Here is another post I wrote earlier that may help you and your dog to stop biting you... if it is merely normal puppy mouthing/play nipping.
Here's my earlier post:
Oh, I remember those days with my Puma pup!! We called it shark biting! Ouch!!!
So when Puma would start biting us, I would immediately redirect
with a safe toy that she could chomp down on.
No punishment at all, just redirect. After all, remember puppy mouthing is normal, they just need to be taught NOT to bite on human skin. If you didn't teach your dog earlier, it is ok, start now
I even kept a small plushie toy around my neck on a cord for instant redirection. Especially when I was socializing her around other people. I never wanted her to practice biting on others, even in fun.
If the toy redirection didn't work, I would get up and leave the room for a quick moment to show her that I wasn't interested in engaging in that type of behavior. I didn't say anything, just got up and left for a moment. Usually leaving the room for less than a minute is sufficient to teach the dog that hard play biting brings the play time to a halt.
I'm personally not a fan of sticking a dog in their crate for a quick "time out" for play biting like this, bc I always want my dogs to looooove their crate and never have any negative association with their crate.
Plus you can get bit moving the dog to the crate if the pup is still trying to play bite. I had better luck with just getting up and leaving room for a moment. Keep a baby gate close by and this will really help to quickly and safely separate yourself from the dog for a quick moment.
***I also would say "ouch" but not
in a shrieky high pitch. That excited tone can just heighten
some dogs-- and make them play harder. So for us it was a simple Ouch
, sort of a tone like you hurt my feelings. This will help teach your dog bite inhibition
, meaning if they do put their teeth on human skin it should be very gentle.
But---when the shark biting became too rambunctious at night, because she was overtired I would simply put her in her cozy crate gently with a safe chewy item like a bully stick. No punishment at all. Soon we would find her crashed out sleeping soundly. Soon we could just tell her in a fun happy voice, "Puma, go to your crate" and she would run there happily knowing she would get a great chewie in her crate.
And, yup, she would always get so much more shark bitey at night time. It is kinda like a toddler getting overtired.
When a dog is overtired they are most likely beyond the ability to learn and train, so I have found it is just best to send them gently to their crate or bed or relaxing place to sleep it off. Pups need A LOT of sleep!!!
