Billy No Mates! is a safe and natural 'easy-to-use' herb mix in tincture form with no nasty chemicals. Just blend the aromatic combination of mint, seaweed, fenugreek, neem leaves and lemon balm into your dog or cat's food. Or add to your pet's food or treat. Billy No Mates! is also great for skin and coat condition. BNM suggest use from early March to help ensure your dog is 'protected' but can be used effectively all year round. BNM also recommend a short break to ensure the efficacy of this natural product. Please allow 4 - 6 weeks for your dog to be protected against any unwanted passengers.
