I would'nt be without a dog flap in the back door - the girls tend to use it even if the patio door is open

I originally had a medium Staywell flap which was a fine size for Kaiya my cocker but as Trinity my collie got bigger, she was struggling to squeeze herself through it so we installed the large size and all the girls have no problem using it. It did'nt take them long to get the hang of it either.
The staywell comes with a template so you can work out how big of a hole you need to cut and we had no problem installing it.
Shop around first though - our local pet shop which is expensive at the best of times, was 40 quid more expensive than Argos
