My dog is limping, vomiting, lethargic, and won't eat after park.

It could be that Sami overdid it on the walk, and that caused the limping. If she is back to normal with that, I'd keep an eye on her for now. I'm concerning about the vomiting, which isn't normal. Have her seen by a vet for this.

If he is laying down all the time and won't put his leg down, I can assure you he is in pain. I would recommend taking Sammy to the vet. He needs a thorough physical exam to determine where the issues could be coming from. X-rays may be needed to rule out fractures.

Severe, persistent vomiting should be assessed by a vet (especially if vomiting water for more than 12-18hours due to a risk of dehydration). It is possible he may have swallowed something while he was roaming which may have caused an obstruction or irritation. Given it happened within hours of coming home it is unlikely to be anything he contracted in the shelter

I am sorry to hear about Sam. It sounds like he is not feeling well at all. There are many different possible causes of vomiting in dogs. Some of the most common include ingestion of foreign objects, pancreatitis, ingestion of toxins, gastroenteritis, and more. You can read about vomiting at https://www.petcoach.co/article/vomiting-in-dogs/ . Due to the fact that he is very lethargic I would recommend taking him in to see a vet as soon as possible- to an emergency clinic if one is in your area if you feel he is very lethargic and continues to vomit. Do not offer anymore food and water tonight as he will likely just vomit it back up. The vet will examine him and may recommend x-rays or bloodwork to help determine a cause for vomiting and will most likely give injectable medication to stop the vomiting and IV fluids to help rehydrate poor Same.

If he was behaving normally otherwise, then watching him at home would have been recommended, but since he is lethargic as well, he really should be seen. It could be anything from a strain or pull to orthopedics injury to infection. A physical exam, xrays and a screening for tick borne diseases would be recommended. Treatment will depend on the diagnosis. In the meantime, restrict activity to just leash walks for elimination and avoid excessive running, jumping or rough play until he sees the doctor.

Pinto may have overdone it at the park today. It's concerning he vomiting in his sleep. Keep a close eye on him, and if he vomits again or has trouble walking when he wakes up, take him into a vet immediately.

Oh no! It sounds like Lela is painful on her right hind leg and needs to be evaluated for an injury or wound. The vomiting and diarrhea could be related to what is going on with her leg or could be caused by something else. I would recommend you take her in to your vet to be evaluated. She may need anti-inflammatories or pain medication for her leg as well as anti-nausea medication and diarrhea medication for her intestinal tract. With vomiting and diarrhea I also get very concerned about dehydration, so she may need some fluid treatment as well to get her feeling better. Good luck! I hope Lela is feeling more like herself soon!
