Idea Exchange: Place red rubber urethral catheters more easily
Red rubber urethral catheters can be difficult to place in female dogs since the catheters are not as rigid as polypropylene catheters. But polypropylene can be traumatic. A polypropylene catheter makes a great stylet for the red rubber catheters, however, if you use a polypropylene catheter one or two sizes smaller than the red rubber catheter.
