Oh no! I'm so sorry and praying that Princess just has a bit of colitis instead of pancreatitis. It's nasty stuff. My yorkie had it in June and it took a long time for him to get back to normal. We were able to give him sub q fluids at home, which really helped his recovery. BTW, it's pretty normal for the fluids to drop down under the belly like that before they're absorbed completely. We used to say Scooby had "man boobs". LOL
Did your vet do the cPL test that is sent out to IDEXX? Please post when you get the results. I will continue to pray for a fast recovery.
