Frequently asked questions

Colostrum is the first milk mammals produce after giving birth, naturally rich in immune-supporting compounds like IgG and lactoferrin. A colostrum supplement for dogs is used to provide daily immune support in dogs aged 12 weeks and older.

ImmunoBlend™ is a daily colostrum supplement for dogs, designed to support a healthy immune system, the gut-immune axis, and seasonal allergy response, as part of a consistent daily routine.

Colostrum supports a dog’s immune system by providing naturally occurring compounds, like IgG and lactoferrin, which help support healthy immune signaling and the intestinal mucosal barrier. ImmunoBlend™ provides daily immune support for dogs with a simple daily scoop.

Yes - daily colostrum supplements for dogs can be a good addition to a daily routine when given consistently and according to label instructions. Colostrum is well-established for supporting a dog’s immune system, and is generally suitable for dogs of all ages from 12+ weeks.

ImmunoBlend™ isn't designed to do everything. It's built with focus: colostrum has a clear immune-support role, and the formula is built around delivering that consistently, every day.

Yes, most puppies can take PetLabCo.® ImmunoBlend™ Colostrum Powder from 12+ weeks old. Many pet parents choose to start proactive immune support from a young age. Always follow the directions for use on the tub and speak to your vet if your puppy has any health concerns or special dietary considerations.

Deciding when to start giving your dog a colostrum supplement is something you should discuss with your veterinarian. PetLabCo.® ImmunoBlend™ Colostrum Powder is suitable for all pups over 12 weeks old.

ImmunoBlend™ is formulated with high-quality bovine colostrum to support a healthy immune system, healthy immune signaling, and gut-associated immune function, including the gut-immune axis. It's also formulated to support immune health alongside seasonal allergy response — all from one active ingredient, in a simple daily scoop.

Both support your dog's immune health, but in different ways. Allergy & Immune Chews are a broader multi-ingredient soft chew formula. ImmunoBlend™ is a colostrum-led powder built around one active ingredient, for owners who want a more focused, ingredient-led approach.

Every dog is different, so results can vary. ImmunoBlend™ is formulated for consistent daily use as part of your dog's ongoing routine, rather than a one-time solution. Many owners build it into their dog's routine long-term, particularly around seasonal changes. As with any colostrum supplement for dogs, individual results may vary. 

Yes, ImmunoBlend™ is formulated for daily use. As with any new supplement, we recommend consulting your veterinarian before starting a new routine.

ImmunoBlend™ is built around US-farmed bovine colostrum for dogs, sourced from American farms. It's a focused two-ingredient formula — no long list to decode — and it's backed by PetLabCo.®, a NASC-certified brand supporting the health and wellbeing of over 5.7 million dogs worldwide.

Our colostrum powder for dogs has been formulated with two ingredients: bovine colostrum and goat’s milk powder (for flavor). We aim to make our pet supplements as inclusive as possible, but because both are dairy-derived, dogs with known dairy or lactose sensitivities should be introduced to the product gradually. It's best to consult your veterinarian to ensure it’s a suitable addition to your dog’s diet.

ImmunoBlend™ is designed to stack with your dog's existing routine, including other PetLabCo.® products like probiotics or joint supplements. If your dog is on prescribed medication, speak with your veterinarian before adding any new supplement to their routine.

If you accidentally give your dog too much colostrum powder, see a vet immediately.
