Hmmmmm.......this is a challenging case indeed.
It does not sound like your pet is in renal failure
To investigate acute and chronic renal failure:
Acute renal usually manifests with:
increased drinking/increased urination
fever (if infectious or bacterial cause)
kidneys painful when feel abdomen
vomiting and diarrhea
anorexia or decreased appetite
dehydration even though increased drinking
Diagnosis is made by:
history of compromised blood flow to kidneys or toxin exposure
see changes in urinalysis - remnants of cells being shed into urine
increased urine function indices called blood urea nitrogen and creatinine
intestinal protectants if toxin is involved
medications to control vomiting and diarrhea
Acute renal failure may improve with treatment, but the animal may never return to completely normal levels
This condition may require long-term management
If truly acute renal failure, the prognosis is guarded
To summarize all this, your dog would most likely be painful in her abdomen if she had acute renal failure
Chronic renal failure (CRF) is much more involved:
Usually see this in older pets, not 2 years as your pet is
The animal with CRF gets dull looking and listless; is weak; loses weight; loses appetite; usually has vomiting and/or diarrhea
animal is anemic due to factor produced by kidney called erythropoetin is lost; this is not then there to stimulate the bone
marrow to produce red blood cells
increased blood urea nitrogen and creatinine
see protein in the urine
supportive care - IV fluids, meds to control vomiting and diarrhea; artificial erythropoetin to fight anemia (stimulate production of red blood cells); Vitamin B supplements
CRF is irreversible; can only slow the progression of the disease
She is very young to have cancer, but it is still possible. If you feel hardness in her abdomen, abdominal ultrasound may be indicated to take a look and see if there is a mass associated with any of the organs. If see mass or suspect cancer, would want to immediately take x-rays of lungs to see if it has spread or metastasized there.
The possibility of liver cancer does exist and that could be what you are feeling. She would be lethargic, be losing weight, usually drinking and urinating
more, show jaundice or yellowing in the white of her eye
and pinna of ear
; many times can also see yellow in gums. Diagnosis of liver cancer is done by blood work, x-rays, abdominal ultrasound, and +/- liver biopsy. Depending on the type of cancer, you may have surgical treatment or chemotherapy or both. Treatment also involves IV fluids and good nutrition. These liver tumors have a guarded to poor prognosis.
GDV (gastric dilatation/volvulus): Not likely
She would be much worse by now if she had gastric dilation/volvulus, but can be checked out quickly with an abdominal x-ray to see if stomach is grossly enlarged. This is a dire emergency and progresses rapidly to shock and death
. I assume the vets you took her to were able to rule this out given the fact that the initial problem was 4 days ago.
What to do at home?:
You can give her buffered or baby aspirin for the pain at a dose of 5 - 15 mg/lb orally every 8-12 hours; this should be given with food if at all possible since aspirin is a non-steroidal anti-inflammatory or NSAID and could cause stomach ulcers on an empty stomach.
Offer her baby food - beef, chicken
Give her Pedialyte for hydration and electrolytes
Give her much love.
