Classed as a vulnerable candidate for the coronavirus due to chronic obstructive pulmonary disease, Renee Hellman is quarantined to her home in the hope of not contracting Covid-19. That means the Colorado Spring, US, resident is unable to run her daily errands, such as picking up essential groceries. However, 7-year-old Sundance has proved he's a top pup by helping out his neighbour in need. The golden retriever's owner, Karen Evelth, trained her dog to make daily trips to Hellman's home. First, Sunny picks up a grocery list, and then returns later that day to deliver the items that Evelth has picked up at the supermarket. "He’s a hero for sure,” Evelth told CNN. “He does get his treats, he’s motivated by those. But he’s really special to me, and I’d be lost without him because he helps me so much. So I wanted him to help other people.” Evelth added that Sundance has been carrying out the task for several weeks, and will continue as long as her neighbour needs. “Karen’s a great neighbour, she watches out for me,” Hellman told Fox News. “We have to have something fun in our lives, and this is definitely fun." Sunny isn't the only pup helping others during the pandemic; one Chihuahua in Mexico made a trip to the local store to pick up a bag of Cheetos for his self-isolating owner. Owner Anthony Munoz claims Chokis ran across the street to the store, after he attached a note and some cash to his collar. "Hello sir of the store, can you sell my dog some orange – not red – Cheetos. In his collar he brings $20. If you don’t take good care of my dog, he will bite. From, the neighbour across the street," the message read. The pup was pictured making his way back from the shop carrying the single bag of crisps, according to a post on Munoz's Facebook page. The Mexican resident later told <i>Metro</i> that Chokis had since made several more trips to the local store.
