Emergency Hospitization for our Babyboy

Recently our dog got into a unknown toxin that we or the vets can't identify without further testing and bloodwork, He's having constant seizures to the point where he cant stand or walk so hes also having to to wear diapers and even broke a tooth from clinching down so hard during one of the seizures and we can barely get him to eat liqiud food or drink through a syringe. He was approved for insurance but theres a 2 week waiting period and we dont think he'll make it that long without help, They said the cost of having him hospitalized and to have all the tests and fluids would range from 2200-4200 and we are unfortunately dont make that kind of money nowadays if anybody can please donate anything it'd be a blessing for our Babyboy our family is PLEADING for help.
