Growly-dog never had fleas before. Now I am not certain that he has them now, but he has little bits of black something-or-other in his fur (stuck quite low down - I thought it was just filth and was pulling it out) but last night I noticed a small black scurrying thing on his tummy.
Now he isn't scratching that much (and neither are we) and I noticed the black stuff ages ago so I would've thought had he been infested with fleas that one of us would have had the odd bite (he sits on the sofas etc so I would've thought they would be everywhere).
Plus I thought fleas were brown colour. And jumped not scurried?
Frontlined him last night, but will that kill everything small and beastly?
