How does phenylpropanolamine work in dogs? In veterinary medicine, phenylpropanolamine is used almost exclusively for the control of urinary incontinence in dogs and occasionally in cats. Phenylpropanolamine is able to increase sphincter tone in the urethra thus curtailing inadvertent urine leakage.

How much phenylpropanolamine can I give my dog? The recommended dosage of Phenylpropanolamine for dogs is between 0.4 and 0.8 mg per pound of body weight (0.8 to 1.7 mg/kg) every 12 hours (twice daily).

Why phenylpropanolamine is banned? Phenylpropanolamine has been taken off the market in the United States because of the increased risk of hemorrhagic stroke in women associated with its use as an appetite suppressant.

Are there any side effects to Proin for dogs? The Proin dosage for dogs is calculated according to the dog’s body weight and in consultation with a vet. Possible side effects include hyperactivity, restlessness, vomiting, diarrhea, decreased appetite, hypertension, urination problems, difficulty breathing, etc.
