Oh boy I know dogs howl but my little one never did. He heard different songs playing but never did it. I thought I guess my baby doesnt sing until one day... After going to the park few days ago it was very warm here it was like 60F so I had to take the opportunity and take him to the park. On the way back he was tired and was sleeping in his carseat. All of the sudden my phone rang... I have this funny ringtone set up only when my grandparents call me, I didnt want to pick up because I was driving. To my surprise Maxi got up and started howling!! I couldnt believe it it was soooo cute!!! Who could of thought that this crazy funny ringtone will trigger him!
