Customer Question

What is the disease of Benadryl for a 31 pound labradoodle. She had a rabies vaccine today and has very significant diffuse swelling along her entire side of injection . No hives. I am an MD but have no idea what the dosage is for a dog. Any advice would be greatly appreciated.

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

I am so sorry that Lucy is having this reaction! The dose is 1 mg/ pound so for her size I would consider 25 mg 1 & 1/4 tablet and monitor for improvement within an hour. If there is no improvement she may require a veterinary er visit for a steroid injection but if there is improvement I typically will repeat in 4 hours then again every 6 hours for 24 hours

This might sedate as it does in people

You can also apply a warm towel to the area to hopefully increase circulation and get this to resolve the swelling faster. If the area is also painful you can rotate the warm with a cool towel, often with a 10 minute contact time for each

I hope this makes sense but please let me know how else I can do to assist you both today! I hope Lucy's swelling does resolve swiftly and definitely would talk to your vet about pretreating with benadryl in the future for rabies vaccinations

Good morning, I wanted to check on Lucy to see if the swelling went down from the rabies vaccination with the benadryl information I relayed? I would love an update when you are able!
