I noticed last night that he was pawing at his face. The sides of his mouth have swollen bumps. He's drinking a lot of water and then throwing it up. He is not interested in food. He's just not acting right.
I'm sorry to hear that your dog is experiencing these troubling symptoms. The vomiting, loss of appetite, sneezing, itching, and swollen bumps around the mouth could suggest an allergic reaction or possibly an infection. The clear, liquid vomiting after drinking water might also point to some gastrointestinal irritation.
Let's consider a few possibilities:
Firstly, the swelling and itching could indeed be signs of an allergic reaction. It might be helpful to think about any recent changes in your dog's environment, diet, or exposure to new substances that could have triggered this.
Secondly, the bumps and other symptoms could indicate an infection, which might be dental or skin-related.
In terms of hydration, it's crucial to ensure your dog stays hydrated. If he continues to vomit after drinking, try offering small amounts of water frequently instead of allowing him to drink large quantities at once.
Regarding his diet, since he's not interested in food, you might consider offering bland foods like boiled chicken and rice, but only if he can keep it down without vomiting.
Given the combination of these symptoms and their persistence, I strongly recommend consulting a veterinarian as soon as possible. They can conduct a thorough examination and provide the appropriate treatment, especially if an allergic reaction or infection is involved.
If you have any more questions or need further assistance, please feel free to ask. Thank you.
