She has threw up 3 times from yesterday til today and its yellow. Shes not wanting to eat or drink and is very weak as if in pain.

These systems are concerning and she needs to see a vet ASAP. The vet can check her over and may run some tests such as a blood test or abdominal scan. There are many possible causes for her symptoms including a gut obstruction, toxin ingestion, pancreatitis etc. The sooner we have her seen and start treatment, the better. Hopefully she is back to normal very shortly.

She threw up yellow liquid in the morning and has on/off heaved breathing. Also, went for her morning walk, seemed fine during and once she got home, ran for 2 minutes then laid down and hasn't gotten up.

Hello I'm sorry to see that your pet is not feeling well. Vomiting can be caused by dietary intolerance or discretion, a blockage or an infection. I recommend that you take her to a veterinarian for an exam. They may give her an anti-vomiting shot or run some diagnostic tests like lab work or x-rays. Good luck.

For two days my dog has been vomiting yellow tinged vomit sporadically. He also isn't wanting to eat much.

Hello- Thank you for your question. I’m sorry your pet isn’t feeling well. There are many different causes of vomiting and decreased appetite including G.I. obstruction, pancreatitis, toxin ingestion, or gastroenteritis, or cancerous causes. It would be best to take him to a veterinarian so they can examine him, run some diagnostics (x-rays and blood work) to assess the cause of his vomiting and provide IV fluids and anti-emetics to help him feel better. I hope he feels better soon.

I'm worried about my dog. He was acting fine yesterday and this morning but out of no where threw up yellow liquid. He threw up once and then tried again but nothing came out. I took him on a walk afterwards and he pooped a regular looking poop. He also doesn't have a loss of appetite. He has also been very tired after our walk. Should I be worried and take him to the vet?

Hello- Thank you for your question. If it was a single episode of vomiting yellow bile and your pup is otherwise acting normally then I don’t think you need to head to the vet right away. If he has more episodes of vomiting, stops eating, or becomes lethargic or continues to retch with no production of vomit then at that point you need to have him seen. Occasionally dogs will have an episode of vomiting but when it continues vet care is needed. I hope his symptoms don’t continue.

She has thrown up bile and water that she drinks this afternoon and night and hasn’t eaten all day. Is a vet visit necessary or will the stomach settle on it’s own?

Thank you for your question. If she is not able to keep water down and is continuing to vomit, it would be best to have her seen by a veterinarian, yes. Small dogs can become dehydrated quickly, and your veterinarian will be able to examine her and see what the problem may be. I hope that all goes well for her.
