So spring has sprung about everywhere and with it comes the bugs.  I can tell you here in FL it is the fleas, ticks and heartworm carrying mosquito's.  As much as I hate to put chemicals on my buddy Case, he has to have some protection.  I use the advanticks because it is also waterproof and stays on even after swimming.  What do you all use to protect your friends?   I am stuck with the heartworm pills but would sure love to have tosomething more natural to deal with the fleas and ticks.
