A dog named Daisy played an important role in saving her owner's life by detecting a fatal disease.

XQ reports with reference to Lent.az that in 2008 dog owner Claire Guest went for a walk with her three dogs. Suddenly, Daisy refused to get out of the car and began to communicate with her owner in an unusual way, showing her chest area. This unusual event led to the discovery of a tumor in the woman. Later, doctors diagnosed her with breast cancer.

Thanks to the early detection of the disease, 45-year-old Claire was able to save her life by undergoing a successful course of treatment.

Inspired by this experience, he and Dr. John Church founded Medical Detection Dogs (MDD), a charity dedicated to training dogs to detect various diseases in humans.

The organization quickly expanded its activities, proving that dogs can detect not only breast cancer, but also other diseases. The training program includes identifying hypoglycemic episodes in patients with type 1 diabetes.

Today, more than 80 people in the UK have MDD-trained assistance dogs, significantly improving the quality of life of people with a variety of conditions.

An important part of MDD's research efforts was the discovery of dogs' ability to detect illnesses by smell long before symptoms appear.

MDD founder Claire Guest thanked her rescue dog Daisy, who died in 2018, and emphasized the importance of dogs' role in disease prevention and detection. This historic event was the starting point for the development of new diagnostic and treatment methods, opening perspectives for fighting diseases in their initial stages.
