I have to say that if we're also talking about wild grasses, my wire fox terrier is also a pollinator. He collects an incredible amount of seeds and burrs during his walkies investigations and I have to pick them out of his fur afterwards (risky because he gets annoyed easily).

Seeds are not gametes. While your dog may help spread the seeds, they are not assisting in the sexual reproduction itself.
