Can CoQ10 prevent heart disease in my Cavalier King Charles Spaniel?

Updated On September 23rd, 2025

Will adding coq10 to my dogs diet help prevent her from getting heart disease? She's a cavalier King Charles spaniel and is prone to heart problems. I will give it if it will make a difference but I'm already giving multiple supplements so I'm not sure it's necessary? Thanks! ( the supplements I give are: Fish oil, probiotics and enzymes and joint pill)

Unfortunately, this Coq10 will not prevent her from getting heart disease. There's no harm in giving it to her, but as you've said, the cavalier King Charles spaniel is prone to heart disease genetically. Supplements do not change her genetics, but you can help her heart health by making sure she isn't obese and has plenty of exercise.
