A few years ago I got into homeopathy treatments for dogs.
For Annie after her shots the vet used Thuja 30c to help clear the affects of the shot to her system. It worked wonders! She didn't get the usual lump or symptoms of any sickness.
She was also diagnosed with liver cancer when she was about 8 or 9. We started her on a raw diet and homeopathy. She lived to be 13.5!
She finally walked over the rainbow bridge in march. She is definitely missed.
A wonderful book I would recommend for those interested in working with natural remedies is: Natural Healing for Dogs & Cats by Diane Stein
There are many other wonderful books out there about alternative medicine.
Happy healing
