What is the pill DES for dogs used for?

Diethylstilbestrol (DES) is a synthetic estrogen that was once commonly used in veterinary medicine to prevent pregnancy in dogs and cats. However, its use has been largely discontinued due to its potential for serious side effects, including cancer, reproductive problems, and bone marrow suppression.

DES is still occasionally used in veterinary medicine to treat certain conditions, such as estrus suppression in dogs and cats, and to prevent mammary tumors in bitches. However, it is important to note that DES is a potent drug that should only be used under the supervision of a veterinarian.

DES is typically given orally in the form of a tablet or capsule. The dosage and duration of treatment will vary depending on the condition being treated.

Some of the potential side effects of DES in dogs include:

* Cancer, including mammary tumors, uterine cancer, and vaginal cancer

* Reproductive problems, such as infertility, menstrual irregularities, and abortion

* Bone marrow suppression, which can lead to anemia, leukopenia, and thrombocytopenia

* Other side effects, such as weight gain, lethargy, and vomiting

If you are considering using DES to treat your dog, it is important to discuss the risks and benefits of this drug with your veterinarian.
