One of the main questions people ask when adopting a mixed-breed puppy is "What size will it grow up to be?" To help answer this question, we’ve developed a proprietary algorithm that uses the breeds identified on each chromosome in a mixed-breed dog to predict the likely size range a puppy will develop into when fully mature.
This prediction is designed to estimate the weight range at an ideal Body Condition Score (see below). Of course the actual mature weight of a dog can be influenced by many factors outside just genetics. Weight can also fluctuate over time due to variation in a dog’s health status, nutritional and exercise regimens.
Body Condition Score
A Body Condition Score is an essential mediator of the weight a dog will eventually reach. A dog’s score is a reflection of the amount of muscle build and fat deposition around its skeletal frame. Significant excess or deficiency of these core body tissues can cause two dogs of the same breed with similar size dimensions and build to differ significantly in weight. Additionally, nutritional variations during key developmental stages can have an impact on a dog’s ultimate body size and weight.
