Why Colostrum? Because Your Dog Deserves Real, Lasting Relief

Most “solutions” only hide symptoms for a few days…

Colostrum works at the root cause:

- Restores a healthy gut lining

- Reduces inflammation & itching

- Strengthens natural immune defenses

- Helps dogs recover faster from stress, illness, or allergies

When the gut heals → the skin heals → the whole body heals.

RUBOLD Colostrum gives your dog the foundation for a lifetime of health.

Sara and Luna

"I was honestly skeptical, but this stuff really helped my dog. He’s had allergies and occasional tummy issues for a while, and nothing ever seemed to make a big difference. After a couple of weeks, he’s itching way less, his poop is finally normal, and he’s got more energy. I started slow and he handled it great—no stomach problems at all. Plus, he actually likes it, which is rare for him. I’m definitely sticking with it.

Jennifer & Buddy

"I give my (3) dogs colostrum once a day. It helps with allergies, immunity and general health...it's especially good for puppies. Nobody seemed to mind the switch to this powdered colostrum. It dissolves well in wet food or with a little water.

Marcus & Max

"My dog has benefited a lot from this colostrum powder. It helps with digestion, skin, and overall immune support. Easy to mix with food, and I feel confident knowing it’s pure, grass-fed, and made in the USA with no fillers. I’ve noticed less itching and better gut health since using it. Highly recommend for any dog with digestive or allergy issues!"

Your Questions, Answered

Q: How quickly will I see results?

A: Most dog parents notice improvements in gut health, coat condition, and allergy symptoms within 2–4 weeks of consistent use. Every dog is different, so some may respond faster or slower depending on their health history.

Q: Is RUBOLD safe for all breeds?

A: Yes! RUBOLD Colostrum Powder is 100% natural and gentle, making it safe for all breeds and sizes. Always follow the recommended dosing, and consult your veterinarian if your dog has special health concerns.

Q: How often should I use this?

A: For therapeutic support, give 1/4 scoop per 15 lbs of body weight daily. For wellness or maintenance, simply use half the therapeutic amount. Start with half the dose for the first 3 days to support comfortable digestion.

Q: My dog hates anything poured on his food. Will this work?

A: Absolutely. RUBOLD Colostrum Powder is odorless, tasteless, and easy to sprinkle over food. Most dogs eat it without noticing, even picky eaters.

Q: Can I use this if my dog currently has a bad allergy?

A: Yes! Colostrum is designed to support the immune system and reduce inflammation from the inside out. It’s safe to use alongside other allergy management methods, but we recommend consulting your veterinarian for severe cases.

Q: What if it doesn't work for my dog?

A: We understand every dog is unique. While most see results within weeks, some may take longer. Our support team is happy to help troubleshoot dosing or answer questions, and we stand behind our product’s quality and purity.

Q: How is this different from other allergy supplements?

A: Unlike symptom-masking products, RUBOLD works with your dog’s natural biology. It targets gut repair, immune balance, and inflammation control, rather than just covering up symptoms. Plus, it’s pure, human-grade, grass-fed colostrum with no fillers, flavors, or additives.
