Recommendation for a puppies last couple meals?

Everyone on Reddit and the internet seems to have senior dogs that have definitely experienced a lot.

Unfortunately we have a 11 month old dog and he was diagnosed with a cancer last Friday that isn’t curable with chemo and radiation, and my wife and I tried to stay away from table food at least until he was a little older but we don’t have that kind of time…

The vet said he has a couple weeks left but if I’m going to be honest that tumor on his cheek is expanding at such a rapid pace, I don’t even think he has a a couple months in him.

It’s truly heartbreaking how cruel the world can be but we want him to have the best days every day.

Today he had his own chicken filet from Chick-fil-A and a Pup cup.

What are your recommendations?
