Long night for Sydney

Sydney got sick last night - 2 sessions of vomit - 2 acts of vomiting in each session. A total of 4 vomits I had to clean up last night. (BTW, Resolve carpet cleaner for pets works great for getting the stains and odors out of the carpet). I took them walking about 7:30 pm, almost 2 hours after they ate. We were walking at a pretty brisk pace and Addy was superexcited about walking. I had to cut our walk short - only about a mile and a half - because 1) it was starting to get dark and 2) Addy just would not slow down.

Sydney didn't show any outward signs of wanting to slow down either. She would grab some grass as we went along (dogs will sometimes grab grass if they feel nauseated to make themselves throw up) but she will eat grass every time we walk - usually without the vomiting. It was maybe 30 minutes after we got back did we have Session #1. Session #1 consisted of all of her dog food, non-digested. She laid down and fell sleep. She was definitely lethargic. About an hour later, she got up and played with Addy - Session #2. Session #2 was more bile - she threw up her dinner in Session #1. After Session #2, I gave her the prescription medication the vet prescribed (yes, we have been here before). It seemed to help her b/c she slept threw the night without incident...

...or so we thought. We were getting ready to put Sydney in her cage this morning when we found another pile (could this be Session #3). We have no idea when it happened...

I have to add that my husband did not, nor never does, clean up the vomit. He apparently gets 'sick' when he is around it. What does he think happens to me?
