Sign 6: Persistent Lameness
Understanding chronic limping
Chronic limping or lameness, especially when it doesn’t improve with rest, can be a sign of bone cancer. Osteosarcoma is a common type of bone cancer in dogs that can cause severe pain and lameness.
How it can be a cancer symptom
Bone cancer causes pain and inflammation, leading to persistent limping. If your dog is limping for an extended period, a veterinary examination is crucial to rule out cancer.
Sign 7: Unusual Odors
Detecting abnormal smells
Odd smells coming from your dog’s ears, tongue, or other body parts might indicate cancer. These odors can be quite strong and persistent.
Why cancer might cause this
Tumors can become infected or necrotic, leading to bad smells. Oral tumors, in particular, can cause foul breath, while tumors in other areas can cause different unusual odors.
Other Symptoms to Watch For
In addition to the signs mentioned, other symptoms can indicate cancer. These include:
- Chronic vomiting or diarrhea
- Unexplained bleeding or discharge
- General lethargy and fatigue
- Swelling in the abdomen
- Changes in behavior or mood
