so, you should avoid punishing for toilet behavior in the house. it sounds like she really just doesn’t know the rules yet.
these two links are pretty similar and i’d read both. they should help.

remember, be consistent. good luck. housebreaking is the biggest pain in the butt regardless of the age of the dog.
Thank you for getting back to me. I have only had her around a month and she came from the RSPCA – she has been spayed and wormed and is up to date with all health needs / injections. I haven’t noticed any other issues in her litter tray. I did take her on an outing to my parents house and let her wander (I want to get her used to moving around in case I go away and need others to look after her) She does drink alot of water and urinates a lot – but this hasn’t changed since I got her. a bowlful every two days, she eats well – mainly dry food with a treat of wet food maybe once a week.
