We LOVE this dog house. It is seriously adorable. I have 2 Shelties - 1 is 23lbs and the other is a puppy currently at 13lbs. There is plenty of room for them inside and to veg on the deck. I did purchase the spray sealant and sprayed all of the wood. I was able to put the house together fairly quickly with the help of a 10 year old! The step is cute but very narrow so my dogs just step from the ground to the deck and not touch the step.
