I'm so fed up right now, I need advice.
 

So I've had Richie since he was 6 weeks old, I know I should've known better but I didn't at that point and his old owner didn't really care about him so I took him in. He's now 14 weeks old and he's driving me crazy. I've trained him how to sit so that was pretty good. I've tried and tried to train him to stop biting but it's only have gotten worse. He tries to bite my hands, arm, shoes, feet, and pants, literally everything. I know he's a puppy and this is what I have to deal with but I just want it controlled. This summer we're going to visit my family. And I have cousins who are less then 10 and a nephew who is 3. I plan to get my dog to not bite at all during summer but it seems impossible as I've tried and nothing works. My dog loves strangers. He doesn't bite them in fact he gets so excited and goes crazy for them. But I'm scared that once he's comfortable he'll bite. So what can I do at this point? I don't know how much classes are and I'm guessing they're over $100 which my parents think is pointless as I could do it myself. He also barks at my shoes when I try to pull them away and thinks I'm playing. I leave him for 10 seconds and Coke back to him and he does the same thing. I repeat the same process and he proceeds. I just don't know what to do. I'm desperate and stressed.

He is probably too young for obedience classes yet and what he is dpong is not unusual. When they stay with their moms dog longer that behavior is usually taken care of, but he was young and needed you so got to go from there.

When he nips at you tell him no, don't yell, and puLloyd your hand away. Offer him a chew type toy instead. He will start to get the message, but again he is young.

Be careful with the young children. Very often young children and young pups don't do well together and yours is at the biting/chewing stage, and with some pups this can go on got awhile.

Until your pup matures, the best course is to keep him away from younger chidren who may be upset or hurt by his biting. Make, and stick to, a plan that allows the other kids to maybe pet your pup for only a brief moment while you are holding him.

Other than that, stick with the advice you have been given for the long term breaking of biting habits. Pups bite until BOTH maturity and training kick in.

I agree with keeping him separated from the small children when you visit. Do not risk a bite.

Training is often a long-term, repetitive, frustrating process. Use a combination of yelping, withdrawing hands and other biting targets, using "No bite" command, and withdrawing attention.

When Max was a pup, he thought it was great fun to nip at my toes first thing in the morning. I said "no bite" and put him back in his xpen while I brushed my teeth and dressed. He learned that if he wanted his freedom, he couldn't bite.

When we played, if he bit me, I crossed my arms across my chest and yelped. If he continued, I got up and left the room. He wasn't able to follow because of the baby gates.

Make sure he has plenty of appropriate, safe things to chew on. The teething process is likely complicating your training. Max learned bite inhibition and would gently chew on my dad's fingers during the teething process.

I know this is frustrating. Trust me, one of mine did this as a puppy and at the time it felt like he would never stop. But he did. Puppies play bite and with time they learn to mouth rather than bite when they play. Mine hardly even mouths anymore.

:thumbup::thumbup::thumbup: Great advice, as always!

Spot on advice! Please restrict any interactions between the kids and your puppy! Even without the biting issue, Yorkies aren't good with children - the random and quick actions of toddlers and young kids really scare Yorkies.

Be consistent with your training. And spoil your puppy with a variety of chew toys. Get like 10 different ones and rotate them. Make sure you always supervise when he's playing with the chew toys and throw them out once there are signs of the toy being chewed up.

I thought I'd add, as important as it is to train/ teach the pup how to behave (not biting), it is just as important to make sure the kids understand how to play with the dog as well. Ie. Do not get crazy around them, do not put their face in front of a the puppies face, do not grab at them.

Puppies bite/ nibble, this is part of their nature. You must teach them the appropriate way to interact with you.
You can do this with numerous ways, as others have suggested. Sometimes a simple firm correction is enough (ie. "NO!"). Or you could correct and redirect (ie. AhAH! and then give the pup a toy instead). Yelping is another thing you could try, as this is what they do in nature to let another puppy know it is biting to hard. Another option is to simple stop playing and completely ignore them until they calm down.
