We have underwire fence so dogs wear collar for the fence will these collars interfere with the dog door collars?

My dog wears this collar as well as the collar for a PetSafe radio fence. There is no interference between the collars. One is radio, the other is sonic. I am sure the sonic collar (this one) would not interfere with your underground wire fence collar.

I bought an electronic doggy door 2 years ago. The replacement transmitters I have bought are no longer available. Will this one work?

Ours is about 2 1/2 years old and we didn’t have any problems getting it to work with the older door. We just put batteries on them, then put them on the dog, and we haven’t had any issues with it.

Does anyone know of a smaller sensor that will open this door? The sensor is big for my dogs neck. It’s okay for my bigger dog.

No I have not found one. I love the way the High Tech product works. I would pay more money for a sensor if it was smaller. My dogs are 8 1/2 and 12 lbs.

When inserting new battery what color should the light be!

Red,are you using the new style battery from the mfg?
