> i know it might sound mad but i really do want to bond with her and be a mum like figure to her.
If by 'mum like figure' you mean somebody your dog can trust, feel safe with and look to for direction there is nothing wrong with using the term 'mum', as long as you remeber you are 'mum' to a dog and not a human

Bonding can be achieved with reward based training along with respecting the dogs needs and the basics to how the dog thinks ie. they only understand the words you teach them, they aren't 'naughty' to get back at you, they don't 'know' that pooping on your very expensive rug is wrong, the expensive wooden furntiure is just as much fun to chew as a dog toy so they know no difference - it's up to you to teach what is allowed etc....
A good training class should help with training and through training - bonding. I've found I have the best bond, out of my family, with my dog, as I have done all the training, grooming, feeding etc. he trusts me above anybody else and will look to me for direction.
I personally do not allow my dog on my bed for several reasons - #1 upstairs is a 'dog free' zone so the cat always has an escape if she feels she needs it, #2 due to his breed, stairs were a no-no as a puppy so he has learnt not to go up them. #3 he will not
fit in my bed with me & OH in it!!
I've found grooming to be a great bonding time. It's a very good idea to get pup used to being groomed & having her feet/ears/mouth inspected from an early age. This is something you can start straight away, but as with any training session keep it short, don't force pup to put up with things they don't like, take things slow, end the session on a 'high' (it's better for pup to remeber the session finishing in a happy/relaxed state of mind), reward any progress.
