whenever someone isn't here for at least 5 minutes and comes home, my dog (Lulu) runs to them and jumps on them excitedly, she also whines a lot, is this a puppy thing? I was too young to remember if Chloe did this, or Dexter (an old dog we sold when I was a baby for no reason my parents will tell me, they told us he became roadkill until they told us the truth)
