It’s a big, soft brownish pill? That’s what I had to get last year, and it was very effective. After a couple hours, you can see the fleas abandoning ship like mad! Need to give the dog a bath the next day to get the millions of fleas off the pooch.
I had to smush mine up and mix it into a piece of cheese to get the dog to eat it.
Sorry, can’t remember what it’s called, but the vet will know by the description.
Thats the one. I just stuffed it down the cats throat and it worked a treat. He wasnt too happy at the time, but hes stopped scratching now.
