Yikes, I’ve seen a bug in Breintjes fur for the 3rd time now. We got a very fine-toothed flea comb ASAP, but I can’t seem to catch the bug with it. Sometimes it just runs in front of the comb. Breintje shows no signs of discomfort, but I find it repulsive that something’s in his fur 
Things ruled out so far:
He has no black flakes which turn red in water, like you’d expect from fleas
No white/yellowish dander like you’d expect from mites
No fur loss
No visible skin irritation
No extreme itching
What I have seen:
3 sightings of 1 single bug, impossible to say if it’s the same one. It’s about 2 mm long with an elongated body. It has a very dark shiny black carapace and it runs through his fur. It doesn’t hop, but it runs very quickly. I can’t catch it with the comb and it’s too fast to catch with a piece of tape. I was hoping to catch one to take it to the vet, but I just can’t catch one. I’m combing Breintje twice a day now, but I see the bug only occasionally.
Does anyone recognise the type of bug?
