M.C.
We had a problem. We gave the dog a treatment and then the next day, without thinking, the dog got tossed into the pool so that he could swim with the kids!!! Once given the treatment, the dog should not get wet or washed for around 2 weeks.
We have 2 kids, one with asthma so bombing wasn't an option. We talked to the vet, they gave us another treatment that was different so that there was no interaction.
The vet also told us, like MamaMay, to buy a weeks worth of cheap flea collars. Put one in the vacuum bag and vacuum the whole house every day for a week. Change the bag when you are done. This gets the eggs that are not effected by the flea bomb. Worked wonderfully.
