She’s been throwing up, popping (diarrhea), heavy breathing, can’t walk without limping, collapsing and etc
I'm truly sorry to hear that Mocha is experiencing such distressing symptoms. The combination of vomiting, diarrhea, loss of appetite, difficulty breathing, and collapsing is quite concerning and suggests that she may be facing a serious health issue, such as a severe infection, poisoning, or another critical condition.
Firstly, it's crucial to keep her hydrated. Dehydration is a significant risk when a pet is vomiting and has diarrhea. Offer her small amounts of water frequently.
And start with bland, easily digestible options like plain boiled chicken.
However, given the severity and combination of her symptoms, I strongly recommend seeking immediate veterinary care. The green color of her vomit, along with the other symptoms, could indicate a serious underlying issue that requires prompt medical attention.
And did Mocha get all the vaccines? There’s a possibility of Parvo virus. If it’s a parvo virus, there’s nothing you can do at home. You should go to the vet. Parvo virus has very high propagation power. In addition, in the case of young pets, the fatality rate is also somewhat high.
If you have any further questions or need additional assistance, please don't hesitate to reach out. Thank you.
