Injury. Booklice feed on molds and will overrun cereals and similar materials that support mold growth. Their presence, therefore, is a nuisance and can render some foods unfit. The starchy paste of wallpaper and books also can support mold growth or may be attacked directly by booklice.
Special Notes. In young dogs, hip dysplasia usually is caused by conformational abnormalities that cause a âpoor fitâ between the head of the femur and the pelvic acetabulum, which in turn causes laxity of the hip joint.
Following are some symptoms suggesting hip dysplasia: Decreased activity. Difficulty getting up from laying down. Rear leg pain. Reluctance to use stairs to go up. Reluctance to jump up or stand on hind limbs. Reduced range of motion. Bunny-hopping gait when running.
