Reuben was given a flea/worm injection by the vet when he was about 12 weeks. At about 7 months he seemed to be scratching so I decided he needed flea treatment.

I had a capsule of Frontline left from my other dog although it was a year or so old.

I used this but he still seemed to be scratching. So I used a flea collar but the same thing happened.

Now I have put flea collars on the 2 cats and am wondering if any cat fleas have got onto Reuben and wont come off because he is wearing a dog flea collar.

I know cat fleas can live on dogs... I was just wondering if it might help if I used a cat flea collar on him for a while as well as his dog one until he is no longer scratching, then take it off?
