My rabbit passed away yesterday morning very unexpectedly - he turned a year old only a week ago. He was behaving normally the night before, and even that morning a few hours before we found him he seemed normal. It's worth mentioning that he just experienced a long drive and move into a new house earlier this week. I tried my hardest to do some research on if the stress of the move could've done anything, but I haven't found much. This was the third time he's relocated, so its definitely something he's used to. In this new house we have a roommate with a large dog, which the bunny was introduced to once. Once again, I tried doing some research on whether the stress of living with a dog could've caused his early passing, but didn't find too much. When we found his body, he was flipped on his back (belly up) and there was some bile on his mouth and neck. Did he eat something he wasn't supposed to? Really any insight on what could've happened would be greatly appreciated.
