EM ceramic anti-tick dog collar is a great natural alternative to chemical collars, it can be as effective as any tick treatment found on the market but without the toxic chemicals and side effects, making it safe, especially for dogs with allergies and sensitivities. The collar is safe if you have children in the house, but do not let them eat the beads. Portuguese cork is vegan, waterproof, moul
d resistant, stain resistant, scratch proof and anti allergic. It is 100% chemical free. It is tough and strong, but soft to the touch. No waste is produced in the extraction, processing and production of the cork so it is eco friendly. Only natural dyes are used. EM ceramics is a Japanese discovery, it comes in the form of a bead composed of clay to which effective Microorganisms (EM) have been added during firing. This firing allows the EM to settle in the clay and last. These Microorganisms are activated by water, movement and sunshine, and transmit vibrations, (magnetic resonances), this is not noticeable to us or your pet, but is unpleasant for ticks and other small insects. There is no 100% guarantee with EM collars or any other tick product, you should always check your dog AND yourself after a nature walk. The collars are 100% custom handmade to fit your dog and as a result I can not offer a refund or exchange. The EM collar is not strong enough to be used as a collar for a lead, so please don't attach one. To Measure, please refer to the photo, place a measuring tape around your dogs neck with 2-3 fingers underneath. The measurement above the head is to ensure that the collar fits over the dogs head. There is some adjust ability in the collar, so when ordering please choose the measurement nearest to your dogs neck size. Please state your colour of choice. It is recommended that you replace the collar every 10-12 months.
