Frequently asked questions
- How does the puppy growth calculator predict adult size?
- It uses current age, weight, and sometimes breed size class to project adult weight with common growth curves. Mixed breeds are estimates only.
- Why did my vet's prediction differ?
- Growth spurts, nutrition, and genetics all shift the curve. Revisit the projection every few months with an updated weight.
- Should I use this to pick a crate or collar?
- Use projected adult size for long-term gear, but buy puppy sizes that fit now with room to adjust. Collars and harnesses must fit today, not in six months.
- When is slow or fast growth a vet concern?
- If your puppy looks much smaller or heavier than littermates, or ribs are too prominent or hidden, schedule a vet check. Growth issues can be nutritional or medical.
