Human-grade MSM (methylsulfonylmethane) supplement is a natural option that can be used to treat a variety of ailments including arthritis and joint pain, inflammation (including those from allergens), as well as enhance the immune system. Most high quality joint supplements contain MSM, but these are often at very low levels for it to be hugely beneficial.

This pure supplement can be added directly to your dog's dinner every evening to promote good health or for a shorter period post injury to enhance recovery rates. 

The therapeutic dosage for dogs is about 50 to 100 mg MSM per 5 kg of body weight.
