My puppy had the the revolution treatment done, however during his grooming and bath process, some fleas were found around his neck. I took him back to the vet, who did a blood test and recommends further tests, to assure that there are no further disease on home. Not sure if he came from the breeder with fleas. I have tried to clean the house and will continue with the treatment of revolution. I only have him for 5 weeks now and we do not walk far. He is a labradoodle and 18 weeks old. Any suggestions as to after affects and what should my further course of action be.
