Looking for a second auntie (experience with big dogs)

Hi, 

We are a Chinese / British family with 1 four month old baby boy and one 1.5 year old dog (27kg). 
We're looking for a second nanny / auntie to support our current auntie who lives in. Main duties are looking after /walking our big golden retriever, house keeping and going to the market. 

We live near Happy Valley. 

Flexible on start date - we're not in any rush. 

Thanks.
