conv: 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. I walk my dog for 30 minutes at a time but no matter what_comma_ he always ends up using the bathroom inside! I wish he would left me know if he needs to go out. On no!  That is no good!  Is he still a puppy? No! He's about 2 years old now. Sometimes I think he does it out a spite when he's not getting enough attention! Hopefully he is not doing it out of spite!  Maybe you should hire a dog trainer to see if they can correct his behavior. That's not a bad idea!
