What is Firm Up?

Firm Up is an all-natural, easy-to-use, food supplement that can help your pup rapidly return to normal intestinal function. A single serving of FirmUp typically resolves loose or liquid stools within 12-24 hours. Just mix Firm Up with your dog’s water or food to get rapid support for your dog’s loose or liquid stools. Suitable for dogs of all ages and sizes.

What are the ingredients?

Firm Up is made from powdered egg solids and dried bovine colostrum. These naturally derived ingredients provide complimentary-food proteins (CFP)to help support your pup’s natural defenses and maintain healthy gut function.

How does Firm Up work?

There are many factors that can cause intestinal dysfunctions, including; travel, change of diet, foreign objects, stress, illness, and new environments.If there is an upset within your pet’s gut, their body will try to remove the unwanted intruder, which can result in loose or runny stools.

Petlab Co.’s Firm Up works with your pup’s digestive system to help restore normal intestinal and gut functions. Offering complimentary-food proteins(CFP) in both active ingredients -powdered egg solids and dried bovine colostrum - to help support your pup’s natural defenses and maintain healthy gut function.

Simply mix one packet of Firm Up with a quarter cup of water and give the entire amount to your dog at the first sign of loose stool. Use additional packs as necessary.

What do I do if Firm Up doesn’t work?

If Firm Up doesn’t work and your pup’s gut issues continue without change, please contact your veterinarian for further support and guidance.

How do I store Firm Up?

Storing Firm Up is simple and easy. We recommend keeping a few boxes of Firm Up (each box contains 3 sachets) in a cool, dry, and easily accessible place - so you can access Firm Up when your pup needs it. Always make sure Firm Up has not surpassed the expiration date before use.

Can Firm Up cause constipation?

There are no ingredients in Firm Up that can cause constipation. Any parts of Firm Up that aren’t used by your dog’s body will pass through just like food.

Can Firm Up be used before any loose stools appear?

Firm Up sachets can be used to prevent liquid or loose stools from happening. If you suspect a stressful situation that may cause gut upset - leading to loose stools - using Firm Up priory can help reduce runny or liquid poop.

What happens if I accidentally give my dog too much Firm Up?

If you do accidentally feed your dog too much FirmUp powder, see a veterinarian as soon as possible. If you’re unsure how much Firm Up to give your dog, please see the Daily Feeding Guide at the top of the page.
