Poison is poison.
Yes this works. No ticks. But also almost no dog as well.
Major skin reaction on ears and neck. Wish I took pictures. Bleeding etc.
Even the vet thought it was mites etc. nobody wanted to blame the collar.
But I took it off, despite living in tick central, and a week later it all cleared up.
Proof enough for me.
Poison is poison.
