We have a 13 year old Husky/Heeler Mix. He has a huge bump on his right side about where his shoulders are, he has had this about 5 months, and he is having more and more trouble walking, now he has started breathing fast and panting at certain times like he is having difficulty breathing. Nothing he does or we do causes him to start panting. It's almost like what he does when he rides in a car.

Poor guy! In a senior dog, I would be very concerned that his huge bump is a malignant tumor that has now spread to his lungs causing his problems with breathing. Cancer can also affect his walking. I would have him seen by a vet right away. This bump needs to be diagnosed with a fine needle aspirate to see if he does have a malignant tumor, and x-rays need to be done of his chest to see his heart and lungs. Once the cause of this bump and difficulty breathing and walking is diagnosed, the vet can discuss if there are any treatment options for him.

I don't see any photos attached to this post so I am not able to see the lump. If the lump is getting bigger than you should have him examined by a vet to determine the cause. Your vet can do a needle aspirate to help diagnose and then your vet can recommend a treatment plan. He may need an antibiotic, anti-inflammatory, or your vet may want to remove the lump.
