Bailey’s 2 Biscuits…
- Being a southeastern doggie, there are lots of little creatures outdoors, ALL of the time. Many of them, I need to stay away from because they are dangerous to doggies like me. Especially little and not-so-little creatures, like froggies and toads — some of them are poisonous to us furry ones. I recently came just about face-to-face with a Bufo Toad — once one was right outside our front door, and another time in my backyard.
Luckily, my mommy is teaching me to stay away from ALL froggies, since there is no way for me to tell which ones can hurt me. I hope this article teaches you and your human know what to look for, if you happen to spot one of these dangerous creatures. Click here for pictures of frogs and toads.

Cane Toad (Rhinella marina), also known as the “Bufo” Toad or Marine Toad
Cane Toads are native to South and Central America and have become established in central and southern Florida. Toads live on the ground and have stout bodies and dry, warty skin. The poison glands on the shoulders of Cane Toads produce toxins that can kill pets or make them very ill. Native Southern Toads and Oak Toads also have these glands, but their toxins are much less potent and are harmless to pets. Adult toads can be identified using the tips in the bulleted lists below—remember that body color can vary a lot. Native Southern Toads and invasive Cane Toads both lay long strings of eggs, and it is nearly impossible to tell their eggs and young apart. Cane Toads should be humanely euthanized by applying 20% benzocaine gel to the toad’s belly and then freezing the toad.
