Thank you for all your answers. How big of a crate do you recommend? We've got this sort of transporter/crate which we brought her in from the breeders but I think she connects it with the car journey now... And it seems really small to feel comfortable in - she could just stretch in it, I guess.
Have fun at puppy class! I take it you're in the Netherlands? My aunt and uncle (and cousin) lived in the Hague for years, my aunt and uncle are back in Toronto now, my cousin has just started teaching and I know she'd love to go back. It's a beautiful place.
Thank you Nebuchadnezzar - yes, Netherlands is beautiful - we love it so far :-)
Really greatful for all your answers.
