Mack, a much-loved mutt in Michigan, spent this past week as he has spent the last 10 years — hanging out with the regulars at O’Duffy’s Pub in Kalamazoo, enjoying his favorite snacks and the company of friends.

Last Sunday, though, was Mack’s last Sunday — the 13-year-old German shepherd-collie mix is scheduled to be euthanized today after vets found a large tumor on his liver and other complications.

Jamie Kavanaugh, owner of O’Duffy’s Pub/Cosmo’s Cucina, took Mack to the veterinarian Tuesday and received the diagnosis. “His body is shutting down,” Kavanaugh said.

Mack spent most every day of the last 10 years at the Irish pub in Kalamazoo’s Vine neighborhood, according to MLive.com.

“He’s been a big, calm boy for all of his life. He’s very laid back, good with other dogs, people, kids. He’s very tolerant and loving,” Kavanaugh said. “He’s enjoyed being here. He makes his rounds, eats some treats. St. Patrick’s Day won’t be the same without him.”

Since learning of Mack’s illness, Kavanaugh said he’s showered the dog with companionship and treats. On Wednesday night, when Mack stopped by the pub, a customer ordered a filet and gave the first bite to Mack. Kavanaugh planned to bring Mack to the pub last night for a final goodbye.

“The number of people who love this guy, I can’t imagine what the actually number is. It’s people I don’t even know who love him, that come here and enjoy his company. It’s a real testament to the love of this community,” Kavanaugh said.

Kavanaugh lost his wife, Kim, the restaurant’s co-owner, just over two years ago

“When my wife passed away … I was really afraid he was going to follow her. Instead, he stuck by my side, stayed by my side and he’s been with me on this journey ever since,” Kavanaugh said of Mack. “Now, I think he feels his work is done. And he’s tired. All I can do is pass the love on.”

Kavanaugh said he plans to have Mack cremated and may take his ashes to Ireland to scatter off the coast of the Irish Sea.
