Hi Guys, Need info or recommendations about electro-magnetic DOG doors. I have Googled until I am blue in the face and the only fairly reasonably priced door big enough to handle Sissy's dogs is the PetSafe Dog Door. That one has batteries in both the collar key and the door and Steven (Son-in-Law) says the batteries go bad really quickly in the winter -- and that's in PHOENIX! Up here in the mountains, I would have to be replacing the batteries every other week!! The door we had in Magnoliaville had batteries in the door but the collar key was just a magnet. Problem is this was for cats or small dogs. The door battery lasted for at least a year and was not affected by the temps. I have not found a similar door for larger dogs and I don't know why. I'm thinking that the type of magnetic latch is maybe not strong enough to keep a large door locked. The door Sissy has takes about 5 or 10 seconds to recognize the collar key, then makes a clunking noise and releases so the dog can go through. When the flap comes back down after the biggest dog goes through, it does not latch right away but swings back & forth several times. THIS is how Cheeto managed to escape and get lost -- he learned to wait for the flap to swing and then he would duck out. I want a door that has a strong enough magnet that it latches immediately but I DO NOT want to have to spend hundreds and hundreds of dollars. The one we got for the kids cost about $240.00 and the
*&*&^$&^)*& cat *still* managed to get out and get lost!!! SO -- does anyone out there know of a magnetically locking large size dog door (opening about 12" x 20") other than the PetSafe model that costs in the $250.00 range? I haven't found one in hours and hours of searching so will be grateful for any info you might have. CiaoMeow >^;;^<PAX, Tia Mary /\___/\
