Neighbors had a elderly female dachshund and a younger male golden lab. When they came home one day, the dachshund had died in the back yard and the lab was standing over her. The next day, I walked by with my dog. The lab, who would normally bark at us, was pacing back and forth in the yard looking down. He did not want to eat and was continually crying. The put him on prozac for a couple of months to help him. No question about animals having feelings.
