Thank you for the additional information. It is not 'normal' for young dogs to get sick, every time there is something abnormal, like bright yellow stool, it needs to be investigated to determine what is going on. Bright yellow stool in a 3 year old dog is concerning, because this is something that can indicate liver damage or disease. This can occur for many reasons, including illness or ingestion of a toxin. At the very least, your dog should have a fecal sample checked, and some blood tests run to monitor liver and gall bladder function. I think having tests run now will be helpful in catching potential problems early on. Your dog should not have any intestinal parasites at his age, especially if he is on a monthly heartworm preventative (which also contains a dewormer). Even if some parasites were present they do not typically cause bright yellow stool. I really think that it's time to go back to the vet for a few tests. Please let me know if I can be of further assistance. If this has been helpful, please hit the green accept button. Best of luck with your dog :)
