Heroes come in a variety of sizes, forms, and species.

As Russia’s invasion of Ukraine enters its third month, a 2-year-old Jack Russell Terrier named Patron is being praised for his efforts to save lives.

Russian soldiers started a large-scale invasion of Ukraine on February 24, the first significant land battle in Europe in decades.

Patron sniffs for bombs left over after Russia’s strikes as part of his job with State Emergency Service (SES) rescuers in the northern Ukrainian city of Chernihiv, according to NPR.

Patron has helped defuse around 90 explosive devices since the invasion of Ukraine began, according to the news agency.

Brave Patron’s abilities and lovely appearance have earned him a large following on social media.

On Tuesday, the Ukrainian State Emergency Service published images of Patron for his followers to enjoy on Facebook, including one of a toddler petting the renowned dog. The pet is known as Patron, the organization’s pyrotechnic dog, and is adored by both adults and children.

The Centre for Strategic Communications and Information Security published a video of Patron working in his safety gear on Twitter on March 19.

The invasion, which was authorized by Russian President Vladimir Putin, has sparked worldwide outrage and increased economic penalties on Russia.

Various nations have committed assistance or military support to the opposition as NATO soldiers assemble in the region around Ukraine. President Volodymyr Zelenskyy of Ukraine called for peace negotiations, which have so far failed, while also pushing his country to fight back.

Putin maintains that Ukraine has historic links to Russia and that he is working in his country’s best interests. Zelenskyy pledged that he would not yield.
