Anyone got any recommendations for a good quick growing toughish grass seed mix to use in patches dug up by our loveable but digging loving black Labrador? It is mown using a very old sit on mower but isn't exactly a perfect example of a lawn, being originally part of a field and now home to ducks and chickens who don't actually cause a problem -on that area at least! I'll obv have to section the areas off somehow once I've sown it but they are quite smallish areas. A lot of grass seed I've seen seems too tender for where we need it and for where we live. It's high up, windy and wet!
