This is a picture of the Biceps Femoris in a dog. This muscle is partly responsible for extension of the hind limb. Especially in Agility dogs this is especially important. Stretching this muscle is very important. if the pelvis is locked up [subluxation] at the sacroiliac joint then this muscle will be tight and restrict extension and thus slow the dog down and shorten stride. Having chiropractic adjustments with muscle work will improve this issue.
