[Is what a dog needs a ball or a snack?] How does my dog feel? Dogs express a lot of emotions through barking. But it's hard for us to know why dogs bark. Is there any easier way to understand the dog's mind? Wouldn't the dog alone feel anxious? It's hard to know just by looking at it through CCTV. Is the dog doing the right amount of exercise every day? Can you know how many calories the dog burned through exercise? All of this can be solved with a Petpuls. ■Real-time timeline function. - Y
