Behaviours that might indicate your dog is uncomfortable include:
Loss of muscle
Unsettled at rest, including frequent changes in position and pacing
Increased sleep and withdrawal from favourite activities.
Weak hind end / difficulty rising
Most dogs do not whine in pain. If they are whining, typically, they are in a lot of pain!
Most pain can be reduced or eliminated with proper care. With training in animal acupuncture and having completed my advanced animal chiropractic education, I have many tools to help improve function and reduce pain.
