I've owned 15 borzois over the last 24 years but I won't have another, I've moved onto the easier, smaller version the Silken Windhound.
Anyway, borzois - although they were bred for endurance and speed, trotting along beside the huntsmans horse waiting for wolves to be flushed out then with enough speed (and courage) to catch and hold the wolf, most are quite happy with a quick top speed blast around a field. They must run free, they get so much enjoyment out of it and that's where the enjoyment for the owner comes in too, the sheer thrill of seeing them race around :-) Once adult they'll walk any distance with you but a spin round the field is the only thing that tires them out. Even my last old boy who was almost 11 and had CDRM was still walking for an hour the week before he went to the bridge, albeit it slowly with much stopping to admire the grass growing :-)
Borzois are wonderful dogs in the house and if you own your own land, they are loyal, unassuming, affectionate in a gentle way with their owners and just tend to ignore other people. They always know when you're sad and will come and lean a head in your lap, they are very sensitive to their owner moods. You never need to shout at a borzoi, a disappointed tone is enough. They are extremely clean and easy to house train, even as pups mine very rarely ever had an accident in the house. They don't really need training, they tend not to pull on the lead, they love to wander along beside you off lead and they will always come back - unless they are chasing, then there's no point wasting your breath :-) They will happily spend 23 hours a day sleeping. They will squeal like they're dying if they stub their toes, but would run with a broken leg after a rabbit.
So that's the positive, now the negative. As with any sighthound they have a strong prey instinct, male borzois can sometimes transfer this to other dogs. They're not aggressive as such but will hunt. They need off lead running so the owner needs to provide a safe (for the dog and society) place for this. A borzoi can very quickly cover a field after something it sees in the distance so fenced off lead areas are best and the borzoi owner learns to constantly scan the horizon looking for hazards. I don't own my own land, and I enjoy walking in different places but it was never completely relaxing with a borzoi, even the ones with really superb temperaments did sometimes get themselves into bother.
I have many tales of times when a young zoi ran off after something it shouldn't. All in all though this in itself wouldn't put me off having another as that's just a fact of owning a sighthound. My last boy did not have a great temperament, or rather he probably had the typical temperament of a borzoi in the Czars day, brave enough to take down a wolf and with a very strong prey drive. Mr Beastly as most people on here would know him had me in tears on many occasions and was threatened with the bullet more times than any dog should ever be. He would hunt anything that moved, which made walking extremely difficult and not at all fun. He always wore a muzzle, even in his last weeks, as he could never be completely trusted with other dogs.
Of course you can get a dog with a dodgy temperament in any breed, but when that dog is 35" at the shoulder and 45kg of solid muscle with a huge teeth it becomes a problem and that's why I won't have another :-(
