People with animal heads are mythic. They've been used as depictions of the gods for millennia (most famously by the Egyptians), and people have generally seen such depictions quite frequently. It's hard for me to think of such a chimera as being disturbing rather than reverential.
Animals with people's heads, on the other hand, are just creepy.
Or were you thinking of a human body with a dog's head and a dog's mind? That might be a little more disturbing, but as it would have difficulty mastering bipedal locomotion, it would be easy enough to evade that it wouldn't be scary.
