ComsmartSmart Wireless Dog Door Bell, Doggie Doorbell for Pet Potty Training Communication Go Outside Press Button with 38 Melodies 4 Volume Levels LED Flash (1 Receiver & 2 Transmitter), White

Showed my puppy it a few times and by that night he was using it. Day 2 - he would go to door & I said ring the bell & pushed it with his nose. This is a definitely a great purchase !!

We are still training for consistent use, but our 6 year old pup picked this up pretty quickly and it's cut down on scratching by the door to be let out.

Great idea for letting my dogs in and out. Never know when they have to go. Now they can tell us!

Works amazing! My dog started immediately using it and the sounds is loud enough to hear anywhere. Only thing I would say is they are pretty stiff. You have to really push down for it to ring. Other than that it works amazing.

Works as intended. My last set of door bells lasted a while until moisture corroded the batteries and I side of the door bell. Cannot complain with pnw moisture.

this product is one of the best purchases I have ever made for my puppy. He is 5 months now and has learned how to press it legitimately now, and I definitely recommend this product. It is so sturdy if applied correctly, and I am gonna move soon and buy another one

So it's nice, it does what it say, kinda wish the part for the dog wasn't as hard to push but it does work. Has several tones to select from.

I love it when it works. I have a smaller pup and I see him hitting the button but because the rim around the button is high it doesn’t activate the bell unless his paw is perfectly centered on the button . Maybe not a problem with a large paw.
