My dog had similar numbers, and she didn't get better after in vet fluids. I lost her in February. I had to help her with the suffering. I still miss her. Let us know how is your dog doing?
You could ask your vet's advice about palliative care including anti-nausea medication and particularly "Phosphorus binders".
There is no cure for kidney failure. But it can sometimes be slowed down with the right medication and diet. Sometimes a dog can gain more time and a decent quality of life for the time remaining. But of course if appetite has already gone and doesn't recover, then it probably is 'time'.
Pancreatitis of course, can affect appetite VERY badly, until the pancreas heals. That can take a little time.
Your dog may still have some options for a decent end-of-life care....
But of course, you know your dog better than anyone, and you will know when it is the right time to let her go.
If your dog was only diagnosed with pancreatitis four days ago she shouldn't be on food yet. The treatment for pancreatitis is to keep the dog on IV fluids ONLY for one week so that the pancreas can have TOTAL rest and not have to produce enzymes to digest anything. If you try to rush this healing procedure you will not have a favorable outcome. My best advice would be to take your dog to another vet for a second opinion and get your dog on strictly IV fluids until the pancreas had time to heal. The IV fluids will also help with the kidney failure because it will keep the body flushed with fluids.
