Can Dogs Eat Mushy Peas

Mushy peas are a familiar favourite on British plates—soft, savoury, and usually served alongside pies or fish and chips. But if your dog is eyeing up your leftovers, you might be wondering: can dogs eat mushy peas?

The answer is: it depends. Plain mushy peas made from just marrowfat peas and water are generally safe for dogs in small amounts. However, the moment salt, butter, or seasonings are added—as they often are—the answer becomes no. These extras can upset your dog’s stomach or even pose a risk to their health.

Are Peas Good for Dogs?

Peas themselves are a common ingredient in many dog foods. They’re a good source of plant-based protein, fibre, and vitamins like A, B, and K. In moderation, peas can support digestion, help maintain energy levels, and contribute to a healthy immune system.

However, mushy peas—the kind humans eat—are often processed or seasoned, which makes a big difference. The plain vegetable is one thing; the side dish version can be quite another.

What Makes Mushy Peas Risky?

Most shop-bought or takeaway mushy peas are made with added salt, butter, or flavourings. Salt in particular is something dogs don’t tolerate well. Even small amounts of excess sodium can lead to dehydration or, in more serious cases, affect heart and kidney health.

Some versions might also contain garlic or onion powder—both toxic to dogs even in small doses. And while butter may not be deadly, it’s high in fat and can cause stomach upset or contribute to weight gain and pancreatitis in dogs over time.

So, if you’re planning to share mushy peas with your dog, make sure they’re homemade and completely plain—no salt, no butter, no flavourings.

How to Serve Mushy Peas to Dogs

If you’ve got plain, unsalted, unbuttered mushy peas, a small spoonful can be added to your dog’s regular food. They’re soft and easy to digest, making them suitable for dogs of all ages.

Introduce them slowly, especially if your dog isn’t used to legumes, as too much too quickly can cause gas or mild digestive upset. And as always, moderation is key—mushy peas should be a treat or addition, not a regular staple.

Summary

Dogs can eat mushy peas, but only if they’re plain and free from salt, butter, and seasonings. While peas themselves are healthy in small portions, most human versions of mushy peas aren’t suitable due to added ingredients. If you’re keen to share, make them from scratch—and always keep portions small. Your dog’s tummy will thank you for it.
