My 15 lb beagle just chewed a big mouthful of cocoa mulch and seems wobbly — what do I do first?

Short answer

Yes, this is an emergency. The wobbliness is a sign of neurological effects from the theobromine. Grab the mulch bag or a sample of what he ate to show the vet. Call your vet or the ASPCA poison line at 888-426-4435 right now — do not wait for more symptoms. Keep him calm and quiet on the way to the clinic; excitement can worsen a racing heart.

Why wobbliness changes everything for your 15 lb beagle

The unsteadiness you're seeing means the theobromine has already started affecting his nervous system. Unlike early signs like vomiting or restlessness, loss of coordination shows the toxins are disrupting basic motor control. At his weight, even one mouthful of cocoa mulch can deliver a dangerous dose because the rough texture makes it hard to spit out once chewed.

Right now, his body is struggling to metabolize the stimulants in the cocoa shells. The wobbliness may worsen to full tremors or seizures if untreated. Avoid giving water or food, as nausea could lead to choking if he's disoriented. Keep lights low and noise minimal during transport — sensory stimulation can worsen neurological symptoms.

What the vet needs from you immediately

Grab any remaining mulch or the packaging to show the clinic. Different brands vary in cocoa concentration, and some contain added fertilizers that complicate treatment. If you can't find the original product, scrape a sample from where he was chewing — even wet fragments help identify the source.

Note the approximate time of ingestion and any changes in his behavior leading up to the wobbliness. Did he vomit first? Was he panting or pacing beforehand? These details help the vet gauge how quickly the toxins are absorbing and whether to expect worsening symptoms en route.

The critical first 90 minutes after wobbling starts

Neurological signs typically appear later in cocoa poisoning cases, which means his system has already absorbed a significant amount. Your beagle may seem temporarily more alert after the initial wobbliness, but this doesn't mean he's improving — it often precedes another wave of stronger symptoms.

Expect the veterinary team to monitor his heart rate closely upon arrival. The combination of neurological and cardiac effects makes cocoa mulch particularly dangerous compared to other garden hazards. They'll likely administer medications to protect his heart and control tremors while preventing further toxin absorption.

Why excitement worsens theobromine poisoning

The stimulant nature of cocoa means stress and activity accelerate its effects. Car rides already elevate a dog's heart rate, and in this condition, that added strain could push him into dangerous arrhythmias. Carry small dogs to the car rather than letting them walk if they're unsteady.

If he starts seizuring during transport, cushion his head with a folded towel but don't restrain the movements. Time any seizures and report their duration at the clinic. Even brief convulsions change the treatment priorities, so the vet staff needs this update the moment you arrive.
