Not being funny mate, but do you have the work for 3 adult lurchers. reading between the lines i would say that the dog must be a bit of a handful. Work and lots of it might sort it out. If you have the work for it then take it on, but if you dont you will only be continuing the cycle.
This is not a dig, mate, i like many others would only want whats best for the dog in the long run.
