High Tech Pet Wall Tunnel

Collars aren't. I bought this because we live in the country. I didn't want skunks and other critters just walking in, BUT we have four ponds and the dogs go swimming when they're hot. I've only had a few months and one collar is already history, I presume because the dog went swimming.

The best thing we ever bought for our dogs....we have had regular dog doors in the past....they let in the cold, the weather and other critters and even people. We love this door.....it works great....the dogs go in and out as they please ....it was extremely simple to install and it keeps out the weather and other intruders. I would recommend this door to everyone.

Worked perfectly. Snapped in on each side, looks good, dog likes it. Had the door about a month, so I can't speak to .longevity.

The wall tunnel works good. It doesn't look like you need it, but you do. Its alot easier than building your own frame around the door opening, even if your in construction. Its just easier and avoids the extra time and hassle. For the price its a deal.

Good product, straightforward install, no issues. Basically it's just a piece of plastic formed to fit the dog door.

I was going to purchase this item from a different store but I found it here for a better price.
