Yes, there is a difference between knowing they are ailing and not going to live much longer and a sudden death. Our last two dogs died suddenly, one from a rare form of cancer that caused seizures, and the other from bleeding liver and spleen tumors. Both had a sudden onset of symptoms and were gone within two days. Our two cats were well into their 20s and told us when it was time to let them go. It's never easy no matter what the circumstances.

We currently have two dogs; Peanut, an 11-year-old Queensland Heeler and Spud, a 5-year-old Miniature Poodle. And dogs do grieve the loss of a companion dog. Peanut was depressed when Archie died, just as Archie was depressed when Merle died. Having a dog companion, I think, helps them get over it. Peanut perked up after Archie died when we brought home Spud. She treats him like her child - they are so funny! They are extremely bonded, and Peanut is very protective of Spud, even though she sometimes gets mad at him for stealing her toys!
