I would recommend that you have Chowper examined by a veterinarian. It is hard to see the pictures since they are a little dark and blurry. I am seeing areas of hair loss, and possibly bruising in the third picture. A common cause of hair loss in young dogs is demodectic mange. This would require treatment with a veterinarian. Other possible causes for hair loss include fleas, lice, infections (bacterial or yeast), ringworm, allergies, among others. A vet can examine the skin and determine what is the cause so that she can be started on the best treatment. A swollen vulva with red discharge can be caused by a dog being in heat or in labor. If her mammary glands are enlarged, then it is possible that she is pregnant, since this does not normally happen in dogs in heat. While it is not common in younger dogs, it is still possible that she has an infection in her uterus (called a pyometra), which would require emergency vet care.
