Dear A.M. Costa Rica:
I read with interest your statement that avocados are poisonous to dogs in the A.M. Costa Rica of Sept. 1. This is completely incorrect. I have been an avocado grower in California, and one of the favorite foods around an avocado grove for both dogs and coyotes is fallen avocados. My last dog lived to about 14 1/2 eating avocados. Also, the favorite dog food for show dogs because it gives their coat a beautiful sheen is a food made from avocados called AvoDerm. You should check your facts.
Many birds such as the quetzel also eat wild avocados, and I doubt they are poisonous to parrots either, but not sure.

Editor’s Note: The American Society for the Prevention of Cruelty to Animals lists avocados as being hazardous to dogs. It names the Guatemalan variety, a common one found in U.S. stores, as the most problematic. Other varieties of avocado can have different degrees of toxic potential.
In some dogs and cats, mild stomach upset may occur if the animal eats a significant amount of avocado flesh or peel, it says. Avocado meal used in pet foods would not pose a hazard to dogs and cats, it says.
