Hi, I c ught Oscar eating the fruit of a tree that grows in the back yard. I am not sure whether this good or not I am pretty sure it is some kind if laurel. The berries are dark on the outside and red inside, their is a pip in the middle. He hadn't eaten the pip just the flesh of the berries. I think I have read that these pips can be poisonous to dogs in the at if the pip us crunched it released cyanide!! I have put some photos on tho show you obviously the leaf the berry and the pip if anyone has any ideas please let me know.
