Ok thanks, its not my dog, but I keep telling the owners its got fleas and they're always surprised. They said the dog never got fleas before, so thought he was catching it from the cat. Their house is scummy in places not even clean so the fleas probably live in the house. Makes me sad, they've got grown up children who visit, you'd think they'd help. I just wanted to know if the place was likely to be alive with fleas coz I don't want to bring fleas into my house. They treat the dog now (they was using bob martins from tesco but now they got frontline coz I said they should go to the vet) but I don't think they do the cat and they def don't do the house! x
