Your Frenchie’s Gut Just Needs a Little Time to Adapt

A short, friendly guide to your first week on PawGuard: what to expect, why a soft stool or a bit of gas at the start is normal, and the two simple things that make it gentle.

If your Frenchie has had a slightly softer stool, a bit more gas, or even brought their dinner back up in the first few days on PawGuard, take a breath. Don’t stop. This is almost always the gut adjusting, and it usually means the chews are doing exactly what they’re meant to.

I hear this from new owners every week, so let me walk you through what’s happening, why it’s normal, and the two small things that make the first week easy.

A soft stool or a little gas early on isn’t the product failing. It’s the gut rebalancing, and it passes.

You’re Not Alone, and This Is Expected

If you’ve noticed any of these in the first few days, you’re in very good company. It’s one of the most common things new Frenchie owners write to us about, and it’s almost always the same harmless adjustment:

  • A softer or looser stool
  • A little more gas than usual
  • A single, one-off vomit
  • A slightly smaller appetite for a day or two

French Bulldogs have famously sensitive stomachs, so they tend to show this adjustment more visibly than most breeds. For nearly all of them, it settles within a week or two, and below I’ll show you exactly how to make it pass faster and more comfortably.

Why This Happens, in Three Simple Reasons

The good bacteria are moving in. When you add probiotics to a gut that’s been a little out of balance, and in Frenchies it often is, the new friendly bacteria compete with and crowd out the bad ones that were already there. That changeover stirs things up for a few days, a bit of gas, a softer stool, while the balance resets. It’s a real, well-documented adjustment, not a reaction, and it usually settles within three to seven days.

There are healthy new fats to get used to. Every chew carries Wild Alaskan Salmon Oil, which is wonderful for skin, coat and joints but brand new to your Frenchie’s system. When the gut meets more good fat than it’s used to, some of it isn’t absorbed yet, so the intestine draws in a little water and the stool comes out soft. For most dogs this isn’t an allergy, just digestion catching up.

A rich chew on an empty tummy hits harder. The chews use a pork liver base, which is also why Frenchies love the taste. Given on an empty stomach, that richness and the salmon oil can occasionally bring on a one-off vomit. This is the easiest one to prevent, which leads straight to the single most important tip on this page.

🍽️
The one rule that prevents most of it: always give the chew with food Tuck the chew into a meal, or give it right after your Frenchie eats. Never on an empty stomach. Food slows everything down, settles the richness and the salmon oil, and makes the whole first week far gentler. If you do nothing else on this page, do this.

Ease Them In: The Gentle First-Week Ladder

Don’t jump to the full dose on day one. Let the gut catch up first. Here’s the exact approach I recommend:

  • Days 1 to 7, start at half. Give half the daily amount, with food, for the first week (see your Frenchie’s size just below). This one step prevents most upset before it starts.
  • All calm? Move up to the full dose. If the first week went smoothly with firm stools and no fuss, step up to the full daily amount from week two onward.
  • A bit of upset? Drop down, then climb back slowly. If you see a soft stool or extra gas, don’t stop. Halve whatever you’re currently giving (for many Frenchies that’s about a quarter of a chew), hold for three to four days, then step back up gradually. A smaller, slower introduction lets the gut settle more gently.
  • There’s no rush. Some sensitive Frenchies need ten to fourteen days to fully settle, and that’s completely fine. Going slow is never wrong.

What’s Normal, and When to Call Your Vet

💚 Normal & expected
  • Mild, short-lived softer stools or gas
  • A single, one-off vomit
  • A slightly smaller appetite for a day or two
  • Everything easing off within one to two weeks
⚠️ Pause & call your vet
  • Vomiting or diarrhea that is severe, repeated, or lasts more than a couple of days
  • Any blood in the stool or vomit
  • Lethargy, refusing food or water, or signs of dehydration

If you see any of these, stop the chews and contact your vet. Persistent tummy upset can dehydrate a small dog, and your vet should always come first.

What the First Week Is Leading To

The owners who ease their Frenchie in gently are the ones who get the good part. Here’s the order it tends to arrive in:

  • Week 1 to 2, the gut wins come first. A calmer stomach, firmer stools, and far less of that room-clearing gas.
  • Week 3 to 4, the slower wins. A softer, shinier coat and steadier, more comfortable joints, because skin and joints rebuild more slowly than the gut.

A few gentle days now is simply the price of all of that. It’s worth it.

You’re Doing the Right Thing

Starting something good for your Frenchie sometimes means a few gentle days while their body catches up. Give the chews with food, take the first week slow, and you’ll very likely be on the other side of this within a week or two, with a happier gut to show for it.

If anything ever worries you, your vet is always the right call. And if you have a question about the chews, just reply to your order email and our team will help.
