She was act by another dog and her right leg is swell up .
I'm truly sorry to hear about your dog's situation. Swelling in the leg following an attack by another dog can be quite concerning, as it might indicate issues such as a bite wound infection, a fracture, or even internal bleeding. Considering her age and existing medical conditions like heart failure, cancer, and diabetes, it's essential to address this promptly.
While you prepare to seek veterinary care, there are a few things you can do at home:
Firstly, try to keep her calm and comfortable. Limiting her movement is important to prevent any further injury, so provide her with a soft and cozy place to rest.
If you can, gently examine the area for any visible wounds, punctures, or bleeding, but be careful not to apply pressure to the swollen area.
If you notice any open wounds, you can gently clean them with saline solution or clean water. It's best to avoid using hydrogen peroxide or alcohol, as these can irritate the tissue.
Applying a cold compress or an ice pack wrapped in a cloth to the swollen area for short periods, about 10-15 minutes, can help reduce swelling.
Additionally, monitor her for other symptoms such as signs of pain, difficulty breathing, or changes in behavior, as these could indicate a more serious issue.
Given the severity of the situation and her pre-existing health conditions, I strongly recommend taking her to a veterinarian immediately. They will be able to conduct a thorough examination and provide the necessary treatment, which may include antibiotics, pain relief, or other interventions.
If you have any further questions or need additional assistance, please feel free to ask. Thank you.
