With our Husky, she needed essential fatty acids (fish oil) to help get rid of the stiffness in her joints.
Our springer/pointer seems to have allergies. These improved with fish oil and Lugol's in her water. She's not 100% yet, but it's only been a week, so time will tell. She has the choice of pure water and water w/Lugol's. Sometimes she chooses the pure water. I don't think she touched the Lugol's water yesterday, but the first two days she drank it down immediately, and she drank some today.
The patches on her elbows are getting smaller. Now to find a way to make her less attractive to the ticks without exposing the whole family to chemicals......
