It was a big deal when this golden retriever completed his chemotherapy treatment, so when the big day finally arrived, he was rewarded with the most adorable graduation ceremony imaginable.

TikTok user Brenna Stout (@brennastout) from Orange County, California, shared the footage of her English cream retriever, named Dunder, as he was applauded by several members of the veterinary clinic for finishing chemotherapy treatment.

While making the most of his graduation ceremony, the 6-year-old pup sported his very own mortarboard and was rewarded with a special dog cake just for him. Needless to say, there was nothing wrong with his appetite and he lapped up every last crumb of his delicious treat.

The adorable clip has melted hearts across the internet and there’s hardly a dry eye left on social media. Since it was posted on May 29, the video has amassed more than 5.9 million views and over 1.7 million likes on TikTok.

The caption alongside the video reads: “We’re so proud of him, we love you Dunder!”
