Maybe. Hot dogs are highly-processed and frequently high in sodium and additives, which dogs don’t need in their diets. As an occasional snack, plain hot dogs are an acceptable source of protein. However, you must be extremely careful about feeding leftover hot dogs to your pet. Onions, a frequent garnish, are toxic to dogs. Many relishes and sauces also contain garlic, so they should be avoided.
If your dog has any unusual symptoms, talk to your vet about whether your dog could have a food allergy or intolerance. Hot dog buns, for instance, may trigger a reaction if your dog has a grain sensitivity. If your dog consumes onions or garlic, seek immediate veterinary care.
