Thank you for the messages of support.
Doganjo - I always read with interests your posts and clearly you are an experienced dog owner with a great involvement in the world of dogs, however, so am I. I am not going into my own personal circumstances and in an ideal world I would keep Orla - however, I know my household circumstances and it is becoming a liability now - one or both of the dogs is going to end up getting really badly hurt - indeed my oldest bitch who is nearly 10 was lucky not to have got blinded on Saturday . I have made the difficult decision to rehome her - we have been managing this situation for over 2 years now and there is no practical solution as I have tried them all. I cannot let my young children (1, 6) live in a prison - we only have one door to the house and at the moment I keep it locked to keep the dogs apart but it is a fire risk for a start. I do have kennels which the dogs go in during the day when I am at work but they are pets - not outside dogs and should be and deserve to be in the house free from stress.
I love Orla, as I love the other 3 of my dogs - it is for that reason I want to see her go to a home where there is not the threat / or the stress for her. Fortunately my friend, who is her breeder, is going to have her back for a trial period. If anyone reads this and thinks they can offer a home then please PM me. But please don't add your two pennyworth to what has been a heart-breaking, difficult decision. I posted on here with the hope of finding a loving home to what is an absolute gem of a dog.
