In combating with the diseases of animals, the veterinary surgeon has more to contend with than the regular physician, and, in fact, should possess a knowledge and habit of observation even superior to the former; although the responsibility of his calling, in a moral sense, is much inferior to that of the other, as the importance of animal existence, under no circumstances, can be placed in comparison with that of human life: still acuteness of observation alone can direct him to the main cause of suffering in the brute creation, as the animal, though groaning under the most severe pains, cannot by any word of explanation point out to us the seat, the probable cause, or peculiar characteristics of such pain. We see that our dog is ill, he refuses his food, retires gloomily to his house, looks sullen, breathes heavy, is no longer delighted at our call. We cannot question him as to his feelings, or ask him to point out the particular region of his sufferings; we watch his motions, study his actions, and rely for our diagnosis upon general symptoms deduced from close observation.

Besides these external ocular evidences of morbid action, we have, as in the human subject, guides to direct us in forming a just opinion as to the nature of a dog's indisposition.

[The]

state of the

circulation

is the first thing that should command our particular attention.

The pulse of dogs in health varies from

one hundred to one hundred and twenty strokes per minute,

according to the size and peculiar temperament of the animal, being more frequent in the small breeds.

The standard of the setter, pointer, hound, &c., may be stated at one hundred and five.
