What Are The Best Puppy Foods For Sensitive Stomachs?

puppy sensitive stomachWhat should you do if your puppy can’t keep his food down? How can you tell if you’ve got a puppy with a sensitive stomach? And why, oh why, won’t your little puppy eat his food?

No puppy mom or dad wants to see their little one suffering, so a puppy with a sensitive stomach is probably something to sort as soon as possible. It’s actually quite common for puppies to have more sensitive stomachs than their adult counterparts, as a lot of the time this is due to their still-developing immune and digestive systems. We understand that it can be a little stressful, but a lot of the time it isn’t a reason to panic.

Luckily, with a few dietary changes and puppy foods for sensitive stomachs, we can often have this under control quite quickly. We’ve put together some of the signs that your puppy might have a sensitive tummy, as well as some of the market-leading brands that offer potential solutions.

 How do I know if my puppy has a sensitive stomach?

It is possible that your puppy has a sensitive stomach if he’s:

  • Vomiting (either immediately or a little later);
  • Passing a lot of gas;
  • Suffering from diarrhea or loose stools; or
  • Feeling itchy and scratching at sensitive spots on his body.

But what to do about it? If you’re worried because these symptoms are particularly serious, then you should take your puppy straight to his vet. Fairly often, however, milder forms of these indicators often just signal a sensitive stomach. Which can be uncomfortable for your puppy, but nothing to panic about.

A lot of the time, a sensitive stomach can be the result of your puppy being intolerant or sensitive to particular ingredients. Not to be confused with allergies (which are far more serious and require immediate vet attention), sensitivities and intolerances will require your puppy to avoid certain ingredients. He will most likely need to switch to puppy foods for sensitive stomachs.

What are the characteristics of a limited ingredient diet?

best puppy food sensitive stomach‘Limited Ingredient Diets’, or ‘Limited Diets’ are often just ways that different brands describe puppy foods for sensitive stomachs. These foods generally use ‘novel’ proteins and/or cut out different ingredients that commonly trigger adverse reactions. Some examples include puppy foods for sensitive stomachs that:

  • Are grain free – and so include zero wheat products, corn products, or soy;
  • Feature a single protein source – so puppy owners can know exactly what is (and, more importantly, what isn’t) in their best friend’s food;
  • Feature ‘novel’ protein sources – such as venison, bison, or rabbit, rather than chicken or beef;
  • Use hydrolyzed vegetable proteins rather than meat – for puppies who may have more than one meat allergy.

So while it may sound super-complicated, it’s actually the exact opposite! A lot of the time, puppies with sensitive stomachs will just need to steer clear of whatever ingredient is triggering their symptoms and they’ll be A-OK.

How do I keep my puppy healthy if he has a sensitive stomach?

First and foremost, give him high-quality puppy food that’s designed especially for his specific needs. There are also several things that your vet might suggest, including:

  • Making sure your puppy’s getting balanced amounts of fiber in his diet, for easier digestion. For puppies who can handle gluten, whole brown rice and oatmeal are often good examples of gentle fibers.
  • Keeping track of what your puppy eats. If you know what your fluffy friend ate before he felt off-color, you may be able to pick up on trends or patterns that can help you avoid certain foods.
  • Avoiding overexposure to one specific protein. Puppies have still-developing digestive and immune systems. When they eat the same meat-based protein over and over without variety, they may be more prone to developing a hypersensitivity to it.

Q: Why do puppies get sensitive stomachs?

A: As mentioned, some puppies may have allergies to specific ingredients, while others may be intolerant. Some common ingredients that can trigger the symptoms of intolerance are grains such as wheat, barley, or corn. Somewhat surprisingly, meats such as beef and chicken are among the ‘usual suspects’ when a puppy is having reactions like gas, diarrhea, vomiting, or even itchy skin and ears.

Every puppy or dog is unique, but some breeds are more susceptible to intolerances than others. Terriers like Yorkies may be more likely to develop sensitive tummies over time and need to stick to a puppy food for sensitive stomachs. It’s possible that the condition may become more pronounced over time—but don’t worry. With a good start on a sensitive puppy food, you’ll be doing the best you can for your fluffy friend.   

Q: Can I give my puppy table scraps if he has a sensitive tummy?

A: Generally, it’s not a great idea to encourage your puppy to share your dinner by giving them table scraps. It’s even more strongly suggested that you avoid this if you’ve got a puppy who has a sensitive stomach. With a complete and balanced puppy food for sensitive stomachs, your little one will already be getting all the nutrients he needs for healthy development. He’ll also be getting all the calories he needs for growth and feeding him table scraps can contribute to obesity.

For pups who already have sensitive tummies, it’s possible that feeding little bits from your meals may make the problem worse. Without a complete list of ingredients that are triggering his symptoms, you may end up accidentally feeding him something that sets off an intolerance.

Q: With so many sensitive stomach puppy foods, how can I pick the best?

A: Good question! We’ve tried to cover the many needs of different puppies – namely larger breeds, small breeds, and those who prefer wet foods. If you’re not sure which one your puppy enjoys best, it’s a good idea to experiment. There’s no harm in trying one brand one month, and a different brand the next, if you make the change over a week or so. Just try not to give your puppy’s little tummy any more shocks than it has already been through!

When switching your puppy over, try to do so by mixing in some of the new puppy foods for sensitive stomachs with the old. Gradually increase the amount of new food each day till he’s completely on the new food.

What should you do if your puppy can’t keep his food down? How can you tell if you’ve got a puppy with a sensitive stomach? And why, oh why, won’t your little puppy eat his food? No puppy mom or dad wants to see their little one suffering, so a puppy with a sensitive stomach is probably something to sort as soon as possible. It’s actually quite common for puppies to have more sensitive stomachs than their adult counterparts, as a lot of the time this is due to their still-developing immune and digestive systems. We understand that it can…
