I'm pretty positive I know why she's sick. I bought six Coleus and planted them just off the back porch under the trellis Barnaby built. Two of them were destroyed and half-eaten sometime from Thurs-Fri morning. I didn't have any idea they were poisonous to dogs, but they are. I've done some research on the Internet and found a LONG list of plants that are poisonous to dogs, and Coleus is on that list. Lantana is also on that list as one of the most toxic, and we have some of that this year too.
I'm putting together a comprehensive list to post in my sidebar. Look for it soon and print it or save it for reference. I'm shocked at how many common plants are on this list!
I bawled my eyes out last night because I just felt like she is dying. I know it sounds dramatic, but will you say a little prayer for Sammi please?
