Hiya, I got my pup yesterday morning, when I got to the ladies house the puppies were outside in a large pen, they all looked pretty happy and had a kennel to sleep in, so when I got him home I knew that outside is where he should go to the toilet, but I didn't think that outside at my house was the place to go.

I took him utside probably every half an hour the first few times he didn't go, but then he started going and also crying to go outside, as well as in the middle of the night he wouldn't settle so I let him out and he went.
Is it normal for such young pups to be toilet trained, wether they were raised indoors or outdoors?
