I was thinking the same thing How much of the horse kind do you give your dog?
The lable said to double the dosage for the first 2 weeks, so I started Mick out with 1/4 tsp a day, then dropped it to 1/8. The last year or so of his life, I went back to 1/4 tsp (after talking to my vet about it). Mick weighed 75 pounds when I started the ArthriSoothe. He lost about 10 pounds over his last 4 years due to muscle loss from laryngeal paralysis. My vet & I are convinced that, besides helping with old age stiffness, etc, the ArthriSoothe helped slow down the progression of the LP.
