We are waiting to get a puppy from an Amish farm... he will be 7 weeks when we pick him up. They are all kept in a barn... and I am very concerned about fleas! I have had a flea infestation before... and I do not want any animal with fleas. All the pet medications seem to say to wait until they are 8 weeks old before treating. Is there anything I can do to ensure that I don't bring fleas into my house? As I have dealt with this before, I know flea collars and flea baths just don't work. Any other helpful advice?
