Sorry, I don't think this is the right place to post this but since we were already discussing flea treatments I figured I would update you. I had bf pick something up quick for Lennox's fleas, but was scared to use it and I am glad I did not. It was Hartz, and I read some bad things about their line of products online. We plan on returning the Hartz and picking up the Orange Frontline Plus pack tomorrow or Monday.
Hey BetsyB...am I understanding this correctly that you can give them this internally and it will repel fleas/ticks externally?
