DogTV review: Channel on smart tv

I tried a "free" trial period of Dogtv. I found it to be ridiculous and my dog had no interest. Now I want to cancel it. The option of cancelling or unsubscribing is nowhere to be found on the app that I downloaded to my smart tv. When I put in a verbal search for "cancel dogtv," it says I purchased through Amazon which I did NOT. Cannot find anywhere that allows me to cancel/unsubscribe. Their website is deceiving and, after reading the horror stories of people who had to fight to cancel their subscription, I need to be able to unsubscribe ASAP.
