Hair can be easily collected, stored and have several characteristics suggesting that it may be useful biopsy materials. The mineral contents of the primary hair give an overview of the mineral levels in the body’s tissues and the changes that occur over time. In the present study correlation coeffi cients of three micro minerals viz. (Copper (Cu), Iron (Fe) and Zinc (Zn)) in primary hair-plasma of Pomeranian (n=10) and Labrador (n=10) dogs were evaluated. It has been observed that correlation coefficients of Cu and Zn in primary hair-plasma of Pomeranian and Labrador dogs were signifi cant at 5% and 1% level whereas nonsignificant (p<0.05) in both the breed of dogs for Fe.
