What are these dark brown spots on my dog's tail that I can squeeze?

Updated on September 23rd, 2025

Pet's info: Dog | Cavalier King Charles Spaniel | Male | neutered | 3 years old | 26 lbs

Any thoughts on what this is?? It is in the skin of my dogs tail. If you squeeze each spot something dark brown comes out. I have cut away the fur over it for a clearer view.

It appears that Harley has many blackheads on the skin of this area. What needs to be done with these cases is manual expressing of the skin to help remove the blackheads and also use a shampoo that contains benzoyl peroxide such as Dermabenz, which can be purchased online. I would do this for several weeks and see if you can get the condition under control. If not, then I would have Harley examined by a veterinarian so that the most appropriate treatment recommendations can be made. I hope this helps! I would also recommend supporting the skin with supplements such as Welactin fish oil capsules and essential 6 spot on by Dermoscent. Please let me know if you have any other questions / concerns and I would be more than happy to help you further.
