Most healthy adult dogs tolerate bovine colostrum at label amounts, and loose stool in the first week is the usual complaint. The real risk sits with particular dogs: those with a dairy or beef allergy, lactose trouble, several food allergies, kidney disease, or a very young puppy. Each of those has its own page below.

Who should ask a vet before trying colostrum
Four Leaf Rover Bovine Colostrum is a single ingredient, which makes it simpler than most chews, but that ingredient is concentrated cow's milk protein. Ask your vet before starting if any of these apply:
- Confirmed dairy or beef allergy. Colostrum shares proteins with cow's milk and, to some degree, beef. A dog with a true food allergy to either may react with itch, ear flare or stomach upset.
- A food-elimination trial in progress. Any animal-protein supplement can spoil the trial and leave you unsure what caused a reaction; the dog food allergy guide explains how these trials work.
- Kidney disease. Dogs with chronic kidney disease are often on protein- and phosphorus-managed diets, so any new protein source should be checked against that plan.
- Pancreatitis or a strict low-fat diet, or any other chronic illness being managed by your vet.
- Prescription medication, especially immune-modulating drugs.
- Puppies under the label age, and pregnant, nursing or breeding dogs. The Four Leaf Rover label states that safe use in pregnant animals or animals intended for breeding has not been proven.
- Older dogs with any of the above, or new weight loss or gut signs. What is and is not known is in colostrum for senior dogs.
- Open wounds, skin or ear infection, or sudden severe itching. These need a diagnosis first. A supplement will not resolve an infection.
How to lower the risk when you do start
- Begin at about half the amount on your jar's chart for the first week. The dosage calculator gives the full amount for your dog's weight.
- Add only one new thing at a time, so you know what caused any change.
- Watch stool, appetite, vomiting and itch for the first one to two weeks.
- Stop and call your vet for vomiting, diarrhea lasting more than a day or two, blood in the stool, hives or facial swelling.
