All Your Dog Needs at a Great Price

25% protein and 14% fat is right in the zone for most healthy, active dogs. If you happen to have a working dog breed like a Spaniel or a Husky, or if you take your dog hunting regularly that may not be quite enough for them, but it should suit almost all other dogs. 

It does contain potatoes, which could be an allergen for some. The other veggies include peas, lentils, kale, pumpkin, and carrots which are easily digestible. It also contains fruit such as blueberries, oranges, papaya, and coconut, which add a splash of vitamins and minerals that will help settle your dog’s stomach. 

It’s great for all life stages, and contains DHA to help puppies’ eyes and brain develop, and keep oldie’s mentally sharp. It doesn’t have joint supplements, though, so you’ll need to buy some separately if your dog needs.

These are awesome to feed your dog in between meals and they’re nutritious enough to be guilt-free. There are also only one or two ingredients in each, so they shouldn’t contribute to any extra dog farting.

Guilt-Free, Highly Nutritious 

These treats are raw nutrition, consisting of only one or two meat ingredients and a natural preservative. One of the best things about these little sausages is that they range from 13 to 16 calories each, depending on flavor. That means you can feed a couple of them to your pup happily in between meals, without worrying about overfeeding your dog. 

There are no carbs in these bites, but that’s not a problem. You also won’t find much in terms of added supplements, vitamins and minerals, or probiotics, but raw food is usually packed with Omegas. 

Remember, if your dog has food allergies or intolerances, you’ll need to make sure their treats avoid problem ingredients too. You can choose from six different flavors here, so even if your dog is sensitive to one, they’ll still have a couple of different flavor options.

Balanced, Complete Meal for All Dogs 

In addition to your healthy single protein and complex carbohydrates, there’s a good amount of Omega fatty acids which promote healthy digestion and less gas, as well as reduce chances of allergies, shedding, and other conditions like seizures

These are little cold-formed nuggets of antioxidants, vitamins and minerals that have been created by animal nutritionists and vets. They give a nice immune system boost to dogs of all life stages.

From Young to (Active) Older Dogs 

With 30% protein and 18% fat, this would be the best dog food for active dogs rather than inactive ones. It’s also fairly high in calories (438 per cup), but that’s not a problem for dogs who get enough exercise. Be sure to feed your dogs the right amount according to their body weight, though. 

It contains DHA, which is always a great addition to food as it keeps eyes sharp and brains sharper. There are also higher than average Omega fatty acid levels, which is awesome for easier digestion, as well as keeping your dog’s skin and coat healthy.

Taste of the Wild dog food is high protein, high fat, and has amazing Omegas, just without the addition of joint supplements.

You should check with your vet first before deciding to go with a glucosamine-free food!

Well-Rounded Dog Food 

This dog food isn’t missing anything else. It has a super protein level, a high fat level for active dogs, and retains a good calorie count (370 per cup). The Omegas are higher than average, which will help settle down digestive issues. 

Your dog will get a day’s worth of slow-releasing energy from sweet potatoes, potatoes, and peas in this food, and an extra dose of antioxidants from blueberries and raspberries (which also add a little to flavor). 

There are seven different sources of protein in this food, which can be a problem if your dog is allergic to a particular protein. Chelated minerals are also helpful for easier digestion, and the dog food contains a source of probiotics.

Best For Puppies

Probiotics & Prebiotics90%
Affordability85%

PROS

  • Probiotics added. 
  • Contains extra antioxidants, vitamins and minerals. 
  • Has a good level of DHA. 
  • Also contains glucosamine.

CONS

  • Chicken may disagree with some puppies.

Canidae PURE Real is a wonderful limited ingredient diet range, with dog foods for adults, seniors, and puppies, which is what we’ve picked for our gassy puppy choice. 

It has only nine ingredients, and although it comes in only one flavor (chicken), it should be fine for just about any puppy with gas. The recipe contains all a growing puppy needs to get big and strong and less farty.

click to see more

High Protein, Puppy-Specific Nutrients 

You’ll find 30% protein and 12% fat in this formula. Puppies need some particular things in a puppy food, and one of those is DHA, a fatty acid that is an important component of neural development in young dogs. 

There’s also a high level of glucosamine and chondroitin, which is useful for small breed and large breed puppies. Small breeds can be just as prone to joint dysplasia as large breeds, so don’t discount the importance of this supplement! 

Canidae also add probiotics to their dog foods, AFTER cooking to make sure it doesn’t lose any of its value.

Best For Seniors

PROS

  • Added probiotics for digestive support. 
  • High protein but lower in fat. 
  • Great Omega fatty acids. 
  • Added joint supplements and L-carnitine.

CONS

  • Not suitable for chicken or potato-sensitive dogs.

Just like puppies, senior dogs need a bit more support from their dog food than the average adult dog. This food remains high in protein, at 28%, and slightly lowered in fat (12%), which will help less active dogs. 

Seniors often become less active, but also tend to develop digestive issues with more gas. A lower fat count can aid in keeping their tummy happy, as too much fat can actually hamper the digestive process.

No Real Meat, But Good Nutrition 

There is no real meat in this food, which is a slight disadvantage as it tends to be easier to digest than meat meal. Chicken meal is the first ingredient and sole protein source, which means that if chicken doesn’t agree with your dog, you may have to find something else. 

There are plenty of fantastic fruits and vegetables to give your older dog sustained energy throughout the day. Fruits like blueberries and pomegranates add a dash of vitamins and minerals. There’s also dried kelp, which is a great ingredient for stimulating the thyroid and keeping it working. 

Your senior will also get a dose of Omegas, joint-strengthening supplements, and L-carnitine, which is wonderful for seniors as it helps with energy regulation and metabolism, reducing gas.

Testing Protocol & Criteria Used For Evaluation

Criteria #1: High-Quality Protein

Although protein is often the culprit in human farts, that’s no reason to feed your dog less of it. As long as the first ingredient in their food is a high-quality animal protein, their stomachs should be happy. 

The appropriate amount of protein in their food really depends on your dog. Anywhere from 18% and upwards is adequate according to AAFCO, although most dogs do best with 24% or more. Very active dogs do well with 30% or more, so you’ll need to match your dog’s lifestyle to their dog food. 

Be aware that dogs who struggle with gas may have food allergies or intolerances. You’ll need to see how they react to certain proteins, and if their tummy has a problem with any in particular. Chicken can be a common allergen, as can beef and lamb.

Criteria #2: Complex Carbohydrates

Although gluten-free grains are more easily digestible, it may be best to avoid them altogether as they tend to be high in fiber. An excess of fiber in a dog’s diet can contribute to gassiness, so we want to go as low as we can in fiber. 

Fruits and veggies are the best carb sources to choose. They have an adequate amount of fiber in them and also provide slow-releasing energy and vitamins and minerals. Potatoes can also often be an allergen, though, so be careful of this one! 

In general, sweet potatoes, squashes, and vitamin-rich fruits are the way to go.

Criteria #3: No By-Products

It’s crucial to choose a food that contains NO meat by-products. By-products are the offcuts of meat that contain indigestible things like beaks, feet, hooves, and stomach contents

These don’t count towards the protein content and generally have very nutritious value. They’re also often hard to digest, which will make farting worse.

Dogs with allergies will most likely respond badly to the presence of meat by-products, and even those without food allergies won’t get any nutritional value out of them.

Criteria #4: Probiotics & Prebiotics

Probiotics are live bacteria that live in a dog’s gut. They’re essential for healthy digestion. Prebiotics are fibers that feed these bacteria. 

Many dog foods have added probiotics and prebiotics, which is great to assist in digesting the food. Especially for dogs who struggle with gassiness, an extra dose of healthy gut bacteria can help speed things along in the intestine and prevent things like intestinal bacteria imbalance or intestinal parasites. 

Just be aware that prebiotics can feed unhealthy bacteria too, so it’s important that you take your dog to the vet if their stomach problems persist. If they’re healthy, prebiotics should help them stay that way, but if they aren’t, the vet can help them get their health back.

Criteria #5: Affordability

We’re all about making dogs happy, but they notice if their parents are feeling down! With that in mind, we added this criterion to make sure that pet parents know that feeding their pup a quality food doesn’t have to break the bank. 

We have a Best Value for Money option which is every bit as high-quality as the rest. We’ve also rated each food on this point so you can get an idea of which ones are more affordable and which are more pricey.


Questions & Answers

Why does my dog fart so much?

Dog farts are part of life as a pet parent, just like human farts are part of life as a human! They’re quite natural, and can be caused by a variety of things. 

The most common culprit is feeding them with poor quality dog food. Some commercial dog foods are loaded with unhealthy, indigestible ingredients that wreak havoc on your dog’s stomach. It could also be that they’re allergic to or intolerant of certain ingredients. This can be helped by choosing a limited ingredient food, but you may have to do some detective work first to figure out exactly what your pet is allergic to. 

Eating food that’s meant for humans could also throw your dog’s stomach out of whack. Often, human food isn’t easy for dogs to digest, and some can be downright poisonous for them. Eating these things could also cause an imbalance in dogs’ intestinal bacteria, which can lead to flatulence. 

Some dogs get overly excited about their food and can take a few big gulps of air in between mouthfuls. This can later be expelled as farts, although if your dog is one of these, there’s a very real danger of bloat. You can reduce the chances of this happening by feeding them smaller, more frequent meals during the day. 

Of course, there’s always a slight risk of a medical condition being the cause of dogs’ excessive gas. Some of these include intestinal parasites, irritable bowel syndrome, inflammatory bowel disease, or problems with the stomach, intestines, liver, or pancreas.

When should my dog’s flatulence be a concern?

If your dog becomes gassy and shows signs of discomfort such as whining, whimpering, sitting or lying in an unnatural position, or extreme lethargy, there could be an underlying problem. Other signs to look out for are diarrhea, struggling to poop, and blood when pooping. 

If your pooch displays any unusual signs in addition to throwing out smelly gas, a trip to the vet is advised to make sure everything is A-okay.

What should I look for in the best dog food to prevent gas?

The first ingredient in the best dog food for gas should be a high-quality animal protein. You’ll need to be sure to choose one that your dog’s stomach can deal with. Chicken, beef, and lamb can often be allergens, so they may not be the best choices for your dog. 

A grain-free diet is not completely necessary, but we recommend it for dogs who struggle with gassiness. Grains in food are harder to digest and also provide more fiber, which can contribute to flatulence. Look for dog foods with slow-digesting carbs like sweet potatoes, pumpkin, and squash. Potatoes can be great too, if your dog isn’t intolerant of them. A limited ingredient diet is actually a great way to go, and your pup won’t lose out on any nutrition. 

Probiotics and prebiotics are great to see in a dog food for preventing gas as they help regulate healthy gut bacteria. Omega fatty acids can also help with digestion so a high number is wonderful. 

Obviously you’ll want to see no artificial colors, flavors, or preservatives. It’s also essential to avoid by-products, and try to limit fiber ingredients.

What else can I do to reduce flatulence in dogs?

Apart from switching your pup to a healthy, fart-reducing dog food, there are other measures you could take to help decrease the chances of your dog turning into a smelly boy or girl. 

The importance of exercise can never be understated, but did you know it could help prevent gas too? Activity helps dispel gas that has built up, and the farts float off on a breeze without stinking up your home.

What should I do when my dog farts?

A dog’s fart interrupting your movie or relaxed evening is never fun, but it’s seriously important to be patient with your dog about their flatulence. Farts are such natural things that your dog most likely doesn’t even notice when it happens, even if it’s a loud one! 

Do NOT: 

  • Shout at your pooch (they probably don’t know what they did wrong). 
  • Spray air freshener (your dog could inhale it). 
  • Banish your pup to the yard. 

Do: 

  • Be aware that senior dogs pass more gas than young ones. 
  • Find a natural, non-toxic room spray. 
  • Remove your pooch from the area and spray. 
  • Open windows and fan the air as vigorously as necessary! 
  • Keep an eye out for other signs and symptoms.
