This morning when my dad let my lab out in the garden...he went to eat leaves and almost vomitted again~!!! But he didn't coz i think his stomach was emtpy this morning...if he has eaten something before that...i think he'll vomitt ler...
This may be no significance, or it may indicate irrition in the stomach. It is believed that a dog instinctively takes grass to induce vomitting. Grass wraps itself around jagged foreign bodies in the stomach, so helping to prevent damage to the bowel.
