House training

[kyto27]

HI! I am new to this forum and stumbled upon it by accident looking for help with my 8 month old Basenji named Rosco. We adopted him from the local rescue league when he was 6 months old. We had no idea what we were getting into haha! The problem that i am having is one the boundless energy woohoo he can just go and go!! The biggest problem is at first we thought he might be house broken with just a few accidents but the first snow came and he was not happy about it and since then (about a month ago) he has started to pee and poo in the house. Not all the time and never in his crate. How do we teach him not to go in the house and go outside only? We are new to this our last rescue was already house trained. We do also have the problem he likes to chew and take things and run around the house. We realize this is puppy behavior, he sure does keep us busy. We always say how can something so cute be so bad!
