Your Guide to Buying the Best Dog Food for Firm Stools
Ready to buy dog food that will help your pup have firmer stools? Here’s what you need to know.
What Causes Loose Stools
First, let’s look at what can cause loose stools.
Change in Diet
If you’ve recently changed your dog to a new food, and they start to have loose stool, the food may be the issue.
A fast change in diet, especially with ingredients that don’t agree with your dog’s tummy, can cause diarrhea and an upset stomach. While it resolves by itself (usually), there are ways to switch your dog without trouble.
When or if you change your dog’s diet, start slow. Mix the food with their old food for a few days to get them used to it. Then you can switch them over to the new formula.
Low-quality dog foods without enough protein, healthy fats, and essential nutrients can cause havoc on your dog’s digestive system.
This is why a dog food formula that meets AAFCO requirements, and provides plenty of beneficial ingredients, is essential.
Bacterial Infection and Viral Diseases
Even if your dog eats well and is active, they can still pick up an infection or disease. These are usually contagious, and some can be life-threatening.
These diseases include Parvovirus, distemper, salmonella, and inflammatory bowel disease. And that’s to name a few.
If your dog has blood or mucus in their poop, vomits, or has a lack of appetite, get them checked by your vet immediately.
Do you have a dog that likes to play outside or loves stagnant water? Be careful, as parasites lurk outside.
And, if your dog drinks or eats anything that’s contaminated, they’ll swallow these parasites. This can cause all types of issues — including diarrhea.
The most common parasites are roundworms, hookworms, Coccidia, and Giardia. If you suspect your dog may have eaten or drank something they shouldn’t, you can take them to the vet.
They will be able to test for parasites and prescribe medication that rids your dog of them.
Yes, your dog has feelings too. And in extreme cases, these emotions can cause issues like a sensitive stomach or loose stools. This is especially common with toy breeds and working dogs too.
If you’ve had a recent event like moving, taking them to a kennel, or even dealing with grief (like the loss of a loved one), your dog may have acute diarrhea.
What to Look for When Buying Dog Food for Firm Stools
If your dog has diarrhea or loose stools, some ingredients and diets can help firm up their stool. Here’s what to look for.
Most commercial dog foods are great at offering natural ingredients. Real animal proteins, fruits and vegetables, and healthy carbohydrates and fats are essential.
But, some may include additives that don’t add any nutrition to your dog’s food. Try to avoid fillers like by-products, corn, wheat, and soy when possible.
While many dogs can handle these ingredients, dogs with sensitive tummies and loose stool may not process them very well.
Probiotics and Prebiotics
Prebiotics and probiotics introduce healthy bacteria into your dog’s stomach. This aids in better digestion and can keep them regular without causing diarrhea or constipation.
High Fiber Content
High-fiber content helps keep stool firm by soaking up extra fluids in the digestive tract.
And fiber from carbohydrates like brown rice, pumpkin, and sweet potatoes helps break down food during digestion. This helps firm up the stool and keeps your dog regular.
Some dogs with sensitive stomachs need to avoid certain ingredients that can cause intolerance. This may include grains. If your pup can’t handle grains well or is allergic to them, you may want to switch them to a grain-free diet.
Be sure to find one with healthy carbohydrates, like peas, pumpkin, and sweet potatoes. And, a grain-free formula with prebiotics, probiotics, and healthy fats is better than one without.
Did you know that a high-fat diet can cause loose stools? In some dogs, many oils and fats in food can irritate the stomach.
This is because they can’t absorb all the fat, so it sits in their stomach and can’t be cleared out.
To help your dog keep their stool firm, look at low-fat foods. These will still offer beneficial fats (like salmon oil) but be under 15% Crude Fat to keep your dog healthy.
Your dog doesn’t have to suffer from loose stool. The dog foods on this list can help their digestion and keep diarrhea at bay.
In our opinion, the best dog food for firm stools is ORIJEN Six Fish Grain-Free Dry Dog Food.
But each of the formulas that we’ve listed contains fiber content, natural ingredients, and even prebiotics and probiotics. These are all essential potential food for firm stools.
