Question
i have a 2 and a half yr old great dane marley she is 3/4 silver black spots some white and some solid black beautiful dos she was a bout 85 pounds when we got her 4-5 months ago now she is healthy and is 180 pounds does she possiby have mastiff or another big dog breed in her she stands 6-2 6-3 on he hind feetdo you think she is done growing

Answer
That's how big great danes get!!! The color you are describing is called Blue Merle. 180 lbs is about normal,it's possible she is going to gain a little more weight or get a little taller but for the most part she is done growing. They grow upward their first year and hten start to fill out more the year or two after that. It's very common for a great dane to stand over 6 ft tall on their back feet and be pushing 200 lbs.Sounds like she was extremely unhealthy when you got her if she was only 80 lbs.
