We're not sure what to do about it. She is breathing fine, but seems to have a little trouble drinking water. She doesn't seem to be in any real distress. We were feeding her some blueberries, and it happened then. She scared us for a while because she clearly seemed to be choking. Then it got a much better. she only seems to be choking now when she drinks. We took away her food bowl because we don't want anything else to get caught, but we also think something needs to unlodge it. We see a lump on the side of her throat. My son wedged her mouth open and said he sees it in the back of her throat. What should we do? Please help!
