Why is my puppy anyone snappy and aggressive to my mother?

My schnauzer-poodle mix is only about six months old, and sometimes, not adjectives the time, he lunges and snaps at my mother. He gets very vicious but he never bites enough to break the skin. It's not every time my mother is around me, or him, solitary sometimes. Why is he doing this and how do we train him to not do this ever?
shut him out every time he does it or a few mins then bring him vertebrae in , if he still does yelp loudly and put him back out side he will return with the message
Does your dog do this when you are holding him? If that is the case, he is protecting you and should be put down forthwith. Have your mom feed your dog really good treats that he only get from her (like real meat) and eventually he will learn that she is good and give yummy treats.

My mini dachshund is aggressive towards men and more so when I hold her. I am working the above method with her and her attitude has improved. Also, I don't hold her when men are present as she of late seems to feel the need to protect me from them.
I think your mother needs to be a bit more assertive with this pup. He seem to think she is a pushover. Is he right? Does she let him get absent with bad behaviour?
because he sees your mother as his peer, not as a boss. when the pup does this, your mother requests to grab him by the nose, give him a rap on the muzzle beside two fingers and say NO loud enough to startle him.

this will stop him from that behavior. if she never puts her foot down, it will simply get worse. no one else can do it. only your mother can, to show the pup that SHE is not gonna give somebody a lift it from him.
if someone else defends her, the pup will still walk adjectives over her.
Answers:    Your mom being assertive or threatening to this pup will make the problem worse. Do not take suggestion from people on aggression unless they are canine professionals. With a problem like this you need to refer to a trainer so that it doesn't become worse. The fact that he doesn't break the skin is a good sign. Dogs always bite for a function. What happened in all these situations main up to the bite? Severe punishment around mom may make the situation worse by causing a negative organization with mom. The best advice is to consult a trainer and not consult slapdash people. Your dog may be possessingg you or the area around him. Your mom may be approaching the dog in a channel he feels like she's threatening him. If that's the case trying to be "assertive" will lone make him increase his violence. That is because most people do not know how to show proper direction. They think being the alpha means staring the dog surrounded by the eyes or being "tough" with it. Leadership is calm but assertive. Leadership is not threatening. If you donate me more details I may be able to pin-point the problem for you. Otherwise, do not take anyone's advice. Even a dog trainer can not explain to you what to do without knowing more details so certainly don't take direction from people who are not professionals and also do not know the details of your particular situation.

In one of the cases I treated a dog was snapping at a guy's dad. It turns out that the dad other made the owner of the dog (his son) feel stressed, unhappy, and anger when he came over. The dad yell and insulted the dog to the son. Then he came up on the dog while he was laying surrounded by his bed and approached him from overhead trying to pet him. The dog snapped because the dad had a threatening energy and behavior, caused the owner to stress out which the dog can touch, and the dad approached the dog from overhead which is threatening to the dog.

We solved the problem by teaching dad how to approach the dog without threatening it. We also told the owner that if dad couldn't be nice when he be visiting, then just put the dog absent from all that negative energy.

Dog hasn't bitten since. The dad be causing the biting. Once they realized why the dog thought he had to protect himself, we solved the problem.

Another dog bit his owner when the owner put his mitt on the couch cushion the dog was sleeping on. The owner thought the dog bit unprovoked. The dog bit for a reason. The dog possessed furniture and thought he be in charge. So the dog was not allowed on the furniture, we devised a treatment plan to show the dog that the personality was the leader, and the dog stopped snapping.

So it all have to do with context. Consult a professional.
this be caused by roughhousing with the puppy when he was cute. Act resembling the mother dog would and disclipine the puppy or this will only get worse<
Your mom requirements to put a stop to this, NOW, while he is still a pup.
Make a penny shake can. Rinse out a pop can and fill it with 12 pennies and tape it shut. Have a few of them made and sitting around the house.
When he starts to do this, shake the can loudly, and hold her firmly say no.
Your dog does not understand that your mom is his boss and he needs to memorize this immediately.
Also, after using the shake can for a couple of days, have your mom start feeding him, not you.
Whoever "owns" the food bowl, is the ruler in the house. By her controlling his feedings, he'll start to get the message.
He is developing protective behavior around you. It isn't fully developed yet.

What I would do is if you are holding him and he does this to her I want you to put him on the floor and both of you turn your backs on him and don't salary attention to him until he calms down and stops. You have to do this IMMEDIATELY when he does it or else he won't obtain the picture that when he growls and lunges at your mom that the consequence is being ignored. You must do this EVERY time he does that. Eventually he will get the message. I would also do this whether he gets aggressive around other people as well.

Also, have your mom taking turns feeding him (or at least handing the food to him) will allow her to assert dominance over him. How this should be done is when you enjoy the bowl of food in your hand, have the dog sit while you put it on the floor. If he rushes the food, pick it up out of his manage again and tell him to sit and stay (continue to say stay as you put the food down) once the food is on the floor and he is staying you can tell him to "carry it" and allow him to eat. You should do this process anytime you feed him as well (anyone who feed a dog should do this, my parents and I do this whenever we feed their dog).

If you are allowing him free access to food, I would stop that at once and feed him the suggested over 2 or 3 feedings a day. If he isn't done consumption after 15 minutes, take the remaining food away. He will eventually learn to drink at meal times. Hope this helps.

EDIT:
If your dog does not know the sit and stay commands, work on guideline them to him.
