My 7 month old black lab has a growth by his ear that seems to be getting considerably larger everyday. He has this growth for about a week.

Thanks for using Petco Pet Education Center, formerly Petcoach! This could be a benign or malignant growth. There is no way of knowing for sure without an examination though this represents a reason to seek veterinary care. This is usually determined with an examination and a fine needle aspirate (FNA) or a biopsy. Treatment depends on the findings up to that point. I recommend you have Clark evaluated by a veterinarian for further assessment and treatment. Good luck and have a good night!
