At amounts a dog can reach in a normal household, this needs a vet or poison-control call straight away rather than watching and waiting.
Treat this as an emergency and call now. Stimulants are dangerous to dogs at small amounts: they cause agitation, a racing heart, tremors and a body temperature that can rise to a life-threatening level. Extended-release forms such as Concerta and Vyvanse keep releasing for hours, so a dog that seems settled can deteriorate later.
Call a vet or poison control now. Do not wait for symptoms.

Exposure details to have ready
These are the questions a veterinarian or poison-control operator will ask. Fill in what you know and leave the rest blank. This tool does not estimate a dose or a risk score: medication risk depends on the exact ingredient, strength, and formulation, so the assessment has to come from the clinician on the call.
- Keep the package, blister pack, or prescription bottle. The strength and the full ingredient list are what make the advice specific.
- Do not induce vomiting unless a veterinarian or poison-control professional tells you to. It is the wrong move for several medications and can cause harm on its own.
- Do not give milk, food, salt, hydrogen peroxide, or any home remedy on your own.
- Do not give a second dose of anything to make up for one you think was missed.
- Count what is left in the packet, so the number missing can be worked out.

Why ADHD Medication is dangerous
Amphetamine and methylphenidate drive the release of the body's own stimulant neurotransmitters. In a dog that produces restlessness, pacing, dilated pupils, a fast heart rate, tremors and hyperthermia, and it is the rise in body temperature that does the most harm. The margin between a therapeutic human dose and a dangerous exposure for a dog is small, so this is not a case where a single tablet is reliably a minor event.

Extended-release is the detail that changes everything
Concerta, Vyvanse, Adderall XR and similar products are designed to release over eight to twelve hours. A dog can look unremarkable for a while and then become severely affected, and the monitoring period is correspondingly long. Say the exact product name on the call, not just 'ADHD medicine'.
Overheating is the main danger
The stimulant effect raises body temperature, and it is hyperthermia rather than the racing heart that causes lasting damage. A dog that is panting hard, feels hot and will not settle needs to be seen now. Do not use ice or cold water without instruction; get to the clinic.
Where they come from
These exposures often involve a bag or a bedside table rather than a medicine cabinet, and frequently a visitor's prescription. If you are not sure of the strength because it was not your prescription, say that rather than guessing.
Signs to watch for
Restlessness, pacing, hyperactivity, dilated pupils, a racing heart, panting, tremors, high body temperature, vomiting, wobbliness; seizures and collapse at higher exposures

What to do next
Call first. Bring the bottle, note whether it is XR, ER, LA or Concerta/Vyvanse, and keep your dog cool and quiet on the way in.

A closer look at adhd medication
Amphetamine and methylphenidate drive the release of the body's own stimulant neurotransmitters. In a dog that produces restlessness, pacing, dilated pupils, a fast heart rate, tremors and hyperthermia, and it is the rise in body temperature that does the most harm. The margin between a therapeutic human dose and a dangerous exposure for a dog is small, so this is not a case where a single tablet is reliably a minor event. The details below use the specific facts for this exposure, rather than treating it like every other medication question.
1. Start with the exact exposure
For a closely related comparison, read Methylphenidate (Ritalin, Concerta). No threshold is given, and it would not help: the drugs differ, the strengths range widely, and the release profile matters as much as the number. What the vet needs is the name on the bottle, the strength, the count missing and the time.
2. Use the facts to decide whether to monitor or call
Another helpful reference is Antidepressants. Nothing at home, and do not try to calm the dog with anything of your own. Call immediately, before signs appear if possible. Do not induce vomiting unless instructed, especially in an agitated or tremoring dog. Immediately, for any suspected amount. This is an emergency-clinic situation rather than a wait-and-see one, particularly for extended-release products.
3. If the details are uncertain
Follow the first 10 minutes guide. Call first. Bring the bottle, note whether it is XR, ER, LA or Concerta/Vyvanse, and keep your dog cool and quiet on the way in.

Immediately, for any suspected amount. This is an emergency-clinic situation rather than a wait-and-see one, particularly for extended-release products.
Possibly, depending on the strength and your dog's size, and it is not something to judge at home. Call now: with stimulants the useful interventions happen early, and extended-release halves behave unpredictably when chewed.
With an extended-release product especially, that is expected early on and is not reassurance. Call at the time of the exposure rather than waiting to see what develops.
