Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
 Mbwa wangu alizaliwa nilipokuwa na miaka 15. Miaka miwili kutoka sasa, mbwa wangu atatimiza miaka 4. Nina umri gani sasa?


### Response:
 Miaka miwili kutoka sasa, mbwa wangu atakuwa na miaka 4, hivyo mbwa wangu ana miaka 4 - 2 = <<4-2=2>>2 sasa.
Hivyo, mimi nina miaka 15 + 2 = <<15+2=17>>17 sasa.
