can i give my dog tea tree oil
Research shows tea tree oil is safe for dogs and cats and effective only when it is diluted correctly â i.e., diluted in large amounts of water. The recommended ratio is 0.1-1.0 percent strength, to be dispensed topically. Tea tree oil also is used to effectively treat similar maladies in pets, but recent reports indicate it can be harmful to dogs and cats if used at 100 percent strength. 2  After full-strength tea tree oil treatment, studies indicate symptoms in dogs and cats can range from depression and weakness to vomiting and collapse.
