Breeding success starts with science! ✨🐶 Did you know that tracking your dog's progesterone levels can be the key to a successful breeding process? 📊 Why is progesterone testing important? ✔️ It helps pinpoint the exact time for mating or insemination. ✔️ Dogs ovulate when progesterone reaches 5-8 ng/ml, but the best time for fertilization is a couple of days later when levels hit 10-20 ng/ml. #bellylabs #tobesure #dogbreeder #breeder #dogpregnancytest #bellylabslitter #bellylabspregnancy #dog
