Probably a stupid question, but i went to see a friend yesterday who has a beautiful chocolate lab puppy. It got me thinking - when I was a child (I'm quite ancient) I only remember yellow and black labs. Now I would say chocolate is probably the most popular colour for a lab round here, but I think I only cam accross the first one about 20 years ago. Are they a new strain, or did I just lead a very sheltered life prior to this? Also the lovely "red" ones seem new too.Are they a distinct type, or just a very dark yellow one / very light brown one?
