did you ever order your frontline off the web? there was a period of time where there was counterfeit product out there. may still be out there.I've read that you can pick up bacteria related tick disease if you crush them with your fingers.
I hate them f ing things.
With a warm winter you'll see them for sure.
Birds can also carry them.
After I bagged a pheasant in January with a foot of snow on the ground I found one crawling on my sleeve.
My dog was diagnose with lyme disease about 3 yrs or 4 yrs ago and this past year tests showed he had some kidney damage. Lyme is known to cause that.
He also had wrist joint problems and joint fluid taps showed fluid build up and inflammation consistent with being caused by lyme.
I think he got it during that warm winter we had about 3 or 4 years ago.
I would find ticks on my dog and myself into the middle of January and February that year.
Look at the CDC map.
I think the disease and tick related disease problem is underreported and under diagnosed.
I also think allot of the tick control products for dogs are more toxic than is reported especially for long term use.
I used Frontline Plus and I'd still find engorged ticks on my dog.
It stopped working for fleas too.
I think the frontline also made my dog have mini seizures.
Hard to figure what's the best thing to do.
I found this article about tick control methods by folks in Maine interesting
