Prognosis was doubtful, the owner being informed that the dog was probably sufferin g from chronic liver disease resulting in serious embarra ssment to the vascular syste m , At hi s urgent request treatment was undertaken.

The dog, which had previously refused all food, soon recovered his normal appetite, and appeared to be making fair progress. Within a week the dropsical transudate again began to accumulate.
