Firstly, you are completely wrong, and it is stupid to make a thread like this when so many gorgeous adult greyhounds are spending their lives in tiny racing & rescue concrete cages waiting to be homed. Meanwhile the average person will skip out the door and get a bloody poodle mutt puppy from a puppy farm or deformed french bulldog puppy or some other genetic abomination that shouldn’t exist.
SECONDLY, greyhound owners do not let their greyhounds wander round off the lead in public, so it’s a completely moot point. Why would you get one? Because they’re a gorgeous, gentle, low-maintenance, clean, quiet, rewarding dog. They can run in a secure garden, rented dog field or deserted beach. They run for about 60 seconds and then are content to sleep on the sofa the rest of the day.
Kennels/rescues will advise you keep your greyhound muzzled and on the lead for at least the first 6 months to a year while they settle in and learn their temperament. The vast majority of greyhound adopters do this.
Most greyhounds are not a risk to cats. My boy doesn’t even bat an eyelid at them. Greyhounds are cat-tested at kennels and some greyhounds live happily in homes with a cat.
When there are so many dog breeds that kill other dogs and humans, this is a bloody stupid thread to make.
