|   No way 
  Flea ciollars are toxic, would not let one anywhere near my boys.  Topical flea protection is the best, I use Revolution which takes care of fleas, mites, mange, ticks(I live in SoCal and have never seen one of those in my life) and heartworm.  And I would NEVER use a Hartz product of any type on my dogs.  Do an internet search on Hartz products and you will see why.  They kill animals.  |
