Fig 3. Percent of golden retriever dogs dying of cancer and age of death over time.

(A) Scatter plot with fitted regression line and 95% CI showing percent of golden retriever dogs undergoing necropsy exam that died from cancer by year. The results show a significant (P = 0.38, R² = 0.16) but weak increase in the proportion of dogs with a cancer diagnosis over time. (B) Scatter plot with fitted regression line and 95% CI showing age of golden retriever dogs presenting for necropsy over time. The results show a significant but week increase in age over time (P = 0.01, R2 = 0.009).
