I will have a maximum of 4 Rottweilers. When two dogs become mature adults, I will get 2 new puppies that I will raise from the start of how to behave, and eventually replace the mature adult dogs when they pass away, or become too old to be reliable guard dogs. In the city of Pittsburgh, you’re not allowed more than 4 dogs, but considering I will have a 3BR+ residence, it would just make sense to not have more than 4 dogs in my home. Once the mature adults becomes too old to be reliable guard dogs, they will retire, and the younger dogs will take their place. I will still keep the mature adult dogs. They would have served me well, and deserve to have a good end of life years.
When the second pair will reach mature adult, I will get 2 new Rottweilers, and they will eventually replace the second pair. This will continue on until I am about to pass away. When I am at my end of life, I will surrender my dogs, so they can have a good home, and will hopefully pass away peacefully. I wouldn’t want my dogs to starve to death because I passed away.
