The dog offers no resistance to the passage of the instrument

The dog offers no resistance to the passage of the instrument. I have never known one to cry, or seen one exhibit a struggle. I could not account for this by attributing it to any fondness for the necessary restraint, under which the creature is temporarily placed. During the flowing of the urine, the dog invariably remains perfectly quiet; and the relief afforded seems to dispose it almost to sleep; for after it is over, the animal lies in a kind of happy lethargy. The fluid, however, does not jet forth or empty quickly. The operator must not be impatient, for the stream is perfectly passive; since, in consequence of the distension, the bladder has lost its contractive power. To obtain the whole of the contents, has sometimes required a quarter of an hour, and the quantity procured has frequently been quite disproportioned to the size of the patient. From a small petted spaniel, brought under my notice by my friend, Mr. Henderson, I extracted very nearly half a pint of urine, and the animal from that period began to get well. From a very small dog, the property of a lady of fortune, I for several days, every night and morning, withdrew about four ounces of the excretion with marked benefit to the animal. The operation is tedious, but it repays us for the time it occupies. Towards the conclusion the stream is frequently interrupted. It stops, then recommences; ceases, and then begins again; and the last portions are often ejected with a force which the first did not display. A little straining may attend the closing of the operation. For this the operator must be prepared, and immediately withdraw the catheter; lest the bladder, energetically contracting upon it, should cause the point to pierce the sides of the viscus. The instrument is no longer required when straining is excited; for then the contractive function has been resumed, and nature will subsequently perform her office without assistance.
