How to Serve Blackberries Safely
Rinse fresh berries, remove spoiled or moldy fruit, and offer them plain. Mash or cut berries for a tiny dog that gulps food. Skip jam, pie, cobbler, yogurt toppings, sweetened frozen blends, and any product with xylitol.
What to Watch For
The usual problem is digestive upset: gas, vomiting, or diarrhea after too many berries. Repeated vomiting, weakness, loss of coordination, collapse, or blood in vomit or stool needs prompt veterinary advice.
When to Call a Vet
