My 5 year old boxer has been getting an upset stomach lately quite often. She will suddenly start licking her lips real fast and want to go out to eat grass. She usually stays outside for a half hour to an hour. This can happen multiple times during the night. The vet says to give her a Pepcid AC when it happens. I haven't done that yet. Does anyone have any other home remedies? Is this known to affect boxers very often? For the record she eats about 2-3 cups of Acana Prairie Harvest dry dog food a day. We don't give her any table scraps, but we do give her an occasional liver treat.
