I have brought 2 lots of these, as the scent dissipated after 6 months, so they were only 4 months old when 2 of my three dogs had paralysis ticks. One above his eye and the other under his eye and on his lip. Both had severe reactions to the tick bite and one had to be admitted to the emergency vet because he was having trouble breathing. Luckily, we found one and the vet found the other. Anti venom, antihistamines, sedation, oxygen and a $5500, 24 hour vet bill later, he survived. Not at all impressed with FurLife, the product did NOT deter ticks from latching onto my 2 5 kilo and 5.5 kilo dogs.
I purchased these in hope to deter ticks from latching onto my dogs, after losing my dog Mouse last year to a paralysis tick that we, the veterinary and the veterinary nurses never found. 😓
