Superhuman speed: Skinwalkers, in their dog form, can run and move faster than mortals.

Superhuman senses: Their sense of sight, hearing and smell is greater than that of a mortal, even in their mortal form. They can see objects within a distance of approximently 500-600 metres and can see better in darkness than a mortal could, hear far beyond the limit and four times the distance of a mortal can, smell and detect if they are being followed, with a range of 100 metres.

Infectious bite: Bitten by a skinwalker will cause an infection on anyone who is bitten, and the victim will eventually go through a transition into a skinwalker within 24 hours.

Weaknesses
Silver - Sliver is lethal towards skinwalkers, as such, if stabbed by a silver weapon, the skinwalker will die. A Skinwalkers skin will also burn upon contact and will change to their mortal form if wounded by silver.

Magic - Skinwalkers are vulnerable to magic, as it can harm them or possibly kill them (never been shown). Magic can also be used to cure them from their skinwalker infection, as shown with Oliver, who decided to cure a skinwalker rather than kill it.
