Healthy weight?

Question
Hello.  I have a female fawnequin great dane.  I believe she is around two years old and we rescued her from a lady that was already breeding her and was allowing her to be attacked by other dogs on the property.  i don't remember how much she weighed when we got her about four months ago, but she was obviously malnourished - very skinny withribs showing badly, coat not healthy and lots of scratches and cuts from the other dogs.  all her cuts have now healed and her coat looks great.  she is happy and friendly instead of terrified like she was.  my question is this, i have been feeding her 7-8 cups of dry dog food a day, sometimes with a raw egg sometimes not.  i think she now weighs about 90 pounds.  what is a healthy weight for her at this age?  and at what age do they reach their maximum weight?  thanks for your time.

Answer
Maximum height is reached at about 14 months.

Healthy weight for a bitch of 29 inches at the shoulder is 46 kg or 100 lb.  Our show bitches weigh about 55 kg and up but they are above the minimum size.

By the way, there is no recognised colour of fawnequin, it's made up by people trying to get more for the puppies.  It is the result of breeding fawn to harlequin.
