Dog behaviourist/trainer West Midlands

[puggirl]

Is there any one who has any experience of using a dog behaviorist or dog trainer in Sutton Coldfield/WestMids?
We got a new Rescue dog on Friday and our 8yr dog will not accept her. Lots of barking, pacing around and trying to nip her back legs. The new dog has settled down just fine. We are showing the older dog lots of affection so she doesn't feel pushed out but it's driving us to distraction. It's been a rather stressful bank holiday!
Desperate measures but I think a behaviorist or trainer could be the only solution if we can try to keep the new addition.
Help would be very much appreciated.
