Is grape seed extract in dog dental gel safe for my dog's liver?

Updated on September 23rd, 2025

Pet's info: Dog | Cavalier King Charles Spaniel | Male | neutered | 37 lbs

My 4 year old male Cavalier has had problems with elevated liver enzymes. X-Ray and Ultrasound images looked normal. Our vet advised us to discontinue his Trader Joe's dried chicken filet treats because they have been associated with problems. We wanted to ask your opinion about the safety of the product below. Gel Me: Doggy Dental Gel (4oz) Ingredients: Grape seed extract, grapefruit seed extract, peppermint oil, rosemary oil, neem seed oil, and thyme oil Thank you so much for your help.

As grapes and raisins are toxic to most dogs, and a cause has not been established yet, I would not give anything with grape ingredients. So personally I would not recommend this gel. If you want to give your dog a treat, boiled carrot pieces, green beans are great and healthy, and and if you want to give a commercial dental treat, Greenies are recommended.
