Frequently asked questions
- How does the pet growth calculator work?
- It compares your pet’s age with a general growth curve and divides current weight by the estimated percent of adult size.
- Is this exact for every breed?
- No. Breed, sex, nutrition and health can change growth. Use it as a planning range and confirm concerns with your vet.
- Why does dog size matter?
- Small dogs usually mature earlier, while giant breeds keep growing longer. The size setting chooses a different growth curve.
