Here are dogs who growl and snap when approached while chewing a  toy, eating or lying on a favorite spot. This is guarding what the dog considers to be a valuable resource. That's why this type of behavior can be called "resource guarding."

Possible Cause(s):

Some dogs are prone to this because of temperament tendencies. Others have learned to be this way. For example, if he has been
"attacked" by humans after he drops something such as a shoe. How, then, can he prevent your wrath? Dropping it didn't work.
Some dogs will then choose aggression in an attempt to back you off. This is painfully familiar to many owners. This behavior
can be a part of a general confusion about who leads and who follows in the home.

We Recommend:

First of all, remove anything he may protect. If you can't remove it (like a bed or couch) block access to it by closing a door or putting up a gate. Keep him on lead in the house so you can more easily control him.

Teach him to "Leave It" in a positive, fun way Do NOT make this into a battle. Make him think this command is an opportunity for a reward, not a chance to lock horns with you. Always start teaching this command with boring objects so that praise and treats will be the obvious choice.

Reward Spitting Things Out
Much of this sort of aggression is man made. People get angry when their dog takes things then fail to give him a way to please them. They create a situation where, once something is in their dog's mouth, there is no way for the dog to win. This can force the dog to start defending himself.

Here's the rule: Once something is in your dog's mouth, it is TOO LATE to teach him not to take it. The only thing you can teach him now is to spit it out promptly. Therefore, reward spitting it out.

Take then Give
Early on, practice "Out" with your pup. Walk up when he is chewing a toy. Say "Out" and take the toy. Praise him for his brilliance. Give him a treat. Return the toy and leave him alone. A few weeks of this once or twice a day and your dog will want you to come and take him toys.

Neuter him!
The most serious bites come from intact male dogs. Make the appointment today!

Ignore him!
Do not look at or speak to him unless he is working for you and even then, keep attention short, sweet and intense after which
you ignore him again. You want him to want your attention, not constantly be getting more of it then he desires. Leave him
wanting more.

Redirect him
If he is pawing you then keep him on lead and work his demanding self. Every time he paws you have him "Sit, down, Sit, down -- come, stay, OK" -- with little praise. He may well decide that a nap is a better idea.

Teaching him to move out of the way will help with his understanding that you lead and he follows. If it is safe to do, simply shuffle your feet into him (no kicking) until he moves then praise him. Or leave a lead on him and guide out of the way then praise.

He owns nothing!
He has no "favorite" chair or toys that are "his"; everything in the house is yours. If he is protective over anything, a bowl or a toy, remove it until his attitude has improved.

All of this time must be spent on the floor. The higher up he is in the room, the higher up he is in his head. Nope, his place is on the floor. Teach him to get off things on command. Always praise him cheerfully for obeying. If need be, close off rooms and/or leave a lead on him so you can manage him more easily. Always praise him cheerfully for obeying -- that is important!

Confine him daily
Daily crating is a generally good routine for this sort of dog and keeps him out of trouble in many ways. Even if you are home
with him, crate him for several hours every day.

Increase his exercise
This is a great deal of change for him. Exercise will help relieve stress and release excess energy. Be sure to play games
that promote cooperation and control -- skip tug-of-war, wrestling and chasing after him.

We do NOT Recommend:
Going to battle over a squeaky toy. Your dog, no matter how small, can injure you. When a dog shows he is ready to battle a
human, we already know that he is misinformed and confused. We need to straighten out that confusion prior to discussing that
unwanted aggression. If you attack him for threatening to attack you, you may well escalate his aggression. And, even if
you "win" he may decide to fight sooner and harder next time.

What he needs is education, not attack.

Anytime - ANYTIME - your dog threatens you -- hands on help from a qualified professional is the best next step. Aggression
is complicated and, if it isn't dealt with quickly, can get worse. In the end, it can lead to the death of your dog as surely as any disease.

Common Mistakes

• Thinking it is "okay" for him to have a chair or a toy that is "his."
• Assuming he won't bite.
• Avoiding the problem rather than dealing with it.
• Leaving toys that you know he is protective over out because "he likes them so much."
• Thinking this behavior will get better with time.
• Allowing denial of the problem to put other people at risk.

Further Advice
Seek any and all help, including from your veterinarian who might have some ideas about medication that could support an
ongoing behavior program.
