We just got a new puppy. He is a Lab X Border Collie and 7 weeks old. He slept in the kitchen last night and I do not want to wake up to that amount of poo and wee again tomorrow morning. It was disgusting as he has a really running stomach. We have another Lab who has a big kennel outside and the two of them are always in there together during the day so would it be ok for him to sleep outside at this age? It is going to go down to 6 degress tonight. ???
