Possible cancer

my dog had a swollen leg and has been to vet twice they said everything is normal but someone mentioned possible mass in this X-ray between spine and colon. Does anyone see it?

Hello - The disaprity in leg shape and size does not look normal on the patient and I wonder whether your vet really meant to imply that your dog is normal?  'Do you think my dog is normal?' could be a good question to clear this up.  We are more about handling communications and less about evaluating radiographs on this page - we do not give second opinions.  However, if you have had conflicting advice then you could ask your vet to refer you for a second opinion.  Who read the radiograph a second time for you? - perhaps you could show your own vet the concerns that were raised, and ask them about it.  Other good questions might include:  what do you think could be causing this problem with my dog?  What has been ruled out?   What can't be ruled out?  What is the next step?

It's better to consult with another veterinarian or a veterinary specialist in your area.
