The word SOCIALIZATION gets used incorrectly a lot. If you want to raise an emotionally resilient dog, then you need to understand what socialization is and what is not first.  Understanding socialization is the key to raising a dog that doesn’t bark, lunge, bite, snap, growl or hide. One of the biggest mistakes that puppy owners make is waiting or thinking that they have to socialize their puppy after he’s had all of his shots.
