Robo,
I think I know what you are feeling. I am a dog man, always have been, always will be. I've had to put down two beautiful family pets, a Golden Retriever, Belle, and our first Pointer, Chula (in my avatar) within the last several years, and it nearly killed me both times. I hurt so badly, the only relief I got was writing about it here. So many CPFers are likewise dog people, and their words of kindness and consolation helped a lot.
After we lost Belle, I couldn't bring myself to get another dog for a solid year. I was being selfish and my family, dog lovers all, missed having one around. After we lost Chula, I decided to do it differently. I knew we could never replace her, but I now firmly believe that dog people need dogs and visa versa. We adopted our current girl, a Pointer rescue we named Mia, soon after losing Chula. We don't regret it a bit. We still love and miss Belle and Chula, and have many happy memories of them and the satisfaction of knowing we gave them a great life. But we love Mia, she loves us, and she is now having a great "dog life" herself.
The old cowboy said, "That's the trouble with dogs---you always outlive them". That's the hard part alright, but I have come to believe that the best answer is to just keep on loving, and owning, dogs. If along the way, from time to time, we need to help them by easing their transition to the next world, well, that's just part of our job.
Congratulations on your new pup. He will undoubtedly have a great "dog life"!
Andrew
