I've had a lurcher/terrier cross now for 6 years, and other than his first year, he's always been alone. The dog we once had, Jet, a little terrier around 12, attacked Ben (6 y/o dog) one day for no reason at all after spending a year with him, both got on as good as a gold and he was great with Ben when he was a puppy. When he attacked him, we tried to integrate them back together and hope it was just a one off but it wasn't. Jet sniffed Ben's rear and then attacked him which I believe has scarred Ben mentally.
Now our new puppy - note we put Ben first for everything to make sure she knows he's top dog -, Bonny is a 16 week old Doberman/German shepard cross and absolutely adores Ben, but whenever she goes within 2 feet of Ben, he growls and snaps. When they first met it was Ben chasing her around, but now it's been reversed. Ben is absolutely fine with her being around the house, shares food, sleep on the same bed etc. But as soon as she goes near him to play or smell he snaps and growls and I'm thinking this is due to him being attacked when he was younger. Will he change in that sense? If so how long do you believe it'll be?
