In terms of helping pets relieve stress and for training purposes, when pets are in the process of sniffing, playing and eating, they will be fully engaged and shift their attention away from some external factors that may cause them to feel nervous or anxious, thus achieving the effect of relaxing both physically and mentally and relieving stress. Moreover, owners can also make use of this pad and cooperate with some simple commands. For example, owners can ask pets to sniff and find a specific item first and then give them rewards to conduct basic obedience training, making pets more docile and obedient and strengthening the interaction and tacit understanding between pets and owners.
