For Griffin the golden retriever loading the washing machine and flushing the toilet are all in a day's work.
The dog is an invaluable companion for Clare Syversten, of Northolt in north west London, who suffers from a degenerative bone condition which can leave her with dislocated joints from the slightest movement.
In the last two years the assistance dog has learned how he can help the 26-year-old, including getting her dressed, loading the washing machine - and even flushing the toilet.
Griffin can also help Ms Syversten change the television channels in her home.
While out and about, Griffin presses the buttons at road crossings, put's Ms Syversten's fruit and vegetables into separate bags.
He also grabs items on low shelves that she can't reach and hands her purse over the the cashier when paying for shopping.
And his work is not done when they return home, as Griffin has been trained to open and close doors for his owner. He can also help her to transfer from her electric wheelchair to a manual one.
He also helps Ms Syverston undress before bedtime and is on hand to grab the telephone for her when she cannot reach it.
Ms Syversten, a volunteer charity worker, said: 'Having Griffin around has given me my confidence back. I really couldn't live without him.
'My condition seriously limits what I can do and I used to depend a lot on other people; even something as trivial as picking up a pen would cause my wrist to dislocate.
'I don't need to depend on other people now as Griffin just does everything for me; he's my hero. I think it would be easier to list the things he doesn't do.'

Ms Syversten has Ehlers Danlos Syndrome.
The syndrome is a degenerative condition which means even when Ms Syversten makes the slightest of movements, her joints can dislocate leaving her struggling and in pain.
She met Griffin through the charity Canine Partners, who match assistance dogs with disabled owners to make their lives easier.
She attended a training day in July 2013 and said as soon as she saw Griffin she knew he was the dog for her.
'It was definitely love at first sight, I knew as soon as I saw him that he was mine,' she added.
'The first thing I thought was "wow look how big your paws are!" and before long he jumped up on my lap, he was so friendly.'
Griffin has been helping Ms Syversten for nearly two years and his skills attract a big audience, particularly at the supermarket.
She said the dog has made her feel more assured about leaving the house.
'I used to be really quite nervous about going out on my own but that has all changed now. Now though, I have no hesitation about going out and it's all down to Griffin.

'I really do not know what I'd do without him; he's changed my life completely.'
Jenny Moir from Canine Partners said: 'The difference Griffin is making to Clare's daily life is amazing but typical of the hundreds of canine partners working with their disabled partners.
'Not only are the physical tasks beneficial, which gives the disabled person some independence back, but also the dogs increase self-esteem, confidence and companionship.'
