I've had my older dog for 6 years now. I never had a pet growing up and she is by sanity saver. Besides being over-weight which turned out to be hyperthyroidism..she has never been sick. We put a gate up between our kitchen and living area to keep the puppy in the kitchen. She chews too much. When I came home from work yesterday I could hear the older dog whining really loud, she knew I was there. I opened the door and she came running out. She had the runs. Then I looked in the house. She had broke the gate down, and she was sick all over the kitchen. Mostly by the patio doors. She had the runs and threw up. (we shut the air off at night. All windows are closed!!!) She then went and hid under the deck like she does if she ever does anything wrong. I felt so bad, here she tried to get out and nobody was there. I spent the afternoon cleaning, washing floors. Atleast that is off my check list for this weekend.
