With all the same efficacy as Proin Extended-Release Flavored Tablets, these tablets work by helping to tighten the bladder and urethral muscles to prevent urine leaking and accidents. And since they come in a tablet form, you can feed them to your pet by mouth or disguise them inside a tasty pill pocket.

Proudly sourced directly from the manufacturer or their approved distributor. Guaranteed genuine and backed by the manufacturer.


For the control of urinary incontinence due to urethral sphincter hypotonus in dogs.
