#1 – Peach, Plums, and Persimmons
It is definitely true that the flesh of these fruits can be both healthy and safe for humans and dogs. But the pits or the seeds are very dangerous. Persimmon seeds can cause severe problems to the dog’s small intestine and the digestive system.
Also, plum and peach seeds cause serious issues like blocking your puppy’s digestive tract which may demand surgery. In addition to that, plum and peach pits contain cyanide, a toxic acid that could kill humans and dogs.
