Dr.Mac,
could you please clarify if dog has to wear it all the time or just when going into the woods? Also how do you apply it tightly to the skin, when shelties have their ruff and hair? I am much liking collar idea as Che REALLY does not like any topicals so collar could be lesser evil specially if one does not have to wear it all the time- we are suburban dogs so ticks are only a possibility when we have an outing and I am not worried about fleas until August
Our position :
Frontline- great for fleas, 'of some value' for ticks.
Preventic Collar- useless for fleas, 'pretty good' for ticks.
Nothing is a good for ticks as Frontline is for fleas. If a dog on Frontline is infested with fleas that is a puzzle and we have to figure out why. But we make it very clear to our clients- 'Don't call me and say 'Yer dang collar didn't work- I found a tick on my dog.'
For Skye, who spends a lot of time in horribly tick infested woods this time of year - with nothing, half a dozen ticks a day. With Frontline, a couple every couple of days, with the collar, a couple each week. This is not only my view, it is the opinion of most veterinarians I know.
Seasons - (Rhode Island perspective)
Ticks- can have problems throughout year - November was big this year, january if no snow cover. However the real 'tick season ' is April May.
Fleas - primarily Aug - Nov (as you say.) Fleas arrive like clockwork on Aug 10. However, given right temp/humidity they can be around earlier. I saw a little Yorkie 2 days ago loaded with fleas.
So - bottom line - Frontline June through November. If you have mild tick exposure start your Frontline in April. If you have heavy tick exposure, collar march through mid June, then start Frontline.
I am tending to switch from Frontline to Comfortis (which claims zero tick protection), though client complaince will make the switch take awhile. For Skye I am switching this year.
Skye's cpllar stays on. She has a rather epic ruff...
and I just place it deep within the ruff, against the skin, loosely around the neck. You can't even see it.
Anyway, that's our practice position and my personal choice. It is certainly not the only 'correct' choice. Hope that helps. - Dr. Mac
