Hello doctor. Recently on last weekend my dog got his yearly rabies and parvo shots and by the next morning I started to feel a lump on the side of his body. And this is not the place where the shots were given. I'm really very tense and want to know what is this?

I would be pretty concerned, As this is pretty big if it has just grown in a week. I would highly encourage you to have him evaluated by your veterinarian soon. This could be an infection, a benign tumor, or even a cancerous tumor. The faster you can find out what it is the more likely it is to be solved. Best of luck and I hope he improves soon! Thank you for using Pet Coach.
