Animal-loving actress Jennifer Aniston is bracing herself for the emotional loss of her beloved dog, after reportedly discovering her pet is suffering severe health problems.

The star has kept a watchful eye on her 14-year-old Corgi-Terrier, Norman, who defied death in January after wandering from her California home and narrowly escaping a car collision unharmed.

According to magazine OK!, the pooch is now suffering unrelated digestive problems, and Aniston worries his life is at serious risk.

A source says, “Norman is old and hasn’t been doing well. She’s terrified her best friend could soon be gone.”

The actress also has a three-year-old white German shepherd, Dolly, and was candid about her bond with her family of pets after Norman’s scare earlier this year.

She said: “You have to say goodbye way too soon. It’s just so sad. It makes me so sad. But their love is unconditional and I love that.”
