Is there a natural remedy, or diet that can help my very sick chihuahua ?

I have a 22 month chihuahua that was the picture of health 2 months ago. He weighed 6 lbs then, and now he's down to 4/1/2 lbs. He was given 4 vaccines all at once: lepto,rabies,DHPP, and bordetella. He developed an egg size cyst on his rear,and his penis swelled up 2x,and wouldn't retract. His personality changed,and he became agressive. I cannot touch him on his side or he screams, and his salivary glands swelled up so large that he cannot swallow without extensive pain. He cries and has been vomiting for 2 months. I have spent thousands of dollars in emergency vet care, as well as seeing 3 different vets and an internal specialist. They have run all kinds of tests,biopsies, iv's, as well as put him on steroids,anti vomiting medicine,phenobarbatal, etc. I have cried, and watched him deterioate before my eyes, and all these so called vet specialist's have no answer to give me. He now vomits up white/yellow froth. Is there a holistic remedy,that can help me? "PLEASE". Thank you.

Im so sorry to hear that, I am a CVT (certified veterinary technician) and from what youve said it seems like he had a bad reaction to the vaccines that permanelty did damage. I see this happen sometimes, that is why I do not vaccinate any of my animals and that is why I do not vaccinate myself. As far as hollistic treatments it seems as though he is to far gone. But there are hollistic veterinarians, maybe you should try to look one up.

Best of Luck!
