my 10 mo old black lab has been acting strange for a few days now- i'm not sure if it's separation anxiety since he's not displaying the main symptoms i've read about (and seen in other dogs). since friday, he has started to hate his kennel. what used to be his sanctuary he new refuses to enter. when in there he rips up his bed and pees a little. he wants to sleep by the front door. this morning he snuck into my car which he's deathly afraid of, and refused to leave it. any ideas? he might miss my now ex gf (his mommy), but she's been gone for weeks- why now?
