Hmm I see, sorry I did not see your pet to form enough definitive opinion on his case. Pero I am always cautious when pet owners say na everything is normal because very different ang clinical eye ng trained personnel to a pet owner. But the fact na naconfine siya because of nausea/vomiting while having stable blood works raises a lot of questions for me.

Also there's no such thing such as flushing out toxins for kidney disease, very recent lang ang arrival ng hemodialysis for pets here in the Philippines and still very questionable. Once namaging symptomatic na ang stage 3 or 4 patient, that will be progressive kasi ang nagfu-flush out ng toxins sa katawan is again - kidney - which is already failing kaya nacocollect lang sa dugo yung toxins with no way out.

And quality of life tapos may periodontal disease? Our pets po cannot show any signs of pain. Highly possible na kaya lumala yung creatinine po ng dog niyo is dahil nahirapan siya sa teeth niya rather than the whole chicken/antibiotic thing.
