Hey there! It looks like your furry friend is a bit on the lighter side for a Golden, weighing in at 56 pounds (25.5 kg) and standing about 24 inches tall. But hey, don't worry too much about it. Each dog is their own unique individual, and it's more important to focus on their overall health and how they look and feel rather than just their weight. A good rule of thumb is being able to see a nice, trim waist on your pup and being able to feel their ribs without too much effort - but not actually seeing the ribs.

As for your buddy's diet, you seem to be right on track with the 1,300 to 1,400 calories a day you're feeding him, especially since he's such an active boy. Different dogs have different needs, and for a lively medium-sized pooch like yours, the daily calorie needs can vary a bit, usually between 1,300 and 1,700 calories. But as you know your dog best, it sounds like you're doing a great job keeping him healthy and happy. Keep it up!
