Miss Orange and Purple are both still growing steadily but the same cannot be said for Mr Maroon who is not growing steadily, he is out of control! Nothing like a Big Brother to take care of you right? This is not to say that he will be an unusually large dog though, Raimi, his dad, was not only not the biggest puppy in the litter even at 8 weeks, he was outweighed by at least one of his sisters. During puppyhood it's not easy to tell who will mature the largest because at this time their body is not telling them genetically how big to be, it's telling them what to do to survive. The bulk of their growing occurs between 7 weeks and 6 months and that is when their genetics will start to take over. And don't be fooled, Orange and Purple are not runts, they are just smaller than Maroon - in fact, true runts are not as common as you might think, usually the puppy considered the 'runt' is just smaller than the rest of the litter but there is no reason to think it will not be a normal sized adult. Another myth dispelled.
