“Whilst I think this product is the best by far for treatment of ticks, I have had a couple of problems with the collar itself.
One time the collar had tightened so much it was choking my dog, thankfully her struggles with getting her breath woke me.
The other time I could not get the collar off for her grooming and I had to cut the collar off.
But overall in all the time I’ve used it these have only been one offs.”
