Thank you,

There are a couple possible causes.

1. Gastrointestinal upset, nausea, and abdominal pain can cause them to lick the air. Since she is eating grass every morning, and vomiting, then this would be a likely cause. The next step would be to figure out what is causing the abdominal upset.

To reduce acid in her stomach, you can try giving her the human stomach acid reducer, "pepcid." Give 1/8 tablet, per 5-10 pounds, every 8-12 hours. If that does not work, she will need to see a vet. She could have a gastrointestinal bacterial or parasitic infection. Usually this can be diganosed with a fecal test. She is pretty young to have metabolic disease but conditions like kidney disease, and liver disease, can cause nausea.

2. Another cause is seizures or neurologic activitiy. If you can get her to stop licking the air, by yelling at her, then it is not seziures. If they have seizures, you can not get them to stop no matter what you do.

3. Obsessive compulsive behavior can cause this as well. If you rule out medical causes, she can be put on an anti-anxiety medication like "prozac."

4. Dental pain can also cause them to lick the air. While she could have a fractured tooth, I would not expect too many dental problems in a dog her age. Just in case, take a flashlight and look around her mouth for redness, fractured teeth, bad odor, swelling, foreign bodies, or anything that looks abnormal.

I hope this helps. If you have additonal questions, please click "reply." thanks
