The collar stinks, in the first weeks after strong chemistry, but it helps !!! My cats are outdoor cats and they do not mind the smell, I just hope that it does not make any health problems in our dogs and us. But fleas and ticks are also harmful. Alternatively, there are the regular trickling in the neck but this mostly affects just 3 weeks against ticks. In a collar it comes true also that a tick sitting in fur, but she dies, if it determines bites. So I can remove them quickly without this becomes saturated. In addition, the trickling is very expensive, I have every time to the vet to get supplies, which is annoying and the collars are much cheaper.
