Frequently asked questions
What makes black walnuts toxic to dogs?
Black walnuts contain juglone (5-hydroxy-1,4-naphthoquinone) which affects multiple organ systems and causes neurological effects in dogs.
How do I tell black walnuts from English walnuts?
Black walnuts have a very dark, thick, intensely ridged husk and a much stronger smell. English walnuts are lighter. When in doubt, treat any walnut as potentially dangerous.
