PATENTED MICRO-INJECTION TECHNOLOGY WILL KEEP YOUR DOG SAFE! Unlike other low-quality tick and flea collars for dogs, we have utilized a UNIQUE Israeli patented Micro-Injection technology to infuse essential oils into the dog tick collar. As a result, the essential oils will be released via the special pores in the plastic using a Slow-Release process, which will make the natural tick and flea collars more effective! THE SAFEST FLEA & TICK COLLAR FOR DOGS IS FINALLY HERE! Arava flea and tick control collar contains natural ingredients only. Thats why our waterproof and adjustable tick collar for dogs isnt only safe for your furry friend, but also safe for you and your children! SOOTHING NATURAL SCENT WILL REPEL TICKS & FLEAS FROM YOUR PET! Our waterproof and rainproof natural flea and tick collar for dogs has a light and soothing essential oil scent that will help keep fleas and ticks at bay. We use only natural essential oils, so if you feel like the scent is overwhelming at first, you can leave the collar out for 24-48 hours and then use it on your doggy!
