**Why is my dog drinking his pee when he urinates inside?**



The inside of your home is the den and pack animals naturally like to keep their dens clean. They will want to relieve themselves as far away as possible from where they eat and sleep.

Given he doesn't do this when he is outside, I wouldn't regard it as a problem, per se, he is doing what comes naturally and cleaning up.
  
- Can you install a dog door?  
- If he is having trouble holding on, does he have a health problem?  
- He needs to be taken out more frequently

>During nursing the mother will clean the pups and stimulates them to urinate and defecate by licking the genital region. She swallows all of their excretions, keeping the birthing area clean and odor-free.  

In wolf packs the entire pack protects the mother and the den and help to raise the puppies.
