* Allergic reaction: Dogs can have allergic reactions to a variety of things, such as food, insect bites, and pollen. Symptoms of an allergic reaction can include swollen eyes, shaking, and difficulty breathing.
* Infection: Bacterial or viral infections can cause a dog's eyes to become swollen and their body to shake.
* Trauma: If your dog has suffered a head injury, it could cause their eyes to swell and their body to shake.
* Neurological disorder: Some neurological disorders, such as epilepsy, can cause a dog's eyes to roll back in their head and their body to shake.
What to do:
If your dog's eyes are swollen almost closed and he is shaking, it is important to take him to the vet immediately. The vet will be able to determine the cause of the problem and provide treatment.
In the meantime, there are a few things you can do to help your dog:
* Keep him calm and quiet. This will help to reduce his stress and prevent him from further injuring himself.
* Apply a cold compress to his eyes. This will help to reduce swelling and pain.
* If your dog is having difficulty breathing, try to clear his airway. You can do this by gently lifting his head and neck and pulling his tongue forward.
It is important to remember that these are just temporary measures. Your dog will need to be seen by a vet as soon as possible.
