I've never met a LHW, so I couldn't really compare the two. From what I've read, the LHW is a little bit more feisty while Silkens are a little bit more reserved. My understanding is that LHWs originated from a Whippet/Sheltie cross, where Silkens came from LHW stock, Borzois, and pure Whippets. I haven't spent a ton of time around Borzois but from the few I've known, they seem to have a pretty similar temperament. I think Laur summed it up pretty well - poised, regal, but fun and with a silly streak. My breeder has one that charms the pants off of me every time I see her. She reminds me of Rowan a lot. She comes up and just...
demands attention. "Here I am, I'm awesome, love me." She'll shove her nose into your hands and just wait all matter-of-fact about how you WILL pet her. She's just like a female Rowan. I want to steal her.
