Puppy training starts the day you adopt. The first 18 weeks are the most important for early command training and socialization to other dogs and to people.
Naturally fearful puppies and dogs can often learn to be more confident through controlled exposure and a program of desensitization and counter-conditioning.
Inventive management may lead to immediate results for some problem dog behaviors, but real change takes kindness, time and patience.
Modern dog behavior modification techniques are effective; dog training guarantees are not. Outcomes depend on factors unique to each dog’s circumstances.
Some cohabitating sibling puppies develop littermate syndrome because their deep bond interferes with normal socialization to other dogs and to people.
