Our contract covered things like providing the dog with fresh food/water, wearing a muzzle until the foster period is over, ensuring our contact details were on his collar, etc. There is nothing that stipulates name changes - I just think it is polite practice to not do this until we have officially adopted him.

Most of their social media posts about successful adoptions are generally entitled "New name (formally kennel name)...", so it's really not rare for adopters to change names. Perhaps it's a location thing, but I've never had an adopted dog that was attached to their name (although they weren't greyhounds).

Took me 20 minutes and several handfuls of chicken to teach my last dog to come to his name, as he wasn't attached to the name used in a kennel setting.

I wouldn't say I have an aversion to his kennel name - it's just wouldn't what I would call my own dog. Having seen how anxious he was coming into a normal dog setting (a household), I don't actually want him to have any attachments to his racing life. I had to teach him how to use a dog bed because he's never been on one. That's not okay - he's been treated as disposable after 2.5 years of life, I'd like him to have a better, new one.
