I lost three dogs within a three month span. Robbie, a collie mix, died in his sleep at age eighteen (he was nearly nineteen) on Nov. 5th and we buried him near the front of the property by the fence line (he always loved to 'chase' the cars along the fence.)
Emily, my Rott mix, was only eight, when she died on Nov. 22nd. My neighbor checks on my dogs for me while I'm at work and Emily was fine in the morning and dead in her bed in the afternoon. My neighbor thought she was asleep until Emily didn't respond to her call. We think it was a heart attack and we buried her next to the house. She was my 'velcro' dog and always wanted to be wherever I was.
Patch, my beagle/terrier/? mix, almost made it to eighteen but I knew it was time. We took her to the vet on Jan. 23rd of this year, then took her home to bury her. We put her next to Emily, they were always constant companions.
This was their last vacation in NC (May 2005):
