When puppies bite your legs, you feel their sharp, needle-like teeth and your instinctive reaction is to move away. "More entertainment!" thinks the puppy, as he latches on more in hopes of being dragged for the ride. Jokes aside, the puppy nipping stage may feel like a nightmare to dog owners who are in desperate need of solutions to curb the puppy's relentless biting.
Puppies poop in the house often because they aren't yet fully potty trained. Just like babies, it takes some time for them to attain sufficient bladder and bowel control to be considered fully potty trained. On top of this, there are several other potential reasons why puppies poop in the house, so you may need to put your investigative hat on and consider several potential differentials, possibly with the help of your veterinarian.
