My dogs always licking her vagina...

Question
I think she lost her virginity to my friends dog when I asked her to watch my dog. She is a Pekignese and is 1 and a half years old. When I got her back from my friends house she was really tired and didn't really eat or play. Then she started licking her vagina and dragging  her vagina on the carpet. I tried looking at it and it has a black color on the bottom of her hole in her vagina...what do i do?

Answer
Dogs do not lose their virginity unless they are in heat. If your dog is in heat she will have a discharge and swelling for three weeks or so. You need to visit your vet. If she's been bred she needs to be healthy to raise healthy pups. If the dog that bred her was much larger the pregnancy should be terminated and she should be spayed. Once determination is made, she should be spayed regardless. She might also have an infection. Take her immediately to your vet for diagnoses and treatment. Keep me appraised of her situation
