Smaller breeds have a faster metabolism, which means they burn energy at a much higher rate. Depending on their body condition and activity levels some may need twice as many calories every day as larger breeds
Generally speaking, puppies need more food than adult dogs to support their overall health & development during the early months of their lives
Larger breeds may have slower metabolisms, but they definitely have larger appetites! Be careful not to give in to those 'puppy' eyes too often as you could be unknowingly over-feeding your canine companion
If your dog is particularly active or is a working dog, you may want to consider feeding a little more than recommended to make sure they have enough energy to keep up
If your four-legged friend is expecting a litter of puppies you may want to feed a little more to ensure that she, along with her pups are getting all the nutrients they need
Less active dogs don't burn as many calories, so you may want to consider feeding a little less than recommended to avoid any unwanted weight gain.
Once your dog is settled on to a food, keep an eye on his weight as this is the easiest way of telling whether or not the feeding amounts are correct. Compare your dog's body shape to the dogs pictured below. Your dog is at his ideal weight when you can feel, but not easily see, the last two or three ribs and when there is an easily identifiable waist line when looking down from above.
