Goat milk is a nutrient-dense food with a unique composition that supports various health benefits. It is rich in essential proteins, fats, vitamins, minerals, and bioactive peptides that enhance its nutritional value. Key properties include easy digestibility, potential hypoallergenic benefits, and bioavailability of nutrients.
-
Supports immune function with bioactive peptides aiding in immune defense.
-
Promotes gut health fostering a balanced gut microbiome
-
Supports bone health with highly bioavailable minerals
-
Reduces oxidative stress with antioxidants that neutralize free radicals, lowering chronic disease risks
-
Modulates immune responses with immunomodulatory compounds that enhance pathogen defense.
-
Supports metabolic functions through its rich mineral content and bioactive components.

Bovine colostrum, the first milk produced after a calf is born, is naturally rich in lactoferrin, lysozyme, lactoperoxidase, growth factors, and immunoglobulins (antibodies IgG, IgM and IgA). These bioactive compounds are well-researched and support healthy immune function, immune balance, healthy skin, digestive health, gut microbiome diversity and stability, and stool quality.
- Supports immune function in pets with seasonal allergy
- Supports digestive concerns from multiple causes
- Improves stool quality in puppies with environmental stressors or diet change
- Supports healthy and robust immune response to vaccination
The colostrum in Respond + comes from grass-fed USA cattle.
DHA sourced from microalgae Schizochytrium sp. is a highly bioavailable, plant-based omega-3 fatty acid that supports overall health in dogs and cats. It promotes brain development, eye health, and a shiny coat while reducing inflammation and supporting cardiovascular, immune, and digestive health. As a hypoallergenic alternative to fish-based DHA, it provides a safe and effective option for pets of all ages. Algae is particularly environmentally friendly because it grows rapidly, requires minimal resources, and reduces pressure on marine ecosystems by offering a sustainable alternative to fish-derived products.
-
Supports cognitive development in puppies and kittens
-
Improves skin condition and enhances coat shine
-
Supports cardiovascular health and circulation.
-
Strengthens immune system function.
-
Protects cognitive function in senior pets.
-
Offers a hypoallergenic, environmentally friendly plant-based DHA source
-
Supports gut health and digestion

Larch Arabinogalactan is a soluble fiber that not only supports digestive health, but also healthy immune system function. This natural substance sourced from the bark of the larch tree (Larix occidentalis), has been shown in studies to enhance natural killer cells and macrophages, part of the body’s natural defenses. Studies have also shown it to improve levels of beneficial bacteria and reduce levels of harmful bacteria in dogs.
Saccharomyces boulardii is a gut-friendly probiotic yeast, not bacteria. Yeast-based probiotics are particularly unique because they're not harmed by the drugs and chemicals that can damage other probiotics and bacteria. Unlike bacterial probiotics, S. boulardii isn’t affected by antibiotics, so it can be given at the same time as antibiotic treatment. This can be helpful to reduce digestive side effects that antibiotics often cause. Studies have shown that when S. boulardii is given along with an antibiotic, dogs are much less likely to develop digestive upset from the medication.
- Improves stool frequency
- Is safe and effective for dogs and can prevent and reduce diarrhea from multiple causes
- Reduces diarrhea caused by antibiotics
- Supports healthy immune function
- Supports healthy gut barrier function
- Promotes healthy skin
- Helps to regenerate gut microbe populations after dysbiosis (imbalance of gut bacteria)
- Supports gut microbiome diversity
- Supports gut function by feeding beneficial bacteria
Nutritional yeast is a deactivated form of Saccharomyces cerevisiae that is widely used as a functional food due to its bold natural cheese flavor and health-supporting benefits. Nutritional yeast is an excellent source of beta-glucans and exhibits many of the same immune-supportive benefits as mushrooms including protective benefits against bacterial and viral infections, immunomodulation and anti-allergic effects. Nutritional yeast has been shown in research to support healthy immune system function, and act as prebiotics to support gut health, gut microbiota diversity and stability.

Reviews
Tried this for my picky IBD cat that has been struggling. This actually was my last ditch effort in trying to help her to feel better. Within 3 days of using this probiotic I started to notice changes in her. Increase appetite, energy, more vocal and coming around with our family. After about a week of daily use, she is back to her normal self. I am SO impressed by this product. My cat is extremely picky, but likes the flavor of this.
