Sniffer dog trails if evidence?
Services of a sniffer dog may be taken for the purpose of investigation but its faculties cannot be taken as evidence for the purpose of establishing the guilt of an accused.
Objection against sniffer dog trail:
There are three objections which are usually advanced against reception of the evidence of dog tracking. First since it is manifest that the dog cannot go into the box and give his evidence on oath and consequently submit himself to cross-examination, the dog’s human companion must go into the box and the report the dog’s evidence and this is clearly herersay. Secondly, there is a feeling that in criminal cases the life and liberty of a human being should not be dependent on canine inference.
[Abdul Rajak Murtaja Dafedar v. State of Maharashtra, (1969 (2) SCC 234)]
In another case the objection pertaining to sniffer dog was that the life and liberty of human being should not be made to depend on animals sensibilities and that the possibility of a dog misjudging the smell or mistaking the track cannot be ruled out, for many a time such mistakes have happened. In the said case, Court relying decision in Abdul Rajak Murtaja Dafedar (supra) case held: “We are of the view that criminal courts need not bother much about the evidence based on sniffer dogs due to the inherent frailties adumbrated above, although we cannot disapprove the investigating agency employing such sniffer dogs for helping the investigation to track down criminals.”

It was followed with another case and it was held that “the law in this behalf, therefore, is settled that while the services of a sniffer dog may be taken for the purpose of investigation, its faculties cannot be taken as evidence for the purpose of establishing the guilt of an accused.

Conclusion about sniffer dog in evidence:
Thus the services of a sniffer dog was taken for investigation. The said dog traced the accused and he was formally arrested in the evening of the next day. The Investigating Officer, Ashok Kumar Yadav (PW-10) corroborated the evidence of Abdul Lais Khan (PW-4) to the effect that â€˜Rajaâ€™ sniffer dog after picking up scent from the place of occurrence tracked down the house of the accused. What is relevant to note is that the accused has not been convicted on the ground that the sniffer dog tracked down the house of the accused and barked at him. The evidence of dog tracking only shows how the accused was arrested.
