They are all pesticides, if you read and compare the ingredients with similar products, you won’t see much difference.
Unfortunately, we need these products to combat Lyme and fleas….diseases they carry.
Some products may agree with an individual dog better than another.
See what your vet recommends. It depends on how bad the ticks/fleas are in your area.
I find avoidance (tall grass, woods) goes a long way to help, too.
I am leery of the new oral agents, however, I just don’t trust them.
PS: The “natural” stuff doesn’t work.
I use a flea/tick shampoo on my senior dog, about every week or two in the summer, I figure it’s milder than the topicals….plus he got a rash from a amitraz collar, although my other dogs tolerate the collars fine.
