Buyers Guide to Smelly Dog Poop Food

Just like all living things, your dog is also going to poop. Yes, this is one of the more unlikely facts, but it is something that is simply not avoidable. What is avoidable though is the fact that you don’t deal with smelly, intolerable poop that stinks the entire house. And no, making your canine buddy poop outside is not the only solution!

What you need to understand more than anything else is what you poop is what you eat. It is the same case with your canine buddy. If they are not eating the right things, their poop will also come out bad. So that is the problem that you need to fight in order to eliminate odor from their feces.

What the Poop?

If your dog has been pooping like they had the worst kind of seafood, then chances are, there is some story going inside their digestive tract that you are totally unaware of. A normal stool passed by a healthy dog is one that is firm, brown colored and has only a mild smell. If the smell of the stool is truly unbearable, it means there is something wrong.

The bad odor is there when there is too much sulfur present inside the intestine at the time of bacteria breaking food molecules. The more hard work those bacteria have to put in to break apart food molecules, the more sulfur there will be and the worst smelling poop will come out. Some common reasons for smelly poop include infections of the digestive tract, malabsorption syndrome, parasites, and irritable bowel syndrome.

So these are the things you need to target and get rid of in order to make sure that the smell of poop is eliminated. If you feel that your dog is going through some kind of stomach problem, it is best to take them to a vet so that accurate diagnosis can be made in a timely manner.

What they Eat is What they Poop

The more time it takes for your dog to digest his food, the more sulfur buildup there is in their stomach. Hence the stool will stink more. If your dog has been consuming food items that contain a lot of fillers like meat byproducts and grains, then they will have difficulty in digesting them quickly. The whole point of fillers is to keep your pup feeling fuller for longer, which is why it can take up to 48 hours to digest.

These kinds of indigestible ingredients like cellulose, take a lot of time to be digested and result in smellier poop. This is why you should opt for a grain-free diet that has no elements of corn, wheat, soy or by-products. Opt for food formulas that contain high amounts of protein, moderate fats, and low carbohydrates so that your dog has an easier time digesting everything he ate.

Raw Diet is Better for the Smell

There is no denying the fact that raw diet produces less smelly food. This is because dogs take no more than 4 to 5 hours to digest this raw food, while the commercially produced food, one that contains fillers, can take around two days to digest.

Therefore, raw/cooked meat is easier to digest because that is what their systems are best attuned to. According to many experts when dogs are given 100% raw diets, their stool is almost smelled free, and firm. There are even times when there is zero smell.

This is the reason why you need to be very careful when selecting dog food. Even if you are going with commercially produced food, make sure it does not contain fillers.

Probiotics are Best!

There is simply no denying the many advantages of probiotics. They are the good bacteria that aid in digestion inside your dog’s digestive tract. They help in digesting the food quickly so that the food comes out smelling very little.

If you plan on giving commercially produced food, opt for probiotic supplements as they will ensure that the gut health of your dog remains perfect. Opt for a probiotic that contains at least 10 strains of bacteria.

There are many available in the market. One more thing you can do is to read the label of the dog food carefully. Does it say that the supplements present include probiotics? If yes, then that is the food you should opt for, because it will increase the good bacteria in your dog’s stomach and speed u digestion and metabolizing of food.


The truth of the matter is, you as the pet parent are the ones who will have to keep an eye out for how well your canine pal is faring. If the poop suddenly becomes more smelly, then you need to get in touch with a vet immediately. It could be a sign of some underlying health condition that needs to be dealt with.

If that is not the case, then try to change what food you have been giving them. If you feel that the food is good enough, opt for a probiotic supplement to improve their digestion and eliminate the smell from their poop. Good luck!
