Thank you for submitting your question regarding your dog. Depending on the age and breed of your dog, it will make certain things more likely. For example, small breed dogs are prone to neck and back pain. This can come on suddenly and be excruciatingly painful. Large breed dogs tend to experience joint pain as they age. Puppies are more likely to experience pain as a result of trauma. Older dogs can have an internal illness that will make them pant and potentially drink more water. I recommend that your dog sees a veterinarian if the symptoms are persisting. Do not give any over-the-counter pain medication as these can be toxic to dogs. I hope this information helps!
