A teenager with epilepsy burst into tears of happiness after her family surprised her with her own therapy dog.
Summer Shott, from Raynes Park, south west , was told the fantastic news in an 'anonymous' note.
The note, which was actually from her mother Cherie Johnson, detailed some of the problems she was having at school before asking her to open a secret flap.
Inside, it revealed Summer was getting a new best buddy - at which point she exclaimed 'you’ve given me a dog?' and started sobbing.
Summer Shott, from Raynes Park, south west London, burst into tears after her mother surprised her with her own therapy dog. The teenager has anxiety and Cherie Johnson decided to buy the dog as a surprise for her 16th birthday

The pure shock and delight on Summer's face was luckily caught on camera by her mother.
A later clip shows Summer crying even more as she is presented with a chihuahua puppy called Buddy.
Ms Johnson said: 'I knew Summer would be ecstatic but her reaction was absolutely magical.
'I'm so proud of her instant reaction to protect him, she thought her crying would scare him and that was the biggest concern for her, not being in his face and getting excited.
'It was all about making him feel safe. I'm allergic to anything with hair so she has always been under the impression it was never going to happen, which is why we have a tortoise named Eddie.
'Her 16th birthday was coming up so I caved and decided that I would arrange for her to have a dog that could help her.'
Summer was born with cerebral palsy and as a result has hemiplegia which physically affects her right side, but she also has epilepsy.
Children with hemiplegia really struggle with confidence and anxiety, so she can't do the same things as girls her age without a chaperone, including going to the park or shopping with her friends.

Ms Johnson revealed the surprise in a sweet 'anonymous' note that detailed some of Summer's problems
Summer had recently been in hospital after having a long episode of seizures and Cherie was told by a few different medical professionals a dog could help reduce her anxiety.
Ms Johnson added: 'The seizures she had this time were triggered by anxiety. Summer had just finished mock exams and has been under a lot of pressure at school doing extra revision lessons.
'She's always felt she doesn't fit it and has to listen to the girls at school talking about what they're getting up to at the weekend and it knocks her self-esteem.
'Summer has also been bullied before because kids look at her and don't understand her disabilities as they are "hidden".
'Having a support dog means she comes home every day to her own little friend.
'Since having him she looks forward to the weekend, she's got someone to look after rather than her always being looked after and it's given her so much confidence.
'Her anxiety levels have dropped dramatically and she hasn't had any of the bigger seizures since she came out of hospital.'
