Zebo (RB) used to nip my calf when he was happy or wanted attention. When I had my son I was quite ill so was in the hospital awhile. Zebo had never spent more than one night away from me previous to that. When I got home he was so happy to see me he kept nipping my calf. Then he took a whiff of what I had bundled up in the blankets and ran and hid under the bed for three days!
