My dog's anus is black after boarding. Is this normal or serious?

Thanks for using Petco Pet Education Center, formerly Petcoach! This is unlikely to be something of concern and most likely represents a region of pigmentation. However, I recommend you keep a close eye on it and if at some point it appears to become a mass, have him evaluated by a veterinarian for further assessment. Good luck and have a good night!

Hi there and thanks for posting. Certain shampoos or sprays may irritate the skin and anus especially if she has a history of sensitive skin. Sometimes the groomers will express the anal glands as part of their grooming routine. If that was the case, sometimes there can be a small amount of inflammation afterwards especially if the anal sacs were very full. She may also have a skin infection or infection of the anal sacs as well which may be unrelated to the grooming. Feel free to send along pictures or you can also request a consult with me to share pictures and I can provide additional feedback. I hope this helps!

The changes in skin color can be normal base on the environemtn but may be a sign of yeast infection on the skin also. If it has an odor, is oily, or itches her then that is a sign it may be a yeast infection and she will needed to be treated. If she is normal with no signs noted, then you can monitor the area

Poor Willow! Some dogs can experience pigment changes over time or with chronic inflammation. It's quite possible that the darkening of Willow's anus is a relatively normal change. As you've mentioned, scooting commonly occurs with full anal glands. I'm glad that you have a vet appointment scheduled for her. Your vet will be able to perform a rectal exam to be sure that everything feels normal, as well as empty her anal glands. It should be ok to wait 2 days since that's the next appointment. Full anal glands certainly aren't an emergency, but sometimes the anal glands can become impacted, infected or rupture, which would be a more urgent problem. If you notice any significant swelling or redness on her hind end, I would try to have her checked out sooner. I suppose that it's possible that she could have a perianal fistula, but these occur most commonly in intact male dogs and are often quite red and oozy. It's far more likely that her anal glands are simply bothering her. I hope that all goes well for Willow!

This is pretty normal. I wouldn't worry unless you notice excessive licking of the area or scooting which could mean anal glands are clogged. That would require expressing from a professional groomer or veterinarian.

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your question. Based on the picture, I see nothing concerning other than a darker colored area. If you are seeing diarrhea, worms, a rash, etc. I would recommend having this looked at by a veterinarian so that the most appropriate diagnostic and treatment recommendations can be made.

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. What you are describing could be secondary to a bacterial / yeast infection or allergies. I would recommend using the below products to see if the black discoloration resolves. If the discoloration is still present and Duke continues to lick the area or it worsens, I would recommend discussing allergy medication options with your veterinarian such as Apoquel and Cytopoint. A veterinary dermatologist may also prove to be helpful in figuring out what the main problem is. I hope this helps guide you in the right direction. Please let me know if you have any other questions or concerns and I would be more than happy to help you further. 1.
