doggy door question!

[jiml]

I have seen doggie doors advertised that only open in response to a control on your dogs collar>>>

i have the petsafe brand.

Probs you may have is the door unlock mechanism is a little loud. and the flap is a hard plastic a little harder to train.

That said, I bought the door do to the concerns w squirrels and such as they are frequently by the door because my wife feeds them. I purchased extra magnets for the door and have never needed to use the locking mechanism. the squirrels can not push it open even when its not engaged.

they make great dane/saint bernard sized doggy doors dont they? yeah, i know i have shelties, but with the fostering and my love for bringing home dogs.. you never know what i will bring home!>>>>

the one I have is the large. It works fine for my 80lb coonhound and my mothers fat and very large Lab. St bernard may be pushing it?
