Noticing lumps or bumps on the skin of dogs or cats

Some pets seem predisposed to skin growths

As pets age it is fairly common for both cats and more commonly dogs to develop various growths, cysts, skin tags and tumors. Some pets seem to be predisposed to multiple skin growths especially as they get older. Most of these growths are noticed by guardians who regularly groom and/or pet their animal companions. The most common type of skin growths noted by guardians are benign warts, cysts or fatty tumors known as lipomas.

Most of the time we don’t know why certain animals are predisposed to such growths, although probably genetic causes, compounded by possibly nutrient poor, processed commercial pet foods, exposure to chemicals and/or pesticides, and over-vaccination probably all play roles. Whenever animal guardians note any growths felt in or under the skin, it is important to bring these to the attention of the small animal veterinarian. The veterinarian will often perform a needle aspirate of the lump, and look at the cells under a microscope to make sure that the growths do not need further surgical biopsy or removal. The needle aspiration procedure will also allow veterinarians to distinguish benign fatty tumors that can often be left alone, from potentially more serious growths, such as mast cell tumors which usually need more aggressive surgical and/or medical care.

While there is a obviously a genetic predisposition to any types of tumors or growths, I strongly recommend that animal guardians feed a healthy diet with food such as Pet Guard or Wysong. I also recommend a good antioxidant multivitamin such as Super Vitachews, as well as adding probiotics/enzymes like NaturVet Enzymes & Probiotics.   And while no animal guardian wants to feel lumpy or bumpy skin growths on their pet, they should not be discouraged or frightened, as long as they have a proper veterinary exam and possible needle aspirate to insure the lumps or bumps do not need further treatment.

  2. Dr. Michael Dym, VMD veterinarianAugust 24, 2011 at 3:31 pm

    The human ointment may or may not help. I would try the homeopathic remedy Thuja in 30c potency from health food store one pellot once daily for 5 days, then wait 3-4 weeks and see if warts go down after 5 day treatment. Also can try topical vitamin E and topical castor oil on them as well a few times daily.

    I think raw diet is ideal with minimal carbs. however I would work with vet homeopath who may be able to help with long term homeopathic prescribing in helping with tumor. To learn more see or my website Many homeopathic vets offer phone consultations.

  6. Dr. Michael Dym, VMD veterinarianNovember 27, 2012 at 1:50 pm

    I would first have your vet check these lumps out to make sure they are only warts. You could try the homeopathic remedy Thuja in 30c potency from the health food store and give 1 pellot once daily for 3 days, and then evaluate over 3-4 weeks to see if any effect on the warts. Sometimes surgery is needed if they bleed or bother the dog.

    I would with a veterinary homeopath on treating the whole patient. To learn more about homeopathy, see as well as my website Many homeopathic vets offer phone consultation. Only traditional medical option is likely surgery.

  9. how can I get rid of fatty lumps on my dog without surgery? Is there any pills my dog can take?

    No real quick fix for this one. You could try working with a veterinary homeopath on individualized constitutional care for your pet. To learn more see

  11. My 9 yr old golden has a number of cyst type bumps on her that occasionally break. We clean the area and apply neosporin. Our vet has advised that they are sebaceous but is Is there something we can to prevent them.

  12. Dr. Michael Dym, VMD veterinarianFebruary 1, 2014 at 4:01 pm

    Nothing specifically to prevent, but I would recommend minimizing vaccinations in pet this age which I think worsens this tendency, and feed an all natural diet like wysong epigen diet from 1800petmeds.

  13. I have a 12 yr old pure breed Siberian Husky. About 3 yrs ago small fatty tumors started developing. Last year I had to remove one of these small fatty tumors that developed into a large 2.6 lb benign fatty tumor.

    What recommendation or solutions are there to reduce or prevent or treat them to remain small.

    HI Mitch. I find that these fatty tumors are a chronic immune response to too many vaccinations given early in life in many cases. I leave them alone unless they interfere with mobility, as these tumors are typically benign. You can have your vet aspirate them to confirm diagnosis. You can also try the homeopathic remedy Thuja in 30C potency from health food store and give 1 pellet once weekly for 4 to 6 weeks only, and see if any changes in the lipomas

  15. My overweight (19-20 pounds), aging (15 years) cat has early stage diabetes, warts on her skin, and soft stools. She has been on metronidizole (1/4 tablet 1x a day) for a couple of months. Warts seem fewer, stools soft not runny, but still heavy urinating, overeating, drinks lots of water. Is there a program that can help her? Perhaps a combination of therapies. Weight loss (wish it were simpler) might mean no meds needed for the diabetes. Gave her high protein Rx diet from vet, and she got watery stools. What a mess! Returned the diet for money back. Rice/lamb seems to works best to calm her bowels, as kibble or soft, but carbs not good for diabetes. Metronidizole seemed good for the warts on her skin. Any suggestions? How long can a cat stay on Metronidizole?

    HI Ina….I would strongly recommend at least an integrative approach here or possibly an all holistic approach. I would get book The NAtural Cat by Anitra Frazier, who is expert nutritionist and a friend of mine. We help many cats across the country on dietary and homeopathic treatment of many chronic diseases. Anitra’s phone number is 212-663-0122. I would also learn more about homeopathy at as well as my website Many homeopathic vets offer phone consultations like myself.

  17. Hello, I have a 12 yr old OES. about a two yrs ago she developed a bump on her back the vet said don.t worry about it unless it gets bigger. It never got any bigger but it burst when she was scratching or playing. It now has that pasty fluid coming out and has dried there. It has a real bad smell. what can I use to clean it Regular dog shampoo and warm water don.t seem to work it has a crust and still oozes alittle It does not seem to bother her though. Thank You

  18. Dr. Michael Dym, VMD veterinarianNovember 4, 2014 at 2:22 pm

    You can try dilute chlorihexidine soap 1:10 in warm water and flush the area. This soap should be available over the counter or you could use dilute betadine as well. BEst to see vet, however for proper exam and evaluation, etc

  19. I have a black long haired cat about 18mts of age, that has small round balls under his chin. They are in groups of 3 or 4. I will rub under his chin so that is how I discovered them. Are the bumps, or lumps like the ones that are described in this article? He’s an indoor cat that I take for walks in the yard area. I do this so he can get some grass on these trips outside. Plus I like walking with him. Good bonding I believe. So any info would help. Thank you very much.

    Best to have vet exam, as could be kitty acne or blackheads under the skin. Vet exam will rule out tumors or growths.

  21. My 8 year old pitbull /lab mix has bumps all over her body. Sometimes she will scratch them till they bleed. Any thoughts on how I can help her?

  22. Dr. Michael Dym, VMD veterinarianJanuary 23, 2015 at 7:43 pm

    Best to have vet exam and evaluation as could be secondary skin infection from likely underlying allergy or hormonal issue in this breed mix. Need this for proper diagnosis and treatment.

  23. I have a eight year old border collie. She suddenly grown a lump on her shoulder. She is a bit over weight but I have been tapering her down slowly. Could it be the food I am giving her? Would changing her diet help any? If so what type of food would be best?

  24. Dr. Michael Dym, VMD veterinarianJanuary 26, 2015 at 5:42 pm

    I prefer all natural low carb, low grain diets like Wysong epigen diet from 1800petmeds. I dont think that in itself will get rid of lump. I would see vet to have lump aspirated for proper diagnosis. Sometimes lumps can be left alone. Othertimes they need to be removed.
