history: My dog doesn't seem to ever tell me when he needs to go outside! I walk him for about 30 minutes and he still uses the bathroom in the house.
current: I walk my dog for 30 minutes at a time but no matter what, he always ends up using the bathroom inside! I wish he would left me know if he needs to go out.
next: On no!  That is no good!  Is he still a puppy?
