How big can a 3-month-old mastiff puppy actually get and is it normal for them to be this heavy already?

I’ve noticed that our 3-month-old mastiff is already quite large, and he seems heavier than I expected for a puppy his age. It surprised me during our vet visit yesterday to learn how much he weighed when they put him on the scale. I know mastiffs are big dogs, but is it normal for them to grow so quickly at this age? Should I be monitoring his diet or weight more closely?

Answer

It’s common for mastiffs to grow rapidly during their early months, which can sometimes be surprising for new owners.

  • Normal for mastiffs to have rapid early growth
  • Weight should be monitored regularly
  • Ensure a balanced diet appropriate for large breed puppies

Mastiffs are known for their considerable size, and it is typical for them to grow quite quickly as puppies. At just 3 months old, they are in a fast-growth phase, which can often be surprising, even for experienced dog owners. It's important to ensure that your puppy is receiving a balanced diet specifically formulated for large breed puppies, as this will support healthy growth and prevent issues related to overnutrition or obesity. Regular weight checks with your veterinarian can help to ensure your puppy is on track and growing appropriately.
