The proper function of urinary tract tissue is dependent upon adequate exposure to estrogen and after a pet's ovaries are removed, her estrogen levels are low. Lack of estrogen may cause the urethral sphincter (a muscle used to control the exit of urine) to relax and release urine involuntarily.11-Mar-2021
Estrogen is the hormone that controls sexual development, behavior and reproduction in female dogs. However, estrogen is produced in both male and female dogs. Overproduction of estrogen can cause complications of the reproductive organs and even estrogen toxicity, known as hyperestrogenism.
Toxic consumption: In dogs, greater than 1 mg/kg (0.45 mg/lb) of estrogen may be toxic. It should be noted that oral contraceptives typically contain 0.02-0.05mg of estrogen per tablet.05-Mar-2020
Hormone replacement therapy in dogs is a lifelong commitment as these drugs serve to replace estrogen that would have otherwise been produced in an intact female. Sometimes dogs begin to show signs of incontinence even while on this therapy. In that case, the dose will have to be increased.
In an unspayed dog, the ovaries produce a number of hormones, including estrogen. It is this estrogen that triggers your dog to go into heat. When your pet is spayed, the entire reproductive tract (including both ovaries and the uterus) is surgically removed.
One common cause is hormone imbalance following spay surgery. The proper function of urinary tract tissue is dependent upon adequate exposure to estrogen and after a pet's ovaries are removed, her estrogen levels are low.11-Mar-2021
Estradiol has a high risk of causing endometrial hyperplasia and pyometra. There is a dose-dependent risk of bone marrow toxicity in animals, particularly in dogs. Estradiol cypionate injections have produced leukopenia, thrombocytopenia, and fatal aplastic anemia.
The US Food and Drug Administration (FDA) last week approved Proin ER (phenylpropanolamine hydrochloride extended release), a tablet for the control of urinary incontinence in dogs. The drug will aid with urethral sphincter hypotonus, which occurs due to a dog's age and weakening muscles in the urethra.08-Apr-2019
