Help save cooper

Hello... Introducing my naughty basset/corgi baby. I am not one to ask but, my fur baby Cooper Ralph Garrett ingested about 16oz of lethal rat poisoning. The vet said that this is a poisoning that has no antidote but because I rushed him in as soon as I did they were able to get him to vomit up about half. They told me the prognosis is good if they can keep him hydrated and pump full of charcoal to prevent him from absorbing the remaining poison. If he doesn't get this treatment he will suffer neurological problems and begin having seizures and eventually pass. The bill for this inpatient stay is more than what I was approved for with a payment plan and I am unfortunately already living paycheck to paycheck.... in fact I am a little embarrassed that I am asking for help this publicly. He is my child though and I am struggling financially. We brought cooper home while I was pregnant and he has been my daughter's best friend. He is our family. He has become a therapy dog for myself. He has many years ahead of him being a big brother. If you could spare to help or share this, my little family would be extremely grateful.
