Got excited when I saw this was Large Dog, but it's 21-55lbs. Who considers that large?
Need some for my 85lb-er.

This is NOT the stuff you can share with the kitties. The 'tix' part of the name refers to tick prevention, which uses permethrin. That chemical can make cats very sick or even kill them.

Some dog flea dips have FELINICIDE.

I give you one guess what this does to cats.

I just eyeball half the dose and seal the opening.

Again, this is from my own personal experience (and many others) as my dog is just about too big for the medium dose, and it doesn't make sense how 21lb dogs should use the same dosage as 55lb dogs. I've never seen any flea or tick on the pup.

If you want to be safe, just use a syringe to measure out the full dose and split it.

How can we tell if this is counterfeit? Some posted that Amazon is notorious for fake Frontline which was posted here a few days ago.

In my experience, if something is shipped and sold by Amazon, it's most likely legit. Although, there are some third party sellers with low ratings that you might want to look out for.

In my experience, if it says shipped and sold by amazon it's most likely legit for all product being sold on Amazon. Generally, when you see negative reviews for something being fake, they purchased the same item from a 3rd party seller. But this is just what I have seen.
