This dog house is so cleverly constructed, that it was a pleasure to assemble. The material feels good and is very sturdy, and does not smell (like some of the wood houses). The house looks great, and my dog took to it almost immediately. The X-large-size house is the perfect size for him (55 lbs.) but might be too small for a larger dog.
I have four rescue dogs ranging from 45 to 65 lbs. and bought each one their own dog house. It gets pretty hot here in the summer and the winters can be below freezing as well. I ordered the large size based on recommendations from others, but may have been able to use the medium as there is a lot of extra space in the dog house. It took me about an hour to put the first one together and then 20-30 minutes for the second one. I plan to do the other two today. Here are the areas I had a little challenge with putting together. 1) Getting started - I'm left handed so diagrams always seem backwards to me. The instructions are almost entirely in pictures, which is great once you get the first few pieces together, but difficult to try to orient the first three. 2) Piece #11 for the floor is a little tricky, but after the first one seemed a little easier. 3) The diagram shows connecting the top of the door piece (green) to the top front panel, but I found it easier to put the door piece on top of the door and then affix the panel (gravity helps here). 4) The roof panels are also a little tricky. They are also tongue-n-groove, but I can't get them to fit together tightly so the last panel doesn't fit snug and leaves a 1/4" to 1/2" gap. Also, to slide the roof panels on, you have to lift them a bit in the center. I'm going to ask a friend to help and see if we can get the roof tighter. It's not a big deal as in the summer I plan to slide some of the roof panels forward to provide more ventilation. Other than that, if you can count, you can put this together easily, and without tools. I do highly recommend following the directions of laying out all the pieces in number order first - makes the rest so much easier. If it weren't for the roof panel issue, I would have rated the quality as excellent. Just felt these should snap together as easily as the side panels do. Yesterday it was mid-70's during the day and dropped to the 40's overnight - so I tested the dog house temperature at the heat of the day and it felt cool inside (yes, I did climb inside!). I also tested it at night and it did not feel drafty or cold. I really like these and think they will work well for me if the dogs use them. While they have individual kennel runs with covers, I wanted them to have a place to get out of the wind or direct sun and these will definitely provide that. So far they haven't used them, but I can't control that...at least I've done my part in providing that shelter...the rest is up to them.
Ordered the jumbo size for my great dane pup. He's now 1 year old and has plenty of room. His height gives him a lil difficulty getting out, but for the price and size im happy. I went with this model because he has allergies to pine and other soft woods. Easy assembly. Each piece has a number on the end which is difficult to see at first. Lay out all the pieces in numerical order and assembly is a snap. At first he wouldnt go in so my wife crawled in to get him in. My other dog (shepard, rott mix) promptly crawled in with her to give an idea of the room inside.
