Dog's Belly on the bum??

Hi,
MY dog for the past few days has been outside eating a little grass here & there. Today my husband was home with her- and let her out, and noticed she ate some more grass and Vomited too. HE said she is acting OK, running around outside & playing with him....but she still goes back to eating the grass. My Mom thinks maybe her belly is on the bum, which is why she is eating the grass. I will take her to the Vet if she throws up more and continues to eat the grass (by tomorrow afternoon).
What's your opinion????
Think she is OK??
thanks for reading & writing back.

 

I, too, think this may be a sign of tummy upset. It cold also indicate worms. Have you noticed if the stool contains any visible worms?

 

Well, Hopefully its nothing...and she will be feelign better soon!
I didn't look at her stool- but I will check it later on when I get home and she goes.
Hopefully its not worms. How would she get it? I mean, she is an indoor dog. Doesn't eat anything raw or gross....
But ya never know. I will look into it.
Thanks for your time & help!!
