The Science Behind Dog Period Stains

Dog blood stains can occur during a female dog's ovulation period. This is because the blood is coming from the dog's uterus and is a sign that the dog is able to reproduce. The reason the blood can stain clothing is because it contains pigments called hemoglobin, which gives blood its red color. When hemoglobin comes into contact with oxygen, it can become oxidized and change color, making it difficult to remove. Additionally, the blood can contain enzymes that can break down fabrics, making the stain harder to remove. Therefore, it is important to clean the stain as soon as possible before it sets in.

What You'll Need To Get Rid Of Dog Period Stains

  • Cold water
  • Laundry detergent or a stain remover specifically designed for blood stains
  • White vinegar or hydrogen peroxide
  • A clean cloth or sponge

Step By Step Process To Remove Dog Period Stains

  1. Blot the stain with a clean cloth or sponge to remove as much of the blood as possible.
  2. Rinse the affected area with cold water. Cold water helps to prevent the blood from setting into the fabric.
  3. Apply a stain remover or laundry detergent specifically designed for blood stains, or a mixture of equal parts white vinegar and water, or hydrogen peroxide, directly onto the stain.
  4. Gently rub the solution into the stain with a clean cloth or sponge.
  5. Let the solution sit for about 10-15 minutes.
  6. Rinse the area with cold water again and then launder the garment in the washing machine on the warmest water temperature recommended on the care label.
  7. Inspect the garment before placing it in the dryer. If the stain is still visible, repeat steps 2-6 before drying the garment.
Please note that If the stain is not completely removed after the first treatment, it may be permanent. Also, when using hydrogen peroxide, be sure to test it on a small, inconspicuous area of the garment first to check for any discoloration or damage. And, always follow the care label instructions on the garment.
