Found lumps on my dog's back. Are they fleas/ticks? What should I do?
Updated On September 23rd, 2025
Hi my dog is a 10 year old caviller King Charles spaniel. Today I found has 3 lumps on her back. They are tiny and like on the surface of the skin but one of them (the first photo) appears to be bigger under the skin which I can feel through her skin but not see. I am planning to take her to the vets on Wednesday if need be as that is when I get paid but I was wondering if it was ticks/ fleas/ lice etc. incase I can buy a treatment over the counter and start treating it before Wednesday.

I can't really tell from the picture what it is. If you dog isn't on a flea or tick preventative, that could be part of the issue. Skin infection, sebaceous cyst, or other masses would be possible, as well. I would wait and see what happens. You can get her started on a flea preventative, and use a medicated shampoo like Dechra MalAcetic Ultra Shampoo for mild skin infections.

These look like either cysts or a skin infection but I cannot say for sure without seeing her in person. Cysts aren't usually painful but may bother her a little. Skin infections can be itchy but not always. Skin infections are commonly secondary to allergies. You may want to try to put her on benadryl twice a day and bathe her in a medicated shampoo like miconahex-triz shampoo. If this doesn't help, she gets worse or she seems painful, I would have your vet take a look at them . Your vet will be able to determine the cause and the best treatment for her if needed.

She could have an infection or an allergic dermatitis. If you can't take her to a vet than you could bathe her with a dog shampoo, like Epi-soothe and see if that helps. If not, she needs to be seen by a vet as she may need an antibiotic, anti-histamine, and/or a corticosteroid to treat.

It could be a cyst or a small pustule. You could bathe her with a shampoo like Duoxo Calm and see if that helps. Otherwise, have your vet take a look at it so see if she needs treatment or if it should be removed. She may need an antibiotic or anti-inflammatory to help.
