Megan started holding one of her back legs up Saturday. At first I thought maybe she sprained her leg when she was out running around but Sunday morning when we got up one of her toes on that leg is about 3 times its normal size, pink to reddish in color and warm to the touch and the foot itself is also swallen. So Sunday we gave her benadryl all day hoping it would help bring the swallen down, no luck. So this afteroon at 2:15pm we go to the vets to see what is wrong. Wish us luck. Somehow I think we will need it.
