These next steps will be much more effective once you have established yourself as leader as explained in step #1.
A huge part of this training is to have items that will refocus a puppy's attention.
While treats can do this, it is extremely temporary. Instead, you'll want to have something that not only grabs your Shih Tzu's attention but also keeps him focused on it.
The best way to accomplish this is to have certain toys that are 1) super interesting 2) meet a pup's needs if he is teething and 3) are only reserved to distract after an attempted nip.
If you try to do this with toys that your dog already has, it will limit success. You'll also want very engaging toys for this to do the trick. Those that speak or make funny noises, or those that satisfy a teething puppy's strong urge to chew
are great choices.
Ahead, we will show some great recommendations for this.
There are 2 parts to this.
The 1st is if you can pull your hand away before the nip occurs. The 2nd is if you could not pull away fast enough.
1) If you've avoided the nip:
Withdraw away to make distance between you and your Shih Tzu.
Offer one of the toys that is reserved for this situation.
When your Shih Tzu mouths the toy, give praise and allow your puppy or dog to enjoy it. This will teach a puppy or dog that there are much better options for to focus his biting urges on.
As time goes by, if you see that certain toys keep your puppy busy and would be valuable additions to his toy collection
, move them there and keep a new one for times with attempted nips.
Expect a teething puppy to be pleased with a good teething toy to the point that his chewing urges are directed there, and not to you.
2) If the nips occurs:
Loudly and firmly say 'No!'. This will be equivalent to the 'yip' that your puppy heard from a littermate that was bitten to roughly.
Ignore your Shih Tzu for 3 full minutes. This MUST be a full and complete ignoring of the pup. This means no eye contact and no speaking. If needed, rise from a sitting position, to gain physical authority and prevent further nipping.
This is because the goal is to have the pup worried that you, the Alpha, are considering banishing him from the pack due to the offense.
After the 3 minutes, speak to your puppy normally and continue on with the interaction you had previous to the nip.
If the pup nips again, repeat your reaction again. This can be done 3 times before needing to increase the 'banishment'.
If 3 nips have occurred and your Shih Tzu is still out-of-control or if he keeps coming at you without allowing you to take pause, you will want to give a time-out.
