My 12 week old maltipoo puppy sometimes gets so hyper (especially at night) and will lead to inappropriate behaviors such as biting me/my clothes, jumping, and he will dig on the couch? I've googled tips on what to do with a biting puppy because I do not want him to be aggressive or act on dominant behavior. I've read to distract him with a toy, yelp in pain and go limp, or walk away and it doesn't seem to be working when he gets in the zone. I play with him plenty and take him on many walks. He does eventually wear himself out and crashes, but is there anything else I can do to teach him that biting and acting this way is wrong?
Also, is digging on the couch a normal behavior? To be more specific, he will dig and shove his face in the crevice of the cushions during his puppy crazies. How do I stop this behavior?
