We compared serum concentrations of zinc, chromium, and iron in dogs with cancer to those of normal dogs. Dogs with lymphoma (n = 50) and osteosarcoma (n = 52) were evaluated. Dogs with lymphoma had significantly lower ( P = .0028) mean serum zinc concentrations (mean ± SD; 1.0 ± 0.3 mg/L) when compared to normal dogs (1.2 ± 0.4 mg/L). Dogs with osteosarcoma also had lower mean serum zinc concentrations (1.1 ± 0.4 mg/L), but this difference was not significant ( P = .075). Serum chromium concentrations were significantly lower in dogs with lymphoma (2.6 ± 2.6 μg/L, P = .0007) and osteosarcoma (2.4 ± 3.1 μg/L, P = .0001) compared to normal dogs (4.7 ± 2.8 μg/L). Serum iron concentrations and total iron‐binding capacity were significantly lower in dogs with lymphoma (110.8 ± 56.7 μg/dL, P < .0001, and 236.6 ± 45.6 μg/dL, P < .0001, respectively) and osteosarcoma (99.6 ± 49.3 μg/dL, P < .0001, and 245.0 ± 43.8 μg/dL, P = .0011, respectively) when compared to normal dogs (175.1 ± 56.7 μg/dL and 277.1 ± 47.4 μg/dL). Mean ferritin concentration was significantly higher in dogs with lymphoma (1291.7 ± 63.0 μg/L) than in normal dogs (805.8 ± 291.1 μg/L, P < .0001) and dogs with osteosarcoma (826.5 ± 309.2 μg/L, P < .0001). Further investigation is needed to explore the clinical significance of these mineral abnormalities in dogs with cancer.
