We are picking up our 8 week old shih tzu pup this week (he is a rescue pup and NOT a Christmas gift). We have been waiting for him since end of October. My question is on housetraining. The foster carer has never had the pups outside yet and they have a pen with puppy pads at one end and sleep at the other. I have recreated the set up for our pup but obviously would like him to eventually toilet outside. The problem is how cold it is at the moment. Should I wait a while until he gets a bit bigger (I know that would make it harder) or shall I start putting him out in the garden straight away? He is so small and it is so cold especially at night!
