How much Metamucil for a small dog with chronic constipation?

Updated on September 23rd, 2025

Pet's info: Dog | Chihuahua | Male | neutered | 10 years and 6 months old | 9.6 lbs

I have a 9.6 lb Chihuahua with chronic constipation from having to take basic and 2 different seizure medications... What is proper dosing for metamucil ? My dogs vet says try wet food and give canned pumpkin have tried both with unsuccessful results and want a better aide for dog. Dog also has difficulty pushing stool d/t bad back (very poor muscle strength in back legs).

Hello, sorry to hear about Prince. The dose is 2 tablespoonfuls per day per dog which can be given in a single dose or divided into 2-3 fractions per day. However, metamucil will cause bulkier stools and should be given with an easily digestible diet such as Hill i/D or royal cannin GI low fat. I recommend consulting with your veterinarian prior to starting the metamucil to ensure Prince is a good candidate for it. Hope this helps and best of luck
