Hi, I'm sorry that Shilo is ill. My Piper (who is only 2) was born with congenital Kidney disease. I am not a vet but I have taken Piper to a specialist.
One of the main reasons that animals with kidney disease will not eat is an upset stomach. When my cats had kidney disease the vet had me give them famotidine (pepcid AC).
HOWEVER, the specialist told me that in the last 2 years research has shown that cats and dogs don't metabolize famotidine like humans do so she recommended 10 mg of omaprazole (Prilosec). It really helped Piper; her appetite returned.
However there is one catch. The over the counter Prilosec is 20 mg and the tablets are not scored and therefore can not be split accurately. I can't even begin to describe the warning I got from the specialist not to split those pills. Instead she wrote me a prescription for 10 mg omaprazole capsules.
This is Piper's daily medical routine:
Royal Canine LP (low protein) - canned food (of all the kidney diets Royal Canine is alleged to be the most palatable) and one teaspoon of Cesar Sunrise Canine Cuisine Smoked Bacon and Egg Wet Dog Food b/c she is a bacon fanatic. My thought was that our sense of smell is very important to how we perceive food and dogs have a much more keen sense of smell (but interestingly less taste buds) so Piper thinks she is getting the good stuff without me risking her kidney on food that is high protein.
10 mg of omaprazole (give in the morning and wait one hour before feeding)
100 ml SubQ fluid
Azodyl (Kidney supplement) 2 in the morning and 1 in the evening
Crananidin (Urinary tract supplement) 1 per day
Again, I am not a vet just a loving sheltie parent who takes one day at a time.
Wishing you and Shilo the very best!
Kimberly
