he function of muscles is to provide movement to the dog’s body. Muscles are made up of two types smooth and striated. Smooth muscles are within the internal organs i.e. intestines, stomach and bladder. The dog cannot voluntary or consciously control these muscles or the cardiac muscles. Skeletal muscles are under conscious control they aid walking, eating or wagging the tail also eye movement, head movement etc.. The dog can control skeletal muscle which can be contracted or relaxed at will. Most muscles consist of bundle of long cells & muscle fibre. Muscles attached to the bones by tendons. The stomach has a very thin covering of muscle. Thigh muscles give explosive energy for chasing. The Hip muscles support the back legs. Tail muscles allow the tail to raise, curl and wag. The neck muscles let the head turn over 220 degrees. Extrinsic muscles are those that you see and are voluntary muscles. The intrinsic muscles control the internal force and action, and extrinsic muscles provide range of movement.
