking his head is either a sign of ear mites or an ear infection.Get him to the vet to be diagnosed.Unless you really think he is saying :I don't know.." LOL

May be you asked him a physics question and he didnt know the answer.

Ask him a botany question, he graduated and took phd in botany from the university of Koothatukulam 2 years back.

maybe he sees other people answering questions by shaking his head 2 u and copies them ( unlikely though )

well its quiet common that head shaking means no

so i guess the answer to your questions is No.

he likes the sound of your voice in question form. Mine does it too, It's the excitement we put into our voice when asking a question. My dog loves it when i talk to her, and it seems as yours does too.

Animals are much smarter than we give them credit for, maybe your dog understands more than you think : )

Because he like questions about "pussy"cats.he's gay!
