Last night when I went to turn his night lamp on, I found my Angus dead. He was approx., 12 years old. The only thing odd that we had noticed is, this past Tuesday I saw him with his mouth open and he threw up clear liquid. Only saw him do it once. He wouldn't eat 2 days later, just ignored his mouse. He seemed ok, moving fine, muscle tone seemed good, and then he was gone the next day. Any thoughts? He will be sadly missed.
