i had a shletie when i was younger they are very nosisy and bark about everything so get earplugs. but the way we trained mine was making it a habbit to go out after he ate and then once in between and then he just started crying to go out and we would applaud him. they are great very loyal and hate being alone. my aunt still has one. they can also be very protective and dont know there size. but mine didnt like lilttle children so if you have kids be careful. other than that applaud him when it goes outside and rub his nose in it when he does it inside than spank him. tying him out side also works. we have a huge deeck so ussalyy mine would just go and chill outside. remember dogs dont really thin they learn on doing it over and over. so get him use to doing what you want him to do and theyll do it
