We have had ours for years and our rottweiler loves it. He stays in it all summer, it keeps him cool. and in the winter we put cedar chips in and he stays warm. He also comes inside of course.

Pros: enough room for a 100+ dog

Cons: none

These have no insulation and no ventilation.
They keep the rain and snow off and thats about it.
They can be absolute sweatboxes in the summer.
We have some donated to our shelter which we do give to people who dogs have no shelter.... as its better than nothing...

Pros: Lightweight, inexpensive, easy to find

Cons: Hot in the summer and cold in the winter

I am so against igloos doghouses, unless there's no other option.

Pros: Provides shelter

Cons: Dogs should be in the house - unless there's no other option

great dog house we have a few of these keep your pet dry and warm in wet or cold weather

Pros: comfortable

Cons: none

Dogs love it lots of room put in a blanket or some hay to keep them warm.

Pros: Great for the dog like these instead of the smaller ones

Cons: Price is high but worth it
