My dog is rubbing her mouth and won't eat dry food. What's wrong?

Updated on September 23rd, 2025

My Australian Shepherd is acting funny. She is drinking a lot of water. She won’t eat her dry food but did eat some rice and chicken that I made her. No vomiting. She’s rubbing the underneath of her mouth on the carpet. Should I be extremely concerned?

I'm sorry your dog isn't doing well at the moment! It's good that she isn't vomiting, but I understand why you would be concerned that she isn't eating her normal food. There could be a couple of reasons why this is happening. Given that she is rubbing the underneath of her mouth on the carpet, it could be her mouth is painful. That would explain why she won't eat the dry food but will eat something softer such as chicken and rice. She could have a dental problem causing her pain, such as severe gingivitis, a tooth root abscess, or a broken tooth to name a few causes. It could also be that she is feeling nauseous and the chicken and rice is the only thing that settles her stomach. I would monitor her for now. Just offer her the chicken and rice tonight, but try the dry dog food again in the morning. If tomorrow she is still refusing to eat her dry food and rubbing her mouth on the carpet, I'd make an appointment with the vet for her to be seen. Best of luck, I hope this helps!
