Greetings from Gainesville, Florida!
You are smart to do all of the research you can before actually adopting a grey.
We adopted our first GH in December. He has been absolutely wonderful!
Even if you've owned dogs before, the books on retired greyhounds are a must. It's important to know the routine, the lifestyle, etc that they have had in their past life before they come home to you to be your pet.
Our dog came to us straight from the GPA kennel at the Derby Lane race track in St Petersburg, FL.
Living at the track for most of his life, there were many things that he had never seen before when we brought him home. The biggest one...shiny wood and tile floors. It has taken him a while to get used to walking on these slippery kinds of floors, but he's made major progress in the last month. Some dogs don't have a problem with this, ours did. Every dog is different.
Our GH has been extremely well behaved. He's never chewed up anything in the house, he learned the whole housebreaking thing in 2 days, he is gentle and loving with our old-man whippet that we have, I could go on forever.
This is the 4th diff dog breed that I've owned in my life and I can honestly say that it's been the best. I can't see myself ever having another dog besides greyhounds. We absolutely adore ours, and can't imagine life without him. Definitely meet and spend time with as many GH's as you can before making a decision.
Good luck!!
