Brodie, who staff believe is between ten and 12 years old, came to Hilbrae Rescue Kennels at Cold Hatton Heath, near Shawbury, as a stray and was never reclaimed.
While the "typical old gentleman" of a dog has been a hit on social media, his age means he's often overlooked in the kennels.
Cheryl Gibson, of Shropshire Canine Enrichment, said the old boy wants nothing more than a quiet place to live out his retirement.
She said: "He's a typical old gentleman. All he wants is a warm bed and a little plod about, he doesn't ask for anything.
"He's invisible in kennels because he's quite vocal - he's got a proper grumpy old man bark. But he's just sad, he's really happy to be out of kennels."
Despite a video of Brodie's heartbreaking howl racking up over 10,000 views on TikTok in just three days, Cheryl says he's still waiting to find his forever home.
