Can you spade your dog if she just mated?

No, spaying a dog after she has mated will not terminate the pregnancy. Spaying involves the surgical removal of the uterus and ovaries, and once a female dog has been impregnated, the fertilized eggs will implant in the lining of the uterus and begin to develop into puppies. Spaying at this stage would terminate the pregnancy but can lead to complications as the body is not prepared for expulsion. It's important to discuss pregnancy and spaying with a veterinarian for the best advice.
