There is a very recent and circular scab like wound on my 7 year old male's back. I will say its a prime spot for scratching. I really want to avoid taking him in, vets can be so expensive, especially when it can just be a little cut that needs healing time. Could we use neosporin on him? Is there a concern is is very serious? The smaller pic is his hair relaxed over the wound area. Please let me know what you think this is. Thank you!
