A Wide Array Of Factors Can Influence Progesterone Levels In Dogs, Reflecting The Complexity Of Their Endocrine System And Reproductive Health. Here Is A Comprehensive Overview

Ovarian issues: Abnormal ovarian function or inability of follicles to develop normally can lead to decreased progesterone levels.

Physiological problems: Dogs may suffer from endometriosis, uterine fibroids, and other physiological issues that can affect progesterone secretion.

Pregnancy issues: Abnormal embryo development during pregnancy can also lead to decreased progesterone levels.

Malnutrition: Deficiencies in protein and fat, especially, can affect progesterone secretion in dogs.

Drug influence: Certain medications may alter hormonal levels in dogs, leading to changes in progesterone levels.

Thyroid problems: Abnormal thyroid function can also affect progesterone secretion, as the thyroid gland regulates many hormones in the body.

Adrenal issues: The adrenal glands, which are involved in hormone secretion in dogs, can cause decreased progesterone levels if their function is abnormal.

Stress: Stress in dogs can also affect progesterone secretion, as it can influence hormone levels in the body.

Other diseases: Diseases affecting other organs in the dog’s body, such as the liver, kidneys, and others, can also affect progesterone secretion.

Additionally, pseudopregnancy (false pregnancy) can also lead to changes in progesterone levels. Pseudopregnancy is a physiological phenomenon that occurs during the inter-estrus period (the time between one estrus cycle ending and the next beginning), characterized by a decrease in progesterone concentration and an increase in prolactin concentration. Conditions such as luteal disease, endometritis, uterine effusion, and pyometra can also lead to abnormal secretions, resulting in pseudopregnancy-like symptoms in dogs.

It’s important to note that these factors may not always absolutely affect progesterone levels in dogs, and the specific situation needs to be considered based on the dog’s overall health, age, lifestyle, and other factors. If there are concerns about abnormal progesterone levels in a dog, it is recommended to consult with a veterinarian for professional diagnosis and treatment.
