i would remove the ticks gareth ,get a 0`tom tick remover , they make it simple to get them out . when dosing with frontline after they are already on the dog ,they take a few days to drop off , and i always think with all the nasties they carry ,its best to get them off straight away . ive found frontline only gives a few weeks protection against ticks . ive had the same problem with the yellow puss spots , ive put it down to either nettles or grass , ive found that diluted tcp clears it up within days . atb robo
