Be careful with your pups and frogs! Not sure of there's a specific type that does this but my family's Yorkie used to catch them when they came out in the evening. When frogs get scared they let off some liquid like sweat that is poisonous to dogs. She always threw up after having them in her mouth, she's learned her lesson and we try to make sure she doesn't see them on the porch. Again, don't know if it's a specific type of frogs...
the cane toads release a liquid toxic. They look like the pic 2bullymama posted.
