Have Dog Health Questions? Ask a Dog Vet Online.
Hi, I am Dr. Peter and would like to help.
1- How much does your dog weigh?
2- How many grapes roughly did he eat?
If your dog is exhibiting any of the above signs have him checked by your veterinarian. But, according to my calculations, he is way below the toxic dose.
If you have additional questions I will be glad to answer them.
