Thanks for all the feedback...

I certainly wouldn't remove water but what I'll try is picking it up before bedtime. Ben has access to it at all times during the day and in the evening but tends to follow whenever I go to the kitchen and has a drink (That's if he can prize himself from the sofa).

When I make a cuppa tonight, around 9:30ish I'll pick it up after he's had a drink and see what happens. He doesn't need the garden every night but I would like to get him to go right through.

As far as the "Dog Flap" I'll be happy to let him use it once he's settled in and have been training him but as yet the penny hasn't really dropped.

Not sure about "Crates" and don't know if he would take to one and there seems to be for and against on here.

Cheers all,

Dave
