Gut Friendly Toppers

Toppers & Treats

LOGIN

A healthy gut is fundamental to your dog’s overall wellbeing. With over 70% of the immune system located in the gut, a well-functioning digestive system is key to preventing a wide range of health issues from uncomfortable tummy troubles to chronic conditions. Adding gut friendly toppers to your dog’s regular meals is a simple way to help soothe inflammation, support beneficial bacteria, aid digestion, and strengthen the gut lining.

Psyllium Husk

Benefits: Due to its water-holding properties, fiber-rich psyllium can help with both diarrhea (by absorbing extra water in loose stools) and constipation (by adding moisture to hard stools). Psyllium husk works as a prebiotic that boosts production of fatty acids in the gut, improving not just stool quality but your dog’s overall gut health as well.

Serving Size: ½ tsp per meal regardless of size of dog.

Frequency: Safe to feed daily until symptoms resolve.

How to Serve: Psyllium husk powder can be mixed into wet food.

Green Bananas

Benefits: Green bananas are unripe yellow bananas. Green bananas are a good source of pectin, a type of dietary fiber. They reduce inflammation and also boost the production of a fatty acid which provides up to 70% of the energy needed by colon cells.

Serving Size:

  • Small dogs (< 20 lbs): ⅛ green banana
  • Medium to large dogs (21-90 lbs): ¼ green banana
  • Giant dogs (> 91 lbs): ½ green banana

Frequency: Safe to feed daily. We recommend rotating toppers for variety.

How to Serve: Remove banana peel and chop into smaller pieces

Important: A medium-sized banana contains 14g of natural sugar, which is over 3 teaspoons of sugar, when it is fully ripe. Choose underripe bananas when feeding to your dog to avoid the high sugar content.

Low Fat Ground Turkey

Benefits: 99% fat-free turkey is easy on the digestive tract and can be soothing for dogs with sensitive stomachs. It’s also high in vitamin B6, which helps control inflammation in the body.

Serving Size: No more than 10% of your dog’s daily meal if being fed as a topper.

Frequency: Safe to feed daily. We recommend rotating toppers for variety.

How to Serve: Feed gently cooked to dogs with sensitive stomachs. To gently cook, simmer the ground turkey in a pan over low-medium heat until it starts to brown.

Important: Feeding raw meat increases the risk of bacterial and parasitic infections.

Sauerkraut

Benefits: Fermented vegetables like sauerkraut provides dogs with beneficial probiotics. Probiotics help maintain and improve gut health while preventing digestive issues like constipation, bloating, and gas. The “good” bacteria from sauerkraut form protective colonies in the digestive system that can help prevent various gastrointestinal diseases and restore balance for a healthy gut flora.

Serving Size: ¼ tsp per 10 lbs of body weight.

Frequency: Limit to 2-3 times per week.

How to Serve:

  • Sauerkraut and other fermented vegetables can either be store-bought or homemade.
  • Many dogs don’t like the tart taste, so it’s best to feed mixed in with food.

Important: Make sure any fermented vegetables you serve your dog are onion-free. Onions are toxic to dogs.

Marshmallow Root

Benefits: Marshmallow root is a beneficial herb for coating and soothing inflamed GI tracts, which helps provide relief from irritation. This herb is especially beneficial for dogs with acid reflux or ulcers as it forms a protective layer on the lining of the stomach and intestines.

Serving Size: 1–2 tsp of cooled tea per 10–20 lbs of body weight, divided into 2–3 servings throughout the day.

Frequency: Safe to feed daily. We recommend rotating toppers for variety.

How to Serve: Infuse in water to make marshmallow root tea:

  1. Bring filtered water to a boil.
  2. Fill one cup of freshly boiled water.
  3. Add 10 grams (about 2 tsps) of dried marshmallow root into a tea strainer.
  4. Place the tea strainer in the cup.
  5. Cover the cup with a lid and infuse for 5-10 minutes.
  6. Remove the tea strainer with the marshmallow root from the cup.
  7. Let tea cool before mixing it into your dog’s food.

Important: If giving your dog medications, give marshmallow root at least one hour away from the medication. This removes the risk of the marshmallow root affecting the absorption of the drugs.

Dandelion Greens

Benefits: Dandelion greens are high in prebiotic fiber, which helps support your dog’s gut microbiome. Another one of its key benefits is its natural diuretic effect that helps increase urine production and boost digestion.

Serving Size:

  • Dried dandelion: ¼ tsp for every 10 lbs of body weight.
  • Fresh dandelion: ½ tsp for every 10 lbs of body weight.

Frequency: Safe to feed daily. We recommend rotating toppers for variety.

How to Serve:

  • Thoroughly washed dandelion greens can be fed raw or sautéd.
  • Feed as a topper or add into your dog’s nutritionally complete homemade meal.

Plain Kefir

Benefits: Recent veterinary research shows that dogs given kefir, a fermented milk drink, developed healthier gut microbiomes, suggesting it can be used as a probiotic supplement to enhance your dog’s overall wellbeing. Kefir is often referred to as the “Elixir of Life” and can be especially helpful for dogs recovering from antibiotic treatment or those suffering from allergies and digestive issues.

Serving Size: 1 tbsp per 10 lbs of body weight.

Frequency: Safe to feed daily. We recommend rotating toppers for variety.

How to Serve: Mix in with your dog’s food or serve on the side as a healthy treat.

Pumpkin

Benefits: Pumpkin’s high fiber content helps regulate your dog’s digestive system and supports gut health. It is often recommended by veterinarians as a safe, natural remedy to help minor stomach issues like diarrhea or constipation.

Serving Size: 1 tsp per 10 lbs of body weight.

Frequency: Safe to feed daily. We recommend rotating toppers for variety.

How to Serve: Look for 100% pumpkin puree (with no added sugars or spices) if shopping for canned pumpkin at the store. Mix in with food.

Fennel Seed

Benefits: Fennel seed is known to soothe the digestive system by helping to reduce gas, bloating, and indigestion. When fennel seed extract was given to mice, research found that it helped protect and strengthen the gut lining.

Serving Size: ¼-½ cup per 20 lbs of body weight, divided between 3 times daily.

Frequency: Safe to feed daily. We recommend rotating toppers for variety.

How to Serve: Infuse in water to make fennel tea:

  1. Bring filtered water to a boil.
  2. Fill ¾ cup of freshly boiled water.
  3. Add ¼-½ tsp of fennel seeds into a tea strainer.
  4. Place the tea strainer in the cup.
  5. Cover the cup with a lid and infuse for 5-10 minutes.
  6. Remove the tea strainer with the fennel seeds from the cup.
  7. Let tea cool before mixing it into your dog’s food.

Ginger Root

Benefits: Known for its nausea-relieving properties, ginger is an excellent natural remedy to ease your dog’s upset stomach. A small amount of ginger can aid in digestion by breaking down food, and calming an upset stomach by stimulating saliva, bile, and gastric juice production.

Serving Size:

  • Small dog (< 20 lbs): ⅛ tsp freshly ground ginger
  • Medium dog (21-50 lbs): ¼ tsp freshly ground ginger
  • Large dog (> 51 lbs): ½ tsp freshly ground ginger

Frequency: Safe to feed daily. We recommend rotating toppers for variety.

How to Serve:

  1. Remove the skin of the root with a knife to access the yellow inside.
  2. Finely mince or grate the yellow inside of the root.

Chamomile Tea

Benefits: Chamomile is a gentle, calming herb that supports both the nervous system and the digestive tract. It’s especially helpful for dogs with gut symptoms connected to anxiety, such as gas, nausea, or intermittent diarrhea. It also acts as an antispasmodic, easing muscle tension in the GI tract and reducing inflammation.

Serving Size:

  • Small dog (< 20 lbs): 1-2 tsp of cooled tea
  • Medium to large dog (> 21 lbs): 1-2 tbsp of cooled tea

➝ Start with smaller amounts to assess tolerance.

Frequency: Chamomile is generally safe, but avoid longterm daily use unless directed.

How to Serve:

  1. Use dried organic chamomile flowers or a plain, unsweetened chamomile tea bag.
  2. Steep 1 tsp of flowers (or 1 tea bag) in 1 cup hot water for 5–10 minutes.
  3. Let cool completely and mix into your dog’s food or serve separately.

Important: Do not use if your dog has ragweed allergies, as it may cross-react.

Beets

Benefits: Beets support liver detoxification, bile production, and blood health. They’re rich in antioxidants, folate, and fiber, making them a helpful addition for dogs with constipation, sluggish digestion, or toxin burden identified through a hair tissue mineral analysis (HTMA).

Serving Size:

  • Small dog (< 20 lbs): 1-2 tsp of cooked beet
  • Medium to large dog (> 21 lbs): 1-2 tbsp of cooked beet

Frequency: Limit to 2–3x weekly unless advised otherwise.

How to Serve:

  1. Peel and steam or roast until soft, then finely dice or mash.
  2. Raw beets can be grated, but cooked is gentler on sensitive stomachs.
  3. Mix into food as a colorful, nutrient-dense topper.

Important:

  • Beets may temporarily tint your dog’s urine or stool pink.
  • Start slow due to their high oxalate content.

Broccoli Sprouts

Benefits: Broccoli sprouts are tiny but powerful. They’re packed with sulforaphane, a compound that activates detoxification enzymes and supports gut-liver axis healing. They also help protect the gut lining and reduce inflammation. Ideal for pets with chronic health issues, heavy metal exposure, or low detox capacity shown on a hair tissue mineral analysis (HTMA).

Serving Size:

  • Small dog (< 20 lbs): ¼-½ tsp
  • Medium to large dog (> 21 lbs): ½-1 tsp

Frequency: Limit to a few times per week. Avoid overuse, especially in dogs with thyroid conditions, due to goitrogenic in high amounts.

How to Serve:

  • Purchase fresh, organic broccoli sprouts or grow your own at home.
  • Chop finely and mix into food raw for maximum sulforaphane benefits.
  • You can lightly steam if your dog is extremely sensitive, but raw is ideal.

Important: Introduce slowly to avoid gas or bloating.

Bone Broth

Benefits: Bone broth is rich in glycine, collagen, and minerals that help repair and seal the gut lining, support joint and skin health, and replenish electrolytes. It’s especially helpful during GI flares, post-surgery recovery, or after antibiotic use.

Serving Size:

  • Small dog (< 20 lbs): 1-2 tbsp
  • Medium dog (21-50 lbs): ¼-½ cup
  • Large dog (> 51 lbs): ½-1 cup

How to Serve:

  • Use homemade or dog-safe store-bought bone broth with no onions, garlic, or added salt.
  • Simmer meaty bones with apple cider vinegar for 12–24 hours, then strain.
  • Cool completely before serving. Can also freeze into cubes for daily use.

Important: If your dog is histamine-sensitive or in a flare, introduce slowly or use meat broth (shorter cooked) instead of long-cooked bone broth.

Frequently Asked Questions

Q: How much of these toppers can I add to my dog’s bowl?

These toppers can be used to boost your dog’s current food using the 90/10 rule, where you feed 90% of your dog’s current food and 10% of the above toppers. Adding only 10% of the above toppers will not “unbalance” your dog’s current food. If you’d like to add more than 10% fresh food toppers, you need to ensure the fresh food you’re adding is a nutritionally complete meal.

Q: How do I calculate how much kibble to replace?

(Daily amount of kibble fed) x (% of fresh food you’re adding)

3 cups of kibble daily x 10% fresh food toppers

= 0.3 cups of kibble to remove
