Welcome to Justanswer! I am Dr. Altman and happy to assist you both today!

Luckily this medication is used in dogs. According to the veterinary formula

Carvedilol at an initial dose of 0.31 mg/kg (mean) PO twice daily and a target dose of 1.11 mg/kg (mean) PO twice daily is safe and well tolerated in dogs

So for your Maltese at 7 pounds (3.2 kg) this would be 1 mg- 3.5 mg twice daily

As you can see the 5.25 mg is almost double the advised dose for her size.

The clinical signs of toxicity included: lethargy (42%), bradycardia (21%), hypotension (8%), hypertension (8%) and tachycardia (8%)

With this possibility it would be best to induce vomiting if your dog ingested this within the last hour. You can induce vomiting with 3% hydrogen peroxide 1 tsp per ten pounds (i.e. 3/4 tsp) then walk around to mix it in the stomach and agitate the lining. If no vomiting within 10-15 minutes it can be repeated once only in hopes of inducing vomiting.

If no vomiting then please monitor for the symptoms above and if seen overnight please consider a veterinary er tonight

I hope this information makes sense but please let me know how else I can assist you both tonight. I am online another 30 minutes to assist you

Luckily toxic doses in rats and mice are much much higher that two times the normal dose so very likely you will simply see lethargy or gi upset with the ingestion but always best to know what to monitor for if you are not able to induce vomiting
