Our dog house
When the puppies are old enough (usually at 5 weeks) they need more space and outdoor activity. I am personally not in favor of raising puppies indoors in the living room.
Some breeders promote that type of breeding and claim that because of this the puppies are super socialized. My experience is, that you can have well socialized puppies and a decent living room! Puppies need to be able to run, have fresh air and they need to be able to play outdoors and when the weather is not nice to be indoors.
Our new dog house is easy to clean and has its own heat pump. The puppy box has in addition a heat plate, so that the puppies have the highest level of comfort.
The dog house and puppy run is directly next to the house and the terrace. From my office I am able to look into the puppy run.
