My dog it's been vomiting a stinky yellowish liquid since yesterday night. Is not eating just drinking water. It's been peeing normally but after yesterday afternoon is not pooping. It looks weak and I think some fever is going on. Can you help me?

I am very concerned about Pilly, it sounds like he has a very upset stomach! My top concern would be a blockage in his intestines caused by something that he ate, like a toy, bone, sock, trash, etc. This would also prevent food from moving through his system and turning into feces. Other possibilities include bacterial or viral infection, intestinal parasites, or other internal issue. I recommend that Pilly see a vet as soon as possible. Your vet will probably recommend x-rays and maybe even blood work depending on what they discover during the physical exam.

    I am so sorry to hear that Cooper is still not feeling well. I think you should find another available vet and discuss diagnostics and treatment that he may need, such as blood work, x-rays, or ultrasound. I would be highly suspicious of an intestinal foreign body or blockage; this will not improve with medications or injections, as you have seen. He is also likely very dehydrated at this point, you should also discuss in-hospital treatment for IV fluids with a vet.
