Dogs and Palm Nuts

My dog, Sophie, recently ate a palm nut. We have Palms in our yard and their seeds are little nuts that fall off the trees. Sophie chews on them, and the gross-smelling juice comes out and she eats it. We try to keep them away from her, but she managed to eat one when we were not looking. She was throwing up for the next few days, so we took her into the vet and they said nothing was wrong, so we thought it was a stomach bug. When she did not stop throwing up, we took her in again and the vet gave her x-rays and found that a palm nut was lodged in her intestines, so she had to have surgery. Luckily, we could spay her at the same time, so she did not have to have another surgery, but the cost was like buying her all over again. So palm nuts are not poisonous, but very dangerous, especially when eaten.
