What Am I Poem

In class at reading time, we have been working on inferencing. 

See if you can figure out my What am I poem!

I am the kaitiaki for people who are blind

For my job I only need you

I take care and am trusted

I am hairy all over

I have strong hearing muscles

I wear a harness for my job

I need to be exercised now and then

Very playful is what I am

Pronouncing around is what I do

When it’s not my duty to do a poo

I am very good at going round obstacles

If you look at me I am quite bondable

That's where my eyes come in

I am cute in all ways

And I live for about 4380 days

What am I?
