Here's why:
* Pain: While some discomfort is normal after surgery, thrashing and heavy breathing suggest significant pain.
* Complications: These symptoms could indicate complications like internal bleeding, infection, or a reaction to anesthesia.
What to do:
1. Contact your vet immediately. They are the best resource to determine the cause and recommend the appropriate course of action.
2. Describe the symptoms in detail. This will help the vet assess the situation.
3. Monitor your dog's condition closely. Watch for any other changes in behavior, such as:
* Lethargy
* Loss of appetite
* Vomiting
* Fever
* Discharge from the incision site
Important Note: It is crucial to seek veterinary attention promptly if your dog exhibits these symptoms. Ignoring them could lead to serious health consequences.
