Simple answer is no.
Complicated answer is that no one has free will. Often our subconscious mind makes decisions before you're even aware you've made them for yourself. Outside factors can of course change your opinion, but only because your subconscious opinion has been changed by this external information. As intelligent as we like to think we are, both humans and dogs are conditioned to follow basic patters as well as societal/external expectations. Dogs and humans both seek comfort in seeking patters.
As Sam Harris puts it:
"Free will is an illusion. Our wills are simply not of our own making. Thoughts and intentions emerge from background causes of which we are unaware and over which we exert no conscious control. We do not have the freedom we think we have."
