female dog, therefore, should always be allowed to breed. Breeding is a necessary process; and the female prevented from it is sure to be affected with disease sooner or later; enormous collections and indurations will form, that will inevitably terminate in scirrhus or ulceration.
troublesome process often occurs when the female is not permitted to have young ones; namely, the accumulation of milk in the teats, especially if at any previous time, however distant, she may have had puppies once. The foundation is laid for many unpleasant and unmanageable complaints. If she is suffered to bring up one litter after another, she will have better health than those that are debarred from intercourse with the male.
The temporary union which takes placed between the male and female at the period at which they are brought together is a very singular one. The
corpora cavernosa
of the male and the
clitoris
of the female being suddenly distended with blood, it is impossible to withdraw either of them until the turgescence of the parts has entirely ceased.
