I think your dog is getting ahold of toads and not frogs. Toads secrete substances to make them distasteful. My dog just discovered toads last week. My husband brought him in from a walk outside and deposited him at my feet with the command "you need to look at him". LOL.

He was foaming at the mouth and shaking his head. I washed his mouth out and he was better directly. But, I live in an area where there is no danger of him getting a potentially lethal toad. They are out there in certain localities. I think he'll leave them alone from here on.

OTOH, my dear old male tabby always forgot over the winter what happens when you bite a toad. As soon as it warmed up each spring, he'd eat one, barf and drool and be sick for awhile and he'd be cool the rest of the year. But, we did the dance once each spring.

I think calliope is right;
the taste of the critter itself is bad enough that the puppy will learn.

I'm afraid if you squirt something objectionable into her mouth, it would teach her to avoid you when she has the problem *rather than to avoid the problem itself*.

Puppies are fun, but thank goodness they grow up before they destroy the universe & run their mommas nuts!

Thanks,I'll research and see if the lethal ones are in Ga.I don't think she is going to learn her lesson from the taste.She has been squirted/sprayed several times with recently being the worst.I see her outside messing with something then she starts shaking her head and I go to get her and see the toad.
Your are right Sylvia,somedays I wonder what I was thinking by keeping a puppy!
