Havoc should be absolutely fine after ingesting the Proin tablet! He ingested approximately 4.4 mg/kg (milligrams per kilogram of body weight), and more serious signs of toxicity usually occur with doses over 15 mg/kg. There is a chance that Havoc may experience agitation, vomiting, decreased heart rate or elevated blood pressure. While these signs generally resolve within 24 hours of ingestion, it would be ideal to take Havoc to his vet for an exam and blood pressure measurement. I hope this helps!

    Hi and thank you for using Petco Pet Education Center, formerly Petcoach. Allie received roughly around a 3.7 mg/kg dose of Proin. According to the ASPCA, dogs that ingested this much can be normal or they can have a slow heart right and high blood pressure. If Allie shows any signs of agitation or restlessness, vomiting, diarrhea or lethargy, I would take her into the emergency veterinarian tonight. She may need fluids and activated charcoal.
