What Are the Factors That Affect a Pitbull’s Growth?

If you are concerned about your pitbull’s growth or feel like your dog is smaller in size compared to other dogs of the same age, then you need to understand that the growth rate normally depends on several factors.

The main factor that affects a pitbull’s growth rate is simply the dog’s genetics. There are different types of pitbulls and their size can vary according to their gender and also their age.

Another factor that affects the growth rate is your dog’s diet. The quality and amount of calories your dog is consuming have a big effect on how big your dog will turn out to be. If your dog is not getting enough calories, then it might end up growing more slowly than the other dogs of their age.

So, you need to make sure you’re providing your dog with balanced nutrient-filled meals regularly, especially at the early stages of its life, to ensure it will grow at a healthy rate and reach a normal size.

The average active pitbull needs to consume about 922 to 1,740 calories in a day. You can adjust the amount of calories according to your dog’s age and activity level. You can also consult with a nutritionist about the kinds of food that are best for your dog’s diet.

It’s highly recommended to take your dog to the vet for routine check-ups to make sure that it’s perfectly healthy.
