I don't do topicals, just me, I don't like putting anymore into them than I have to.
If you dont have a flea issue, don't treat is my feeling, kinda like if it ain't broke dont fix it? Ticks, not sure of your area, but again, I don't treat topically..if I go for a hike in the woods, I spray them down with a little Natural Defense..
HW, my gsd is on heartguard plus, my aussie is on interceptor monthly...Since my aussie is 14 yrs old, and interceptor is basically non existent, don't know what I will do for her next year..I have a few left, not sure it will get me thru the season..I do HW from april 1 thru Dec 1.. Jerry Lee is a LOOKER!!!
