If it's not one thing it's another! Just had dogs groomed and was told one of them has fleas. Its obviously not bad enough for us to notice. I was a week late with the advocate, and we'd been to a holiday rental during that time so I can see how it happened. My question is this: I put the advocate on both immediately but do I have to do anything in the house? (And i tried googling but kept seeing pics and it's made me feel like my skin is crawling! )
