Why beta‑blockers are dangerous
Beta‑blockers block adrenaline receptors and depress cardiac function.
A dropped pill on the floor near a dog’s bowl can be easily scooped up during a quick snack.
They can cause sudden low blood pressure and bradycardia.
Why speed matters
Delaying care significantly worsens outcomes. Some signs appear hours or days later, so "looks fine right now" is not a reason to wait.
Symptoms of beta-blocker-overdose poisoning
- slow heart rate detected within 30-60 minutes
- weakness and difficulty standing by the hour
- pale gums and cool extremities
- excessive drooling and mild vomiting
- collapse or fainting may occur
- abnormally low breathing rate
What to do right now
- call your vet or the Pet Poison Helpline right away
- bring the medication bottle or any remaining tablets
- watch the pet’s heart rate and keep it quiet and warm
- do not induce vomiting if the pet is unconscious or severely bradycardic because aspiration risk
- rush to an emergency veterinary clinic for IV fluids and cardiac monitoring
