When we bought this house, we made sure the garden was dog-proof. We have a high brick wall one side, and a sturdy fence and thick hedge the other. And yet, Bogie has found an escape route into next door's garden. I cannot find out how he gets through, they cannot find where he gets through, the man who cuts the hedge can't find out. But, if left unattended in our back garden, he ends up in their's. So, in spite of the hot weather, we decided to keep the french doors closed. So, he now jumps through the window. All this is probably because he once saw a cat in next door's garden and needs to check if it's still there. And I have learned that if he wants to sniff something when he's on the lead, it is better to be patient and let him satisfy his curiosity. Otherwise, as soon as he's let off the lead in the field, he'll turn round and rush back to check out the smell. And there is no hedge thick enough to stop him when he picks up the scent of a pheasant. Probably a cocker spaniel thing!
