You have to keep your dog safe. If a prong collar will keep your dog safer than no prong collar, than go for it.
I try to have an outdoor kennel for each of my dogs. I am STILL down one since I separated the puppies from the dam, and so now Babs is in the house 24/7, This, in my opinion is not ideal. I love for Babs to be in, and when I am there she generally is inside, but I think they do very well having outdoor time as well.
A well-constructed, secure kennel in a fenced yard can be safer and more comfortable for a dog than leaving the dog the run of the house. For one thing the dog can drink and potty at will, rather than trying to hold it, or keeping to a schedule, which can, if there is a traffic jam or something, cause the dog discomfort or to have an accident.
My dogs rush outside to their kennels and go into them without any hesitation. It is a part of their life, and they do not find it onerous. There are other dogs in kennels there as well, so they are not totally bored out of their minds.
