Antioxidant Power: Why Blackberries Are a Superfood

Blackberries are one of the most antioxidant-rich foods available, which can benefit your dog in several ways:

Anthocyanins

The deep purple color of blackberries comes from anthocyanins - powerful antioxidants that have been studied for their health benefits:

  • May help reduce inflammation throughout the body
  • Support brain health and cognitive function
  • May help protect against certain types of cancer
  • Support cardiovascular health

Benefits for Aging Dogs

The antioxidants in blackberries may be particularly beneficial for senior dogs:

  • Help fight oxidative stress associated with aging
  • May support cognitive function and reduce "doggy dementia"
  • Support joint health through anti-inflammatory properties
  • Help maintain overall vitality

Superfood Status

Blackberries have one of the highest ORAC (Oxygen Radical Absorbance Capacity) scores of any food, measuring their antioxidant power. While dogs produce some of their own vitamin C, the additional antioxidants from blackberries can provide extra health support, especially for older dogs.

How to Serve Blackberries to Dogs

Fresh Blackberries

Fresh blackberries are the simplest option:

  • Wash thoroughly to remove dirt and pesticides
  • Feed whole to larger dogs, or cut in half for small dogs
  • Can be used as training treats
  • Great for hiding in puzzle toys

Frozen Blackberries

Frozen blackberries make excellent summer treats:

  • Choose plain frozen berries without added sugar
  • Serve directly from freezer as a cool treat
  • Can be slightly thawed for easier eating
  • Great for stuffing in Kong toys and freezing

Mixed Into Food

Add blackberries as a nutritional boost to regular meals:

  • Mash a few berries and mix into dog food
  • Add to homemade dog treat recipes
  • Blend into a smoothie with other dog-safe fruits

DIY Frozen Treat Recipe

Blend blackberries with plain yogurt (no xylitol) and a bit of water. Pour into ice cube trays or a Kong toy and freeze. This makes a refreshing, healthy treat that keeps dogs busy and cool!

Portion Guidelines by Dog Size

While blackberries are healthy, moderation is still important. Too many can cause digestive upset due to the fiber content.

Dog SizeWeightBlackberry PortionFrequency

Medium20-50 lbs6-8 berriesDaily OK
LargeOver 50 lbs8-10 berriesDaily OK

Precautions and Considerations

Natural Xylitol Content

You may have heard concerns about xylitol in blackberries. While blackberries do contain trace amounts of naturally occurring xylitol, the levels are extremely low - about 0.37g per cup. This is far too little to cause any toxic effects. A dog would need to eat an impossible amount of blackberries for this to be a concern.

Digestive Considerations

  • High fiber content can cause loose stools if too many are eaten
  • Start with 1-2 berries to see how your dog tolerates them
  • Seeds may appear in stool - this is normal

Wild Blackberries

Foraging Safely

Wild blackberries are safe, but take precautions: avoid areas that may have been sprayed with pesticides or herbicides, watch out for thorns that can injure your dog's mouth, and don't let your dog eat berries from bushes near roads where pollutants may have settled.

Other Safe Berries for Dogs

If your dog enjoys blackberries, they may also like these safe berry options:

  • Blueberries: Another antioxidant-rich superfood
  • Strawberries: High in vitamin C and fiber
  • Raspberries: Low sugar, good for weight management
  • Cranberries: May support urinary tract health

Toxic Berries to Avoid

  • * Grapes and raisins (highly toxic)
  • * Cherries (pits contain cyanide)
  • * Holly berries
  • * Juniper berries
  • * Mistletoe berries
