Have Sally for 2 weeks now and is such a good puppy starting to go on walks, loves company but knows when its bed time. the only prob i have with her is house trainning she goes when and where she fills like even on her bed. Was reading a little about crate training. is it a good idea, i thought this was more of an Americian thing but i see them been sold in pet shops and argos. Any info about this would be great.
