Hi again? clearly this is my first corgi and I have a bundle of questions, hope you all don't mind. We crate trained Boris from day one and he has been great, not a peep all night. We have had him for 3 month and suddenly the last week or so he settles in and then around 12 he barks all night we let him out to go potty he continues to bark. Could it be he is in pain with teething how should i correct this behavior. thanks for the help in advance 

I have a question for all the corgi owners out there. Boris is about 41/2 months old, we took him to a 6 week puppy training and try to work with him for about 5 min a day on everything. We were told that the nipping and mouthing was a phase due to his teething and he has improved his day one but he still lunges at your face playfully or mouths your fingers or arm. What should i do to totally stop this behavior even when playing. We have tried the water bottle as well.
