OH GOSH, I’m so sorry about your darling Buddy, but I think 12-13 years is a pretty good run for his breed and he has the best of care and love with you two. I know that our Pug, Jack, surprised everyone when he lived till age 19 because Dr. O cooked him liver every night...lol. Jack refused to eat anything else after Dr. O passed him a piece of liver from his plate one night. I’d toss canned spinach in with his liver once a week and he’d eat that, too, provided the liver was cut into smaller than usual pieces. I keep forgetting to buy liver while I’m at the store. (Louie is a very fussy eater).
