#3 – Cocker Spaniel
The most common cause of death for these wonderful little dogs is cancer, affecting up to 23% of the breed according to a 2004 study.
#4 – Doberman Pinscher
Not only do Dobes fall in the top 10, they are actually found to be one of the top 5 breeds most likely to have cancer. While they are prone to many types, mammary cancer has been found to be a leading cause of death in female Dobermans.
