Not toxic, but it is close to the saltiest way to give a dog pork. Prosciutto is cured with little more than salt and time, and because months of drying remove much of the water, what remains is salt concentrated into a small weight of meat. The thin slicing is genuinely the redeeming feature.

Why Prosciutto needs caution
Prosciutto is a study in simplicity: pork, salt, and a long wait, with none of the rubs, sugars, or aromatics that other cured meats carry. That simplicity is exactly what makes it salty. Drying removes a great deal of the water while leaving the salt behind, so gram for gram the finished ham is far saltier than the fresh pork it started as, in the same way that drying concentrates anything else. Dogs need considerably less sodium than people, and the ASPCA notes that excessive salt produces increased thirst and urination and, in large amounts, tremors and seizures. Working in the other direction is the way it is served: prosciutto is sliced almost transparently thin, so a stolen slice is a very small weight of meat, which is why most single-slice incidents pass without event.

What to do next
Estimate the weight rather than counting slices, since prosciutto is sliced thin enough that the two figures diverge sharply. Note your dog's weight and any heart or kidney condition. Leave water freely available: restricting it after a salt load is the wrong instinct.

Salt, time, and not much else
Most cured meats are a list of ingredients. Prosciutto is essentially two, which makes it the cleanest illustration of why curing itself is the thing to think about.
1. Drying concentrates what stays behind
Months of air-drying remove much of the ham's water while the salt remains, so the finished product carries more sodium per gram than the fresh meat ever did. This is the same arithmetic that makes dried onion more concentrated than fresh onion, applied to salt instead of an allium, and it is why a small piece of prosciutto is saltier than a similar-looking piece of roast pork.

2. Thin slicing is doing a lot of work
The reason most prosciutto incidents end quietly is portion size rather than mildness. A slice you can see through weighs very little, so the salt that comes with it is limited too. That protection disappears the moment a dog gets the packet rather than a slice, which is the version of this incident worth calling about. Ham and dogs →
3. Prescription diets change the calculation
For a healthy adult dog a slice is a poor snack and nothing more. For a dog whose heart or kidney disease is being managed with a sodium-restricted diet, the same slice can undo careful work, and it is worth mentioning to your vet even if the dog seems entirely well. Say what the dog is being fed when you call, not just what it stole. Every deli and cookout meat, compared →
FAQ
No toxic dose is published for cured ham, and the weight involved is what matters rather than the number of slices, because prosciutto is sliced so thinly that several slices can weigh very little. A slice off a board for a healthy adult dog is a salty snack. A dog that reached a whole pack has eaten a substantial amount of salt in a form that does not look like much.
One or two slices taken by a healthy adult dog is a monitoring situation at most. Leave water freely available rather than restricting it, and expect some extra thirst and possibly a loose stool.
Call for a whole pack, for a small dog or puppy, and for any dog on a sodium-restricted diet for heart or kidney disease, where a salty theft matters more than the quantity suggests. Call promptly for repeated vomiting, wobbliness or tremors, or drinking and urinating that seems excessive even after a salty meal.
It is not toxic, but it is one of the saltier things in a fridge and there is no nutritional reason to offer it. A single thin slice will not usually trouble a healthy adult dog. Avoid it entirely for small dogs, puppies, and any dog on a sodium-restricted diet.
Yes. A full packet is a meaningful salt load even though it weighs little, and the risk scales against your dog's body weight. Leave water freely available, do not restrict it, and call with an estimate of the pack weight and your dog's size.
Gram for gram it is generally saltier, because drying concentrates the salt while cooked ham retains more water. The practical difference is smaller than that sounds, since prosciutto is served in much thinner slices. Neither belongs in a dog's regular diet.
