Hi Bennett,
Good thinking. A dog that I know ate a heap of walnut cases last autumn (she loves the taste and hunts them down!) and had to be dosed with activated charcoal. Dogs go for some interesting herbs at times. Good to be aware..
For the Solanaceae family toxins:
Barceloux D. G. (2009). Potatoes, tomatoes, and solanine toxicity (Solanum tuberosum L., Solanum lycopersicum L.). Disease-a-month : DM, 55(6), 391–402. https://doi.org/10.1016/j.disamonth.2009.03.009 (Open access link)
I found this a while ago, while researching for my book. It is just a summary but you may find some info in there that leads to interesting research for you.
