dogs will eat grass if their tummy's are upset. Others eat it just because it is there. However, if you have used any fertilizer, weed & feed, or other lawn products it could be that is what is making him sick.
If it were me, I'd not give him any more treats for a few days and see if he improves, could be he is sensitive to whatever is in the treats. I'd also call my vet ASAP so that he is aware of the situation. |
