Hi,
Since my daughter is out of town, I'm "babysitting" her dog. I work during the week so I take him to doggie daycare. I treat him monthly with the Advantage I get from the vet's office and yet I'm noticing he's still a flea bag since going to daycare.

Is there something else I can additionally give him or put on him? Can you use the Advantage more than once a month?

Any suggestions would be most helpful. While I love this dog dearly, I'm no animal expert.
Thanks,
Okie
