For years I use this collar for my cats and a just such is also available for dogs. Even my dog is wearing it. We live in the countryside and have 5,500 sqm garden. There is plenty of vermin. In the spring and I entwurme entflohe the animals thoroughly Milbemaxtabletten (also against tapeworms) and Frontline in the neck or Advantage or Advocat (neck, against all worms, ear mites, lice, etc.) + 1/2 Tbl.Bandex (Tapeworms need extra fought in the two funds latter). Then they carry the Beapharhalsband. It affects 4-5 Monate.Im summer there is a new to late autumn. In winter wear my no collar. Never have ticks or fleas. The tape is odorless, lit up at night, has breaking points, so that the animals Do not choke when imposing. It is cheap and extremely effective. Making Quiet firmly around the neck, so that you can still grab a finger in between. To loose it quickly lost or slipping while brushing with a paw into it and then run with the belt around his neck and "shoulder" around. Easy to remove With tame cats but in timid, then get too scared not so easy to bring the misplaced collar back in order. I love these collars, so my recommendation BUY !!!!
