Not toxic, but close to the least useful meat you could share. Spam is a canned block of salt and fat with no bones or seasoning to complicate it, so the concern is straightforwardly quantity. The can is worth a separate thought: the peeled lid has a genuinely sharp edge.

Why Spam needs caution
There is no hidden hazard here, which is itself worth saying: Spam contains no allium, no bones, and no sweeteners, so unlike most cured meats it comes down to two ordinary things in unusual quantity. It is a salt-cured product and a fatty one, and dogs need far less sodium than people, with the ASPCA noting that excessive salt causes increased thirst and urination and, in large amounts, tremors and seizures, while Merck lists dietary fat among the risk factors for pancreatitis. The practical problem is that Spam is soft, strongly flavored, and comes in a slab, so a dog that reaches an open tin can eat a great deal very quickly. The packaging deserves its own line: the lid peels back into a thin metal edge, and a dog licking out a discarded can is the more likely injury on this page.

Signs to watch for
Increased thirst and urination, vomiting, diarrhea, abdominal discomfort; with a large salt load, wobbliness or tremors. From the can: bleeding from the mouth, pawing at the face, reluctance to eat

What to do next
Work out what fraction of the tin is gone rather than whether the dog got some. Account for the can and the lid separately and put them somewhere the dog cannot revisit. Leave water freely available and note your dog's weight and any pancreatitis or sodium-restriction history.

Salt, fat, and a sharp lid
Spam is unusual among cured meats for having no complicating ingredient at all. That makes the answer simpler, but it also removes the excuse for treating it as a harmless treat.
1. Quantity is the entire question
With no allium, no bones, and no sweetener, what is left is a salt-cured, fatty block. That means the honest answer scales purely with how much was eaten against how heavy the dog is. A thin slice is a salty snack; most of a tin in a small dog is a sodium and fat load worth a phone call, and the softness of the product means a dog can get through a lot of it fast.

2. Do not overlook the can
The lid peels off into a thin curl of metal with a sharp edge, and an emptied tin left within reach is exactly the sort of thing a dog will investigate with its tongue. Mouth lacerations from can lids bleed dramatically and can need veterinary attention, and swallowed metal is worse. Bin the can and lid properly before you start worrying about the meat.

3. It gets fed deliberately, which is the real risk
Unlike most cured meats, Spam is often given rather than stolen, sometimes routinely as a treat or to hide medication. That turns an occasional salt load into a habitual one, which is where sodium and weight genuinely start to matter. A small piece of plain cooked meat or a mild cheese does the same job with far less salt. Every deli and cookout meat, compared →
FAQ
No published toxic dose, and none needed to reach the point: a thin slice is a salty treat and a substantial portion of a tin is a serious salt and fat load, with the line arriving sooner the smaller the dog. Judge it as a fraction of the tin against body weight rather than by whether your dog had some.
A small slice given to or stolen by a healthy adult dog needs water available and nothing else. Expect some extra thirst, possibly a soft stool, and no other rich food that day.
Call for a large portion or most of a tin, for a small dog or puppy, for a dog with a pancreatitis history, and for any dog on a sodium-restricted diet. Call immediately if the dog chewed or licked the opened can, since a cut tongue or lip bleeds impressively and metal fragments are a real concern. Repeated vomiting, tremors, or a hunched abdomen all warrant a prompt call.
It is not toxic and a thin slice will not harm a healthy adult dog, but it is very salty and fatty with nothing nutritionally useful to offer. It is a poor regular treat, and a bad idea for small dogs, puppies, and dogs on sodium-restricted or low-fat diets.
Call your vet with an estimate of how much and your dog's weight. That much is a genuine salt and fat load, and in a pancreatitis-prone dog the fat matters as much as the sodium. Leave water freely available rather than restricting it, and make sure the can and lid are out of reach.
Check the mouth. The peeled lid and the can rim can be sharp enough to cut a tongue or lip, and those cuts bleed a lot. If you see bleeding, if your dog is pawing at its face, or if any metal is missing or bent away, call your vet rather than waiting.
