My 3 year old female dog was spayed a almost a month ago, about 2 weeks ago i noticed this really loud gurgling noise coming from her stomach. I thought it was because she hadn't been eating the same, but its been going on for two weeks now. It usually stops after she eats, but i know she ate her food twice yesterday. She acts like her usual self for the most part, just the growling and gurgling stomach, but she has been trying to eat more grass. Should i take her to the vet asap???
