Can dogs eat cherries? No! Dogs absolutely should not eat cherries. The fleshy part is not dangerous however the pits, stems, and leaves contain cyanide and is deadly for dogs.
You may be wondering about maraschino cherries because they have the pits removed. The issue, however, is that maraschino cherries are sweetened with a lot of sugar and are not a good treat for dogs.
If your dog happens to get one cherry pit they will not get cyanide poisoning, however the seed could still cause intestinal blockage. So watch for vomiting, decreased appetite, constipation, and decreased fecal production. You may also need to check to see if the seed passes. If your dog eats more than one cherry you should contact your vet and watch for signs of cyanide poisoning which may include dilated pupils, difficulty breathing, and red gums.
