Damn. That's awful. How do you communicate to a beloved pet that the surgery and painful treatment are attempts to make him or her feel better? And, animals are so damn perceptive that they know beforehand they are going to be put down. How do you deal with your bestest companion knowing you are going to put him or her down? If they were not so sick, would they run away or do they know it's for relief from suffering and are grateful? I have read that dogs do not think ahead, but don't really buy that because they think and have emotions and miss us when we are away and expect us to return and that's thinking ahead, right? I have also read and believe that dogs' souls are unconditional love so I guess when you are able, you have to find another loving soul to receive your love and give you love.
While the Dr. Doolittle movies do not touch on this area, I would so love to be able to understand what animals are wanting to communicate to us. Maybe that's the miracle waiting on the other side of the Rainbow Bridge.
I am very sorry for your loss. I hope it helps a little that we have you in our thoughts and prayers for comfort. Tom
