Germ smart dog toy. BioCote protected. A more hygienic toy for your pet and your family. BioCote is an antimicrobial technology. An antimicrobial is something which prevents the growth and survival of microbes including bacteria, mould and fungi. Lower levels of bacteria mean improved hygiene, reductions in staining and odours and premature degradation of materials. BioCote technology will, therefore, make this product more hygienic, keep it fresher for longer and extend the usable lifetime of this product. Massages gums and reduces plaque and tartar buildup, constructed out of tough yet soft plastics, is treated with a zesty fruit scent and even floats too! Pack the orange segments with small treats or some wet food. Your dog will love the challenge of trying to extract the treats!
