You can't. This is a medical procedure that has to be performed by a professional.
Fix-it
It could be Iodine, which is a purple/blue antiseptic. By fix I assume you meant that you dog had been to a vet?
There are vets that fix dog teeth when broken.
yes but you can fix it by killing the dog
Slap it around
Take it to the vet
tape it
jackhammer it in the face
cuts his balls off
I will assume by "fix" you mean spay. When a vet spays a female dog, she surgically opens the dog's abdomen and removes the dog's reproductive organs (ovaries and uterus).
Go to the doctor????????
dogs never ever have periods
