He has had it proped open all day and tonight I have been sitting one side of it with the box of treats getting very excited calling him in but he just looks at me as if im mad ! Im sure as you all say it just takes time, as long as he has mastered it by the time the cold weather comes, I dont want it proped open for to long !!!
My lurcher (who was about 25" at the shoulder at this stage...) used to fit through the dog flap designed for whippets (who should be 18" at the shoulder)
He had gone through it from when he was an 8 week old puppy, and saw no reason why he still shouldnt fit through
Thanx everyone, after lots of treats and an evening of myself and the other half calling the dam dog from either side he now well and truely has the hang of it. Its so nice to see him in the garden whenever he wants. You were all right just needed time and to see him mummy and daddy to look like total prunes first !!!
