I can't believe the timeliness of this thread.
I'll try to be as brief as possible:
This morning, I let the dogs out as per usual to go to the toilet. No worries, me thinks. They do their business then want to come in because it's breakfast time. Molly goes to the toilet and I put her back inside. Ruby takes a bit longer, is having a "poo walk" as she often does, but is also fine. Lilly (greyhound with a very high prey drive) is standing in the far corner of the garden, transfixed by something in one of the palms. Usually it's a lizard but not this morning. I wasn't to know what would happen a few minutes later. I called Lilly but she ignored me (nothing unusual there). So I returned my attention to Ruby, which by this time she'd finished her thing and so I put her back inside.
I then approach the corner where Lilly stands, and as I get within a few feet, she lunges into the centre of the palm, backs out with something in her mouth, shakes it vigorously a number of times...then I YELL like crazy. She looks, drops the object, and then continues shaking her head. I run over, grab her collar, see a very large green frog (minus one back leg) on the ground, the frog is almost dead but not quite...then I notice there is "stuff" all over Lilly's front half so I march her over to the garden hose. I wash her off, and just when I think everything's okay, I notice the thick ropes of drool escaping her mouth. So I go into toad-mode and begin hosing her mouth out. She bites me a number of times because she *hates* getting her mouth hosed out.
After about five minutes I think it's safe enough to allow her to move away from the hose. She poos, a loose one and very smelly. The drool is still coming so I go back to hosing her mouth out again. Another five minutes go by, and when I stop the second time, she's still drooling. I had NO idea frogs could be toxic but it looks so much like a toad poisoning I know there can't be another explanation.
Just to be sure, I pu her inside and go back to the corner to check on the "victim" and it's definitely a green frog. NOT a toad. I go inside, Lilly's still drooling and looking really sick, so I start calling the after hours number - phone is out of range. It's 45 mins to opening time at the clinic, so I keep ringing, keep observing Lilly, and try really hard not to panic. I do the usual checks, gums are still pink (good), breathing is very fast and shallow (not good), drool still being formed in copious amounts, no tremors, no loss of consciousness...
I can't get through to the after hours number, so I think I'll just have to shower (I'd just gotten out of bed!) and get her to the clinic. But before I can, she vomits, three times. I clean it up, still observing her and she's still drooling. She's really flat...and looks really miserable. I have a really quick shower, then by the time I get out the clinic should be open, so I call the number. I eventually speak to a vet nurse I know well and she knows Lilly... she tells me she doesn't think frogs are toxic and asks me more than once if I'm sure it wasn't a toad. I reply it was a green frog, without a doubt as I checked it more than once. She tells me to keep an eye on Lilly and if she deteriorates, to get her in pronto, otherwise she's probably going to be fine.
Lilly spent the entire morning on her bed, the drooling stopped not long after I made the call. Of course she slept most of the morning, didn't she? She only got yoghurt for dinner tonight and no breakfast, so she'll be hungry in the morning.
Yes, green frogs can be as toxic as cane toads. I've learnt that today and will be letting my vet know what happened.
Sorry this is so long, but the details are very important. If your dog grabs a frog, please take it as seriously as a cane toad incident.
