Yup, they can get acid reflux. One of the dogs that I take care of on a regular basis has it. So I have to give him medicine 30 minutes before mealtime, and then he's isn't allowed to play at all or do anything for an hour afer he eats so help keep his tummy calm. Sorry I don't know too much about it, I just know that it is possible for a dog to get acid reflux.
