Thanks for the welcome. My Danes are Zeus (brindle, age 5), Poppy (brindle, age 5) Buster (Harli mis mark, aged 2) and Kiera (fawn, age 11 months). My Labrador is Izzy and she's 10 months old, yellow in colour.
I am about to become the proud owner of a mantle bitch, she is now 6 weeks old, so waiting until she's old enough to leave her mum and litter mates. Although the UK Kennel Club have not announced anything yet, they are in the proccess of adding the Mantle Dane to the breed standard. I am lucky that my little girl is beautifully marked with the full white collar.
Will try and put some pictures of my dogs on when I work out how to do it.
