Pam, both of my parents were like that when our Old English Sheepdog died young (health complications). Never again. It took a few years, but they finally got a an adopted Greyhound. And then 2 years later adopted another.
Now, since Scooby passed this summer, they are again saying that once Daphne is gone, no more dogs. I think that feeling comes and it goes. It just takes some time.
PS~It always warms my heart to hear of other pit lovers. They're such a misunderstood breed, it makes me so sad. I doubt I'll ever own another breed again!
