I've been using this on my sick dog. She is a 11 yr old Rotti Lab mix. She seems to have open Pyometra. I didn't take her to the vet because of her age. Her mom developed the same thing and I took her to the vet when she was 8 years old and they made me do a surgery and she died 2 days later cuz they said she was old etc etc. I decided to try this oreganol oil and it saved this dog. I know with the Pyometra it would release the bacteria in her blood stream which would be fatal. This Oreganol is anti bacterial anti viral and anti fungal so I decided to give it a try. I make 2 green smoothies and feed her 4 times a day and include about 9 drops of oreganol in each mix. I believe if I didn't have this oil she would have been dead already. Its been over 2 weeks since she's been ill but she is slowly doing a little better each day thanks to this oil
