A dog trained to detect changes in her young diabetic master's blood sugar levels is a lifesaver, the boy's mother has said.

Springer spaniel Jess retrieves a testing kit if she smells that six-year-old Jac, from Gwynedd, has blood sugar spikes or dips.

The four-year-old dog was self-trained by the family and is now an accredited medical detection dog.

Jac's mother, Emma Williams, said Jess was her son's "best friend".

Jess has been with the Williams family at their home near Porthmadog since she was a pup.

But when Jac was diagnosed with type 1 diabetes, his parents decided to have her trained to detect the glucose levels in his breath.

Jac's mother said: "She's just like a pet but she is always working. Her nose is always going, she alerts whenever she senses something going [on] with Jac.

"He'll tell you she is his best friend and she does save his life".
