Hi. I found this on my labradors neck\back today buried in his hair. It looks very infected. I can't believe I missed it. It is about 1.5 cm in diameter. What on earth could it be?

This presentation could be due to a trauma or localised spot of skin infection (likely to be caused by bacteria). A check up, appropriate disinfection and eventually antibiotics (oral, topical or in a shampoo formulation) are needed to solve the problem. Disinfection can eventually be started at home with very diluted hibiscrub or betadine or salted water baths. Buster collar may be useful as well to avoid licking. Please do not hesitate to contact us again on the forum or by requesting a consultation (where you can post pictures) if you have any more questions or to discuss it any further.
