I err on the side of caution because CoQ10 can be a bit stimulating.
Izzy weighs about 60 pounds and I give her 30mg.
She’s had 50mg with no problems but I reduced the dosage once she started showing improvement.
Way down at the bottom of this page is a recommended dosage chart for dogs:

I’d start on the low side, if it were my dog, until I saw how it reacted to it.
Hug ol’ Molly for me....:)
Thank you. I bookmarked the page with the dosage. I only had 50mg CoQ-10 so I punctured one capsule and squirted part of it into her food. So far, so good. Molly is a character. I want to keep her with me as long as I can.
