I am looking for a mature (18months +) part trained/trained labrador to be the family pet.  Must be willing to have long walks twice daily and be capable of being left alone for up to 4 hours without destroying the house!! We live adjacent to open countryside and have a secure garden.
Anyone with any info would be greatly appreciated, please phone 01763 838065 or email: john.black@ultracontrols.aero

If you mean trained/part trained to the gun - then trainers usually sell trained and part trained dogs.  Good luck
