Please help my dog he has heart failure & a brain bleed which is causing seizures and he needs blood, urine tests + MRI & CT

I own a miniature fox terrier who is around 12.5 years old. He has heart failure in both left and right valves and a brain bleed and it is causing seizures, he can have up to 5 a day. He is getting worse and he needs blood and urine tests, and MRI and a CT scan ($4,000-$5,000)

DX= MVD by eccho in the past DDX= r/o Thromboembolism /intracranial bleed /hepatobiliary/intracranial masses( growth) /idiopathic epilepsy. RECOMMEND Comprehensive Blood and urine tests, considering the MVD , age and current seizures going on for months ( LAST BLOOD TEST DONE IN NOV 2022--COMP PANEL CHEMISTRY & T4 ONLY ) Sick animal panel + CBC + T4 + cardiopet ProBnp + Bile acids Random + Full urinalysis + UPC + C and S + BP measure - Once these tests are ready / reassessed , then would need a CT/MRI ($4,000-$5,000) for further diagnostics into the seizures.

Liver disease ($600 ultrasound) + all medications

I am relying on the kindness of strangers to help my baby boy through this. I am asking out of the kindness of your hearts on behalf of my baby boy if you have anything that at all that I can put towards his vet bills we would appreciate it so much. My boys quality of life right is is very low, he is on a lot of medicines and it’s not until we can perform the tests we will know what to do next and how to help him.

We simply cannot afford that.. Please if you can help him he would be ever so grateful if he could thank you he would he’s such a good boy and he’s being so strong
