Absolutely stop giving trifexis it is deadly for all dogs but even more so for small dogs! I'm not sure there is much you can give at 8 weeks but within 48 hours of getting a pup they need a vet appointment so speak with the vet about it. At 8 weeks they really shouldn't be using other areas where dogs and wild life got outside until he has at least 2 sets of shots.
