Second dog. Big mistake?

[Weevee]

Hi,
We have a 3 year old male greyhound who we've had for a year. We recently adopted a 4 year old female lurcher but I'm worried we've made a well intentioned but terrible mistake.
Our grey is very placid and slightly aloof. It's taken him many months but he really relaxed into being a pet and is a joy to have. We both work and felt that adding a second dog would give him some company as well as encourage his "play" side which has been lacking a bit.
The lurcher however is a lot of work. She's awful on a lead which means that taking them both out together is difficult and she barks and whines and is very dominant. She's growled and snapped at him a couple of times and even more so when one if us tries to give him a bit of attention. He's so gentle he just gets a bit spooked and leaves her but now he's taken up residence by the front door and won't shift which is a return to how he was when he first arrived.
We've tried to keep them separate at key times (eating, sleeping, etc) but the lurcher whines, scratches the door and has an accident which disrupts the grey anyway.
He's totally freaked out by her and I'm heartbroken thinking that we've ruined his life.
Will it get better?

How long have you had your new dog? why dont you sign up for some training classes with her and get an insight into her behaviour from your trainer. The fact she barks and whines and will even wee when separated points me to believe she is a nervous dog, I would walk them separately for now and teach her not to pull, time alone with you will do her good and if she is reacting to other dogs when walking could well be because she is nervous. Why do you think she is dominant?

Yes, how long have you had her?

Ours took a while to gel and settle together. Its hard to watch a shy dog go backwards when you've made progress, but hopefully time and training will help? I found that jealousy of attention has to be firmly stopped. You decide who gets patted when, not her...
