My very sick golden(stomach, kidney?!)

Please I need help for my dog that I can’t find in my country 😥 My almost 7 yrs old golden retriever is very sick. It started last Saturday by vomiting, then loss of appetite, diarrhoea, lethargy. He hasn’t eaten since Saturday and when drink he vomits. Here in Egypt it’s very hot and I am afraid of dehydration. The vet saw him, temperature was good, lost 2 kgs, asked for kidney& liver functions, blood parasitology, CBC. There was rise of creat. (7), microcytic hypochromic anemia, thrombocytopenia, leukocytosis. He gave him and asked me to continue this: ondansetron 8mg IV for vomiting, famotidine IV 20mg for stomach, vit. B comp. IV for sndmia, a renal support Medicine for pets, IV fluids (500 ml saline, 500ml lactated ringer, 400ml glucose 5/10%), flagyl 500 IV infusion for diarrhoea. Iron IM for anemia. The dog still has vomiting sensation lately with froth comes out, looks tired, no barking, diarrhoea comes out spontaneously, lately some jerky movements while sleeping, no eating but thirsty. And this bloody mucoid diarrhoea? I am afraid and sad. What should I do? Any advice/help? Thanks

Hello!  Usually when I read about an intensive care patient, I will want to know whether they are well enough hydrated.  I assess this using PCV (spun down in a tube) and total solids  in combination with knowing the heart rate and blood pressure.   I will also check whether the patient is anaemic, using a blood tube and not computer bloods.       I use Hartman's rather than lactated ringer's for dehydration. However I am on the other side of the world, do not know much detail about this patient (or the infectious diseases frequently seen where you are) and am probably not in a position to give your vets, who can see and assess their patient properly, advice. I think that if a second opinion is ok with your vets, the way for them to get one would be to speak urgently to one of the vetschools and find out how this is possible.  Since Covid, online consulting has become huge in the UK and they might be able to obtain advice and a second opinion about the case. Good luck - and do please let us know how things go at the end of this scary time.
