Just because a dog lives in a kennel, doesn't mean it's not a family member. The kennel design of OP is pretty darn awesome, and anyone going through the trouble to not only design a kennel like that, but build it too, is definitely not somebody that doesn't care about his dogs. If I ever have the money left over to build kennels for the four of mine, I will do so because a kennel is much more comfortable than a crate!
So would some of you just back off and leave that guy alone? You are not helping!
To OP: please don't take offense by some of the comments and stay. I have a friend who just became kennelmaster for his unit undergoing lots of training with his soldiers before they deploy downrange. I truly appreciate what you guys are doing.
The dog is for his folks, who are building their retirement home in South America. Can't have any weapons, so the dogs are pretty much going to be purchased as a measure of security. And the son who does not own the dogs is going to build them a kennel for their dogs. Which is a little different. It does not mean the people won't care about the dogs, but it does come across like the dogs will be stabled during the day and let loose to protect the property at home.
Personally, I do not think it is correct that the dogs will not protect if they are not house dogs. I think dogs with limited socialization and human interaction may be a great deterrent, it is likely they will be territorial and bark at anything that approaches their fence, kind of like junk yard dogs.
There are some red flags here:
1. The OP has not owned the breed, but has seen them work in the service. That does not come close to knowing what it takes to raise, care for, train a GSD. They are not born fully trained.
2. The OP is buying the dogs for his folks. Are they on board? If they are, why aren't they figuring out how to house and care for the dogs? Late 50s is not aged. Nothing wrong with a son choosing to do something for his folks, but dogs are a lot more involved than buying them a membership to a country club.
3. The plan for the dogs is to be kenneled all day, and run loose at night to protect the property. It does sound like we are considering something that will eat and poop and shed, but not necessarily something that has a personality as intricate as a GSD.
