Hi. It's very important for your vet to diagnose the type of anemia - regenerative or non-regenerative (the latter being more likely), as that will dictate the type of treatment for it. Don't waste any time in getting your vet to to this
What anti-nausea medication has your vet prescribed? If any.
Portions of cooked chicken are not ideal, although can be sustaining for a short time. Only use human-grade (high quality protein) chicken and not dog food chicken. Also, use dark meat of chicken like the legs and thighs, as this has less phosphorous.
Try to encourage canned kd dog food like Hills kd, as that will help reduce toxin build-up and improve kidney function. Also, try to feed very small meals (literally a couple of desert spoons) every couple of hours. These smaller meals help reduce stress on the kidneys too.
Are you now doing SubQ fluid therapy at home? If not, this needs to start right away - talk to your vet. If SubQs are not done, the good work achieved by the IV fluids will subside very quickly. SubQ fluids are effectively maintenance and may need to be done daily for the forthcoming weeks - and possibly months.
Have a read of my article below - and ask any questions you may have when you have read it.
