Can Dogs Eat Hot Dogs? Salt, Fat & Toppings

Can Dogs Eat Hot Dogs?

AVOID

AVOID — Hot dogs are high in salt, fat and preservatives, and buns and toppings often contain onion. A tiny bite is unlikely to harm, but they are not a good treat.

Hot dogs are processed meat that is very salty and fatty, and the toppings and buns are often problematic. A small piece is unlikely to cause harm, but plain cooked meat is a much better choice.

If your dog ate a small piece of a plain hot dog, watch for stomach upset and offer fresh water. Contact your veterinarian if your dog ate several hot dogs, the toppings included onion or garlic, or your dog has had pancreatitis. If your dog vomits repeatedly, has a painful belly, or is very thirsty or very quiet, contact a veterinarian, or an emergency veterinary clinic out of hours, straight away.

Quick answer

Category: Meat
Recommended preparation: Not applicable — give plain cooked meat instead
Main concern: Salt, fat, preservatives, and onion or garlic in toppings and some sausages
Suitable as everyday food: No — not a good treat

The full answer

Hot dogs are a processed sausage made from ground meat with salt, fat, preservatives and flavourings. A small piece is unlikely to harm a healthy dog, and they are sometimes used as training treats in tiny pieces, but they are not a good choice.

They are very high in salt and fat. Too much can cause stomach upset or pancreatitis, and the salt can be a problem for dogs with heart or kidney disease. Some sausages also contain onion or garlic powder, which are toxic to dogs.

The bun and toppings add more problems: onions, ketchup, mustard, sauerkraut and relish are not suitable. If you want a meaty training treat, plain cooked chicken or a treat made for dogs is better.

We do not recommend hot dogs. If used as a rare training treat, cut a tiny piece, and prefer plain cooked meat.

How Should I Prepare It?

Not applicable. If using, cook, cool and cut into pea-sized pieces, removing any bun or toppings.

Can Puppies Eat Hot Dogs?

Puppies are sensitive to rich, salty foods. Choose plain cooked chicken or a puppy treat instead.

What If My Dog Ate Too Much?

Eating several hot dogs can cause vomiting, diarrhoea and excessive thirst, and may trigger pancreatitis.

If your dog ate a lot, or hot dogs with onion or garlic, contact a vet. Seek care for repeated vomiting, a painful belly or lethargy.
