"K9 Advantix seems to be working. Neither of my dogs has had any fleas or ticks on them since I started the medication. (In the past I had only found one tick on them without the medicine though.) We do live about 2 houses away from a forrest in Illinois and there are deer that run through it.
The only problem I had with the medicine is that there is a lot in the tube and its hard to get it all to soak up in the dogs skin. I applied it in 3 places on the skin and in each place there was so much that the fur was saturated too. Both of the dogs tried to lick it off, but I know some was soaked up into the skin.
My only concern with this and many flea/tick topical meds is that it says in the directions that the medicine should not contact your skin and if so wash for a long period of time...and call poision control. It also says do not get any of it in the water supply, as it is very toxic for fish......if the product is that bad for us and other creatures....how is it ok for our dogs???"
