One of our young horses came up with a swollen submandibular gland Nov. 16th, no fever, no nasal discharge, no decrease in appetite and normal energy level. The other gland felt slightly enlarged. I quarantined the horse and began giving hepar sulf. calc. 3x a day. As of today the gland has shrunk slightly. I am wondering if i should continue with the hepar, or change up remedies. From what I have read, if this is strangles it is a very mild case. And if it is not, i am not sure what it is - any advice would be appreciated. Thanks.
