No. If your pet eats a few grass blades, then the amount of chemical on them is not enough to harm them. They would have to consume a large amount to have any kind of effect.
The acute poisoning symptoms are basic - diarreaha, vomiting, lethargic behavior, etc. If your pet has any of these, then a trip to the vet is probably in order.
