jumps in
They are amazing and your set up sounds fine. My boy is 11 now - we had him as a bit of an older hound at 5. I love him to pieces. Obviously they are all different but I now have dozens of friends with greyhounds and they generally just fit in with your life. I have a 4 year old DS and they are fine together. My hound has never growled or snapped at anyone even when accidentally trod on/landed on.
We live in an apartment with limited outside access and my boy is happy with a half hour of so walk a day.
They can pull to start with - mine was very strong but he soon settled down. He also always had a very high prey drive - he did race for an awful long time though. He will still go on his toes a bit if he sees a cat/squirrel/pheasant. He has always been fine with small dogs but his recall has never been trustworthy enough to have him off lead. I do know plenty of people who have trained this but you can't expect to have one and loose it off.
Mine never barks. Some do but generally they are quiet.
If you are precious about your sofa forget it. Mine doesn't actually go on ours as he's scared of it after it 'reclined' on him but I don't know many people who have kept theirs off.
They are rubbish dogs. It is much more like having a giant cat. They won't catch a ball and even 'purr'.
They don't smell. Mine doesn't leave hair everywhere. They can get rather toxic wind but I find it depends what they're fed.
There are lovely greyhound communities all over the country that meet up for walks etc and a lot of us on Facebook.
They generally have crap teeth. They need looking after - even then you may find they need an expensive dental later on. Other than this they are a fairly healthy breed. Bone cancer tends to get them in the end.
They are very cuddly and loving and loyal although you are cuddling a bag of elbows.
They can be rather dramatic. The GSOD (greyhound scream of death) will terrify you at first and you will think they are going to lose a limb. They've probably had their toe trod on or ht their funny bone or something.
They can have sensitive tummies so they can take a bit of time to settle on the right food. It may well not be the cheapest either.
I find the boys more laid back than the bitches tbh.
They are totally amazing and the best dogs ever biased
