Behavioral changes after surgery: What is normal?
Many owners are unsettled when their dog seems changed after surgery: tired, clingier, more anxious, or irritable. It is important to know: Temporary behavioral changes in dogs after surgery are in most cases part of the normal recovery after surgery in dogs.
Expert assessment: "Approximately 80% of all dogs show temporary behavioral changes after surgery. This is a normal part of the healing process and in most cases no cause for concern." – Dr. med. vet. Sarah Schmidt
After an operation, your dog goes through various phases of recovery. Different behaviors may occur:
Immediately after surgery (Days 1–3)
- Fatigue and sleepiness: Completely normal due to anesthesia and medication
- Loss of appetite: Can last 24–48 hours
- Disorientation: After-effects of anesthesia, your dog appears confused or "out of it"
First week after surgery
-
Changed social behavior:
- Increased need for rest
- Possibly more distant from other dogs
- Increased attachment to humans
-
Digestive changes:
- Changed stool consistency
- More frequent or less frequent urination
The 7 most common reasons for behavioral changes after surgery
To better understand why your dog seems changed after surgery, it helps to know the most common causes. This way you can distinguish what is still normal and when you should act.

As experts in dog nutrition, we know: The time after an operation is particularly sensitive. Understand the reasons for behavioral changes in dogs after surgery to be able to optimally support your dog.

Anesthesia can still have an effect for up to 48 hours and lead to the following symptoms:
