These fits are due to pressure on the brain by distended bloodvessels, or by effusion of blood, or of serum. They specially seize dogs that are confined or over-fed.

Symptoms

The symptoms of the attack are, that the dog is almost, or wholly insensible, lying motionless, and breathing heavily and noisily. The eye is fixed and suffused with blood; there is no foaming at the mouth. In some cases death is instantaneous; and, of those that are not so, the majority are fetal under any treatment whatever.

Treatment

The medicines most likely to do good are Aconitoim and Belladonna, given in doses of one pilule every half hour alternately, commenc-ing with the former. Opium, in the same way, is indicated when the breathing is loud and heavy, and the insensibility profound.
