Get Your Dog Care Questions Answered by Experts
Hello and thanks for trusting me to help you and your pet today. I am a licensed veterinarian with over 25 years experience and would be happy work with you but need a bit more information in order to better assist you if you don't mind.
Are the lumps symmetrical (in the same place on both sides?
How large are the lumps?
Do they look inflammed at all?
Would you be able to attach a picture of one or both of them?
Thank you for the reply. I am thinking that you are referring to the dermal papilla from which the whiskers on the muzzle grow. Sometimes they are even clumps of smaller whiskers versus a single one. These would definitely be in a similar location on both sides of the lower jaw and they are not always readily apparent and may become more prominent as the dog grows. They can also become irritated of even infected, but in that case, would usually be red or inflammed.
Another possibility would be a folliculitis which is an infected hair follicle. These are common in young dogs and are similar for comparison purposes to acne in teens. These are usually red and inflammed looking and wold be coincidental to be symmetrically located.
When you get home, take at look at them again and see if there appear to be whiskers, even small ones, erupting from them. If so, they most likely are a normal anatomical structure. If not, I would have your vet evaluate them to make sure they are not infected follicle. I would also have a skin scraping for demodex mites performed as well as they are commonly found on young dogs, living in the hair follicle of the muzzle and causing a folliculitis.
I hope this is helpful. Please let me know if you have ANY other questions. My goal is to give you 100% satisfaction and if you are not yet satisfied, please reply so I can clarify for you.
Sorry for the delay, I was replying to another question. Yes, did get it. Let me review it and respond.
While it does look like there may be small whiskers erupting from that area, this is not what a typical dermal papilla looks like or even an inflammed one for that matter. That is very suspicious of demodex mites and I would definitely have a skin scraping performed. In addition, a ringworm culture (which is a fungus) and a skin cytology to look at the surface cells for bacteria or yeast should be performed as well. It does look symmetrical, but it may be that she is rubbing her chin and creating the hair loss or it is coincidental.

You are most welcome. Please let me know what is found.
