A puppy has been caught red-handed! His reaction? Unmissable!
When dogs are left alone, they enjoy doing everything that you have taught them not to do! Therefore, they immediately tear off and shred toilet paper, chew on shoes, destroy clothes or any object that they know is dear to you! Why? Perhaps to reproach and punish you for not having taken them with you when you left the house! Who knows!?
In any case, in the video, when this puppy is discovered shredding toilet paper with its teeth, it does not have the usual culprit reaction of guilt and remorse! No, actually, it seems almost angry to have been interrupted! A ninja dog? :)
