Purebreed puppies usually have a predictable rate of growth, and most often fall within the weight and height range of the breed they represent. However, mixed-breed puppies don’t always follow any guidelines for growth? So, how do you know how big your puppy will get?
Most puppies follow the size of their mother, so if you saw the mother of your puppy, then you can know that your puppy will be within 10 pounds or so of her size. However, a rather large or very small father can skew this general assumption.
In general, your puppy should reach full size by around 6 to 8 months. At around 3 months, your puppy is a third to a half of how large it will be full grown. Large feet don’t always mean a large dog, but they are a good indicator. In short, watch your puppy’s growth carefully, and you can predict in a few ways how big they will ultimately be.
