Let the dog be placed upon its side, and by means of a handkerchief the penis be drawn. A catheter of proportionate size must be selected. Metallic tubes will not do; but the gum elastic are to be employed. Before one of these is introduced, the wire must be taken out, and the outer surface moistened with olive oil.

The human catheters answer admirably for small dogs; but these are not made long enough to be of service to animals of the larger kinds. For a dog of middle height, an instrument twice the length of those employed on man ought to be at hand; and for a huge Newfoundland, one thrice as long will be useful. The shorter catheters may be of the sizes sold as Nos. 1, 2, and 3; the middle length, 4 and 5; the longest, Nos. 6, 7, and 8.
