When it is a matter of using either a dog catheter or bladder expression in treating the urinary problems of dogs, making a selection is very important. These dog catheters drain urine from these pets in a sterile manner and therefore are very effective for the pets with chronic urinary problems. On the other hand, bladder expression can be appropriate in a number of cases but it has implications of injuries and poses a great deal of discomfort. It is because of knowing these two methods which enable veterinarians in making decisions affecting the health and wellness of the pets in informed ways.
