Money well spent
My dogs were picking up several ticks on every single walk and we were finding them in the house. We also had a major flea issue last year too, despite regular flea tablets, and had to flea bomb the whole house to get rid of them. So we bought these collars 2 months ago and there has not been a single tick since! And as the weather warmed up we didn't see any fleas either. Definitely works well for my spaniels!
