Doggy Dailies Probiotic Chews jar for dog gut health
on August 23, 2026

Should I Give My Dog Probiotics or Multivitamins?

Short answer: you likely don't have to choose — probiotics and multivitamins support different parts of your dog's health, and many dogs benefit from both. Probiotics focus specifically on gut and digestive health, while a multivitamin fills broader nutritional gaps across immunity, coat, joints and energy. Doggy Dailies carries a dedicated Probiotic Chews and Multivitamin Chews option for each, so you can pick exactly what your dog needs. Below, we break down exactly what each does, whether your dog needs one or both, and how to build a simple daily routine around them.

What's the Difference Between Probiotics and Multivitamins?

It helps to think of them as doing two different jobs. A probiotic is a targeted supplement — live beneficial bacteria specifically for gut and digestive balance (see our full guide to dog probiotics for more). A multivitamin is broader — a blend of multiple vitamins and minerals covering general wellness across several body systems at once (our guide to daily vitamins breaks this down further).

What Do Probiotics Actually Do?

Probiotics work specifically on your dog's gut microbiome — the balance of bacteria that affects digestion, stool quality, and even parts of immune function. They're particularly useful for:

  • Occasional loose stools or digestive upset
  • Dogs recovering from a course of antibiotics
  • Sensitive stomachs after diet changes or new treats
  • General digestive consistency and comfort

Our Probiotic Chews deliver a concentrated, multi-strain probiotic blend specifically for this purpose — a much higher, more targeted dose than the smaller probiotic amount found in a typical multivitamin.

What Does a Multivitamin Actually Do?

A multivitamin covers ground a probiotic doesn't touch — vitamins and minerals supporting immune function, coat and skin condition, joint comfort, and general energy levels. Our 10-in-1 Multivitamin Chews include:

  • Glucosamine & Chondroitin for joint support
  • Krill Oil & Flaxseed for skin and coat condition
  • Vitamins A, C, D3, E & the full B-complex for immune and energy support
  • Manganese, Zinc & Selenium as supporting trace minerals

Interestingly — our Multivitamin Chews already include a baseline probiotic blend too, since gut health underpins so much of general wellness. But it's a smaller amount than a dedicated probiotic product, which is why dogs with specific digestive needs usually do better on a targeted probiotic alongside it, not instead of it.

Can I Give My Dog Both?

Yes — they target different systems, so there's no meaningful overlap to worry about. Many dogs do well on a daily multivitamin for general wellness, with a dedicated probiotic added during periods of digestive sensitivity, after antibiotics, or simply as ongoing extra gut support. The one thing worth checking: if you're using multiple supplements, glance at the labels to avoid unnecessarily doubling up on the same vitamin at high levels. Because Doggy Dailies makes both, you can easily build a combined routine using products designed to work well together, without mixing and matching between brands.

Which Does My Dog Actually Need?

  • Choose a probiotic if your dog has ongoing digestive issues, is recovering from antibiotics, or has a sensitive stomach
  • Choose a multivitamin if you want broad daily wellness support — coat, joints, immunity, energy — in one chew
  • Choose both if you want comprehensive daily support and your dog has any history of digestive sensitivity

When in doubt, a quick word with your vet about your dog's specific history and diet is the most reliable way to decide.

Building a Simple Daily Supplement Routine

  1. Give both at the same time each day, ideally alongside a meal, so it becomes an automatic part of the routine
  2. Follow the usage chart for your dog's weight on each product — don't guess the amount
  3. Be consistent — both probiotics and multivitamins work cumulatively over weeks, not from a single dose
  4. Watch for changes in digestion, coat condition, and energy over the following month

What If My Dog Won't Take Supplements?

If your dog is fussy, a soft daily chew (rather than a pill or powder) is usually the easiest fix — most dogs take a flavoured chew as readily as a treat. If your dog is still hesitant, try crumbling the chew into their regular food for the first few days until they're used to the taste.

Potential Side Effects to Watch For

Both probiotics and multivitamins are generally well tolerated, but as with any new addition to your dog's routine, it's worth watching for:

  • Mild digestive upset in the first few days as their gut adjusts
  • Reduced appetite
  • Any signs of an allergic reaction

If you notice any of the above, stop use and speak to your vet.

FAQ

Can I give my dog a probiotic and a multivitamin on the same day?
Yes — they target different systems, so there's no meaningful overlap. Just check labels if using multiple products to avoid doubling up on the same vitamin unnecessarily.

Do multivitamins already contain probiotics?
Some do, ours included — but usually at a smaller, baseline level compared to a dedicated probiotic product's concentrated dose.

How long before I see results from probiotics or a multivitamin?
Most dogs show noticeable changes in digestion, coat, or energy within four to six weeks of consistent daily use.

Is a multivitamin necessary if my dog eats a balanced diet?
Most dogs on a complete, balanced diet get their core nutrients from food — but multivitamins can still help fill gaps for seniors, fussy eaters, or dogs on home-cooked diets.

Can puppies have probiotics and multivitamins?
Many products are suitable for puppies from a certain age — always check the specific product's guidance and confirm with your vet first.
