# Dog to Human Age Calculator

Convert a dog's chronological age into human-equivalent years using size-adjusted multipliers. Also returns life stage (puppy, adult, mature, senior).

## When to Use This Skill
- User wants to know how old their dog is in human years
- Questions about "is my dog senior yet?"
- Pet age comparisons or life stage advice
- Birthday or adoption date calculations for dogs

## Fallback Calculation (if API unavailable)

Use this table for manual calculation:

| Size   | Year 1 | Year 2 | Each year after |
|--------|--------|--------|-----------------|
| small  | 12     | 9      | 4               |
| medium | 13     | 9.5    | 4.5             |
| large  | 14     | 10     | 5.5             |
| giant  | 15     | 10     | 6               |

**Life Stages**
- **puppy**: < 1 year
- **adult**: small/medium < 7, large < 6, giant < 5
- **mature**: small/medium 7–10, large 6–9, giant 5–8
- **senior**: above mature threshold
