Tucker Budzyn , the Golden Retriever who built a massive online following, died unexpectedly Wednesday at age 8, according to his owner Courtney Budzyn . Courtney announced the loss in an emotional video posted Saturday, just days after sharing that Tucker had been diagnosed with lymphoma. Courtney said the cancer had affected Tucker’s intestines and that treatment initially helped him reach partial remission. His condition then deteriorated rapidly after a hole formed in an area damaged by the disease, leading to a serious infection despite veterinary care. The Internet’s Favorite Golden Retriever Tucker became one of social media’s most recognizable animal stars through expressive reaction videos, goofy sketches and everyday Golden Retriever chaos. His TikTok account grew to nearly 12 million followers, turning his fluffy face into a full-on internet institution. Courtney said Tucker was still swimming, playing and enjoying his favorite activities during his final days. Fans have since filled Tucker’s social media pages with tributes, proving that the beloved dog left behind a community far bigger than his own household.
