I'm looking to buy a beddy/whippet pup and wondered if anyone had any advice about coat colours, are they born black/brown and lighten or if its born with black coat likely to stay black. also if rough coated would you know coat type at birth or do they develop this later. I really love the ones that are rough coated that end up blue/grey. but I have no idea what this would look like as a puppy thanks for any help or advice
