The last few weeks Samson has been following my hubby around and biting at his feet and the bottom of his jeans. He only does it to my hubby, when my husband stops walking samson just stands there staring at his feet like he's waiting for them to move again. Any ideas on why he's doing this? I am not sure if it's just a game to him or he's trying to make sure that he doesn't leave him again. My hubby works 10-12 hour days 5-6 days a week.
