Dwayne,
Very sorry to hear about your loss. This is Bela who my wife and I lost back in December:
Seems like a similar situation to yours. Bela always liked my wife, but she had a level of devotion to me that did not exist with anyone else. We have two other dogs and they didn't act right for at least a month after Bela was put down. I didn't even want to be in my house for several days after it happened. Our home just felt empty without her.
All I can do is speak from experience and say it does get better with time. I can look back and realize I was fortunate to have Bela for the time I did. Sorry for your loss.
Matt
