My pitbull mix has a pink hairless bump on the back of his neck. Hes had it since we got him but we recently noticed it seems bigger in size. What could it be?

A hairless pink bump like this that's been present for a long time is likely to be a skin growth or tumor of some kind - it could be either benign or cancerous. I would recommend having the bump checked by a vet when you are able to - he/she can do a simple test called a fine needle aspirate if needed to find out for sure what it is and whether it needs to be removed.
