Dog Training & Behavior Library
Clear, science-based guidance for raising a well-behaved, confident dog.
ErXing Dog Guide is a free, searchable library built for new owners, rescue adopters, and anyone who wants training advice grounded in positive reinforcement rather than guesswork.

Six ideas behind every guide
The articles cover a lot of ground, but they all rest on the same short list of principles.
Reward what you want
Dogs repeat what pays off. Catch the behavior you like and reinforce it right away.
Positive reinforcement basics →Timing tells the story
A marker, like a clicker or a quick "yes," shows your dog exactly which moment earned the reward.
How marker training works →Keep sessions short
Brief, focused practice that ends on a win beats long drills that end in frustration.
Structuring a session →Everyone uses the same rules
Mixed signals from different family members make learning harder for your dog.
Aligning household rules →Prevent before you fix
Manage the environment so unwanted habits don't get rehearsed while new ones are being built.
Common behavior problems →Read the signals
Body language shows when your dog is comfortable, stressed, or ready to learn.
Understanding body language →How the library works

Questions people ask first
Is ErXing Dog Guide really free?
Yes. There is no account, no paywall, and no sign-up. Open any guide and start reading.
What training methods do you recommend?
Reward-based training. We explain how it works and why, and we don't recommend punishment-based tools or "dominance" approaches.
Can these guides replace a trainer?
No. They are educational. For aggression, severe anxiety, or a sudden change in behavior, please see a certified professional trainer or a veterinary behaviorist. Read our disclaimer for the full picture.
Where does the information come from?
From guidance published by recognized animal behavior and welfare organizations. Every guide ends with its sources, and our methodology page explains how we research and review.
Where are my favorites saved?
Only in your own browser, using local storage. They are never sent to us, and clearing your browser data removes them.
Editorial transparency
Every article is written in-house, dated, and checked against our methodology and sources. We correct mistakes publicly — see our corrections policy. Nothing here replaces a one-on-one evaluation from a certified trainer or veterinary behaviorist, especially for aggression or severe anxiety cases.
