How much d-mannose powder to give to a dog / cat?

As an approximate guideline, a minimum dose of 0.5g of powder is sprinkled on food or mixed with drinking water. Increase dosage based on weight. For every 4kg, increase the dose by 0.5g. For example, a large dog of 16kg would need the maximum dose of 2g of powder. In contrast, a small cat weighing 4kg would need less at around 0.5g.

Is D-Mannose safe for dogs / cats?

Yes, D-Mannose is a natural supplement found naturally in some fruits and vegetables in small quantities. D-Mannose is similar to sugar but not metabolised, meaning there is no risk of increasing sugar intake for cats or dogs. Some breeds of dogs and cats can experience looser bowel movements on rare occasions. If this occurs, reduce the dose or stop using the product for a couple of days. Loose bowel movements tend to occur for cats or dogs sensitive to dietary changes. If you have any concerns, always speak to a veterinary professional.

Waterfall D-Mannose Pet - Treatment and Prevention. For urgent support, a small to heaped teaspoonful (approx. 1-3g) every 2-3 hours with water or sprinkled over food. Please consider weight - a smaller pet may need only a quarter to half a teaspoon. Continue during the night until problems resolve, and then reduce slowly. For prevention, use a little daily.

How to use D-Mannose for Dogs

The dose for your dog will depend on their size. For a medium size dog (11-25kg) one dose will be approximately 1-3gms of powder. For little animals reduce the dose accordingly (for example, if you have a dog which is around half the size of a medium dog, reduce the dose by half).

How to use D-Mannose for Cats

The dose for your cat will depend on their size. For a medium-sized adult cat (6-10kg), 0.5gm to 1gm of powder should suffice. For smaller animals reduce the dose accordingly (for example, if you have a kitten which is around half the size of an average adult cat, reduce the dose by half)

How to use D-Mannose for Guinea Pigs /Rabbits

For an average sized, adult Guinea pig or rabbit one dose will be about a quarter of a teaspoon powder. For smaller animals reduce the dose accordingly (for example, if you have a dwarf rabbit which is around half the size of an average rabbit, reduce the dose by half).

How to use D-Mannose for Horses

For an average sized, adult horse (14-16 hands) one dose will be approx. 5gms of powder. For smaller animals reduce the dose accordingly (for example, if you have a foal that it is approximately half the size of an adult horse, give them half the dose)

Other Pets

 Waterfall D-Mannose Pet can be used for other household pets not listed above. Dosage roughly based on 1g per 10kg of the overall weight of the animal.

I have used the D-Mannose Pet for Cats & Dogs and have found it an amazing product. It has really assisted in managing urinary issues in both my dog and cat. In addition to acute issues, maintaining a remedial dose of twice daily, is really supportive. I totally recommend!

Since using this product my cat has not had a uti which is just amazing!

My spaniel had numerous bouts of cystitis, treated with antibiotics, but the cystitis kept recurring. Did some research and found D-Mannose for pets. I give her a small amount each day and I'm really pleased to say that she hasn't had cystitis again. I am very grateful for this product as it has saved my spaniel from a great deal of discomfort and myself a great deal of worry. Thank you once again
