A dog sounds possible...
Don't discount rescue greyhounds, some have bags of personality and are incredibly comedic creatures, very capable of learning all sorts of things.
And some are not, have been seriously 'institutionalised' and either can't really be brought out of that or the owner doesn't know how/know that they ought to (it may suit them to have a very quiet, unchallenging dog!).
I'd recommend making a list of attributes you really must have, ones you cannot tolerate and then refine that with the negotiable stuff.
Then see which breeds meet those requirements.
Then go and meet some of those breeds, and ideally, meet them at a breeders house (yes even if you're not intending on getting a puppy) - so you get to see what this dog is like inside a normal house, vs inside a huge hall or outdoors, at a dog show.
Then look at specific breed rescue, the ones typically run by the breed clubs for each pedigree breed tend to be the best and dogs will come to you direct from the prior owner or from a foster carer/original breeder, so they'll have been with people who know the breed.
That way you can potentially get a dog with a very well known history - however any rescue dog will take potentially 6 to 12 months to settle in so prepare to make some pretty big compromises on what you do/how you live for that time. You may get lucky and they'll slot in and settle much sooner, but it is better to prepare for the worst really.
