Euthanasia for my beloved beagle Petey [View all]

Monday after our Petey was deathly sick all night our vet told us that he has a large tumor on his liver. They gave us two antiemetics and an antibiotic. So he's not vomiting anymore and after a day or so he seemed to return to normal. He's 13 years old.

The vet says we don't have to put him down now, but I know we will soon. Here's my worry. Our Jack died in 2015 from Lymphoma. He took a turn for the worse on a Friday night. Our vet back then had Saturday hours but we had a very long 12 hours between when his illness became painful and the vet's office opened.

For when Petey's time is up, is it reasonable of me to ask the vet for a serious pain killer to tide Petey over until we can get him to the vet when they open? I can't stand the thought of him suffering all night like our Jack did.

Hoping some DU pet lovers can offer some advice.
