Hi this is our first time posting, but my Husband and I are in search of some help with our Corgi puppy. Charlemagne is almost four months old and is a pembroke welsh corgi. He is super wonderful and his training is going great for the most part, but there is one thing that we are having trouble with and that is his aggressive biting. If he is eating or chewing on something he is not suppose to and we go to take it away he well try to eat it has fast as he can and has bitten us pretty hard a couple of times. If anyone has any ways to train him against this behavior and what we can do we would greatly appreciate it.
A puppy this young is just treating you as he would another pup. "It's mine!! " He needs to learn that you are not another puppy in fact no humans are...you are the leaders. Any kind of training will help but a good resource is googling Nothing In Life Is Free to determine the things we humans do to foster our dog's belief that we are their followers. At this point I would always trade something, treat or toy for the item you want. If any teeth touch your skin or a growl sounds,say No and give a time out for a few minutes in a puppy safe place. Also, work on the leave it command. I have always taught it by saying "Leave it" and trading a treat for an item, then occasionally immediately giving the item back. You can practice this randomly and be sure to give the item back if he releases it when you say leave it. I think this method helps them learn that you are in charge and not a danger to them.
Kaylee was a bit of a biter when she was younger. We tried to desensitize her to use holding and taking away her toys/chews by playing "Let Me See" after advice from our trainer. You hold the toy and say the command. You let go. Eventually you take it away and give it back. That way the pup no longer thinks it's a big deal for you to hold or take away "their" things.
For normal biting your hands, we did two things. One, I hand fed Kaylee a good bit, like one meal a day. It helps with bite inhibition and food possession behaviors. Second, my husband and I would take turns playing with her and the one not playing would have a shake can out of sight. If she bit me, I'd indicate to him to shake the can. It worked pretty well and has she stopped play biting. If alone, I would yelp, stop all play and stand up, if she bit me. This way she got cues she could understand that I did not like being bitten and something she wanted (tug of ware or ball) would stop if her teeth touched me. You can also include teeth touching you clothing with this.
I suggest a bite inhibitor like Bitter Apple for things that she really shouldn't chew (wires, furniture, etc.). Most dogs don't like the taste.
Excellent suggestions. One other thing I would caution. Be sure you are not playing rough with him at all. I've found that, especially guys, like to rough house with a puppy. And that can bring on aggressive, biting behavior. With mine, I work on exchanging items. If I constantly take things away, the dog learns they must guard their stuff. However, if I teach "leave it" or "give it" or "drop it" I can get the pup to exchange one thing for another and they don't resource guard as much.
For biting like that, I never pull my hand away. I grab the scruff and I pin them down, say "No bite!" sharply and hold them until they stop squirming/resisting. Both my dogs learned early on that I am not afraid of being bit. Now they don't even bother so much as growling at me, and if I have to pin them, they go belly up.
Work on the aggression itself. Get your pup use to you giving and taking things away. Do not act timid or nervous. And if you're given aggressive behavior do not get upset or mad, just correct it.
Even now, I'll random go up and take toys, treats etc... away from my dogs. They don't make a scene about it, I praise them and give it back.
Hope this is of some help. Best of luck!
