Query: BEWARE SMALL DOG OWNERS!!!!!!

I have to warn small dog owners about using this product without researching the ingredients. Yes, it is all natural but did you know that rosemary oil can be lethal to small dogs? It can cause seizures. Our mini dachshund had a full blown seizure within a week of starting this product. PLEASE, for your friends sake, do not use this product until you read the warnings on using herbal oils in dog treatments or food. I cannot prove that this product caused the seizure but the dog has had no such episodes in his four years of life. He is healthy and full of life. I will not continue using this product on my dogs after reading the effects and dangers of essential oils, specifically rosemary oil, in dog treatments and food. Essential oils are much too concentrated and are nothing like the whole plant. A drop of essential oil is 100 times stronger than a pinch of the herb plant. This product may work great but I will not risk my pet's well being for the sake of a quick fix.
