I am not sure on the going rates of Dogs/puppies but I would assume lowest pricing will be a rescue from a shelter or group. Which leads me to my next topic socializing.
I would say that most dogs will bark in homes out of fear and anxiety. Therefore socializing a puppy well will definitely help with any panic barking. I’ll label it panic barking in this context
Now with an adult dog we can’t look at socializing because they will be passed the critical stage. Therefore I like to tell people who rescue one thing “don’t rush”. Most rescues will be well passed the critical/imprint stage. Going slow and seeing if a dog fits into your family and environment is the best approach in my opinion.
Hope this helps a bit. Our
Puppy section might help a bit with socializing and how important it is for a well rounded dog.
