That's what my vet told me.
Don't mix it with the food, otherwise they may not eat the food anymore.
I remember spending $5k one weekend after I fed my dogs macadamia nuts.
I got up the next morning and they were both lying in their beds still, just a low whimper.
I had a look at em, picked one up and she just flopped back onto her stomach.
Straight down to the emergency vets, lucky only 10mins away.
They gave them, drips, scans, charcoal down the gut to absorb the toxins from the nuts.
Both survived, they were only around 5-6 years old tho. what a fool I felt like.
Not to mention the $3k I spent when they first discovered toads.
Gotta have pet insurance, I don't care what anyone says.
