I'm thankful that none of our animal have separation anxiety....however Spencer can come close. He absolutely hates when I take Viking on a run and leave him at home. I can hear him for blocks while he howls. Even if I leave and David's still home, he howls. Hopefully someday he'll put two and two together and realize that he gets his turn too....he just has to wait until I get back with Vike. This video doesn't give him justice, but you'll get the gist. After I left, with Viking, for a run this morning, Spencer started to howl. This was after he had wound down a bit, so he wasn't going nonstop. Parts of it includes David howling too. Even so, it's quite cute. David thinks he's saying, "I want/love my mommy!" That or "Ah Wooooo Woo Woo Woo Woo Hm!" What do you think he's saying???
