Why does my dog's skin tag have a clear fluid-filled bubble?

I am sorry to hear about Zoe. I would definitely recommend bringing her in to the vet to have this growth examined. If it is refilling with blood quickly it would be best to remove the growth surgically because we would be concerned there could be a large blood vessel associated with it and trauma could cause it to break open and have excessive bleeding. We would also want to be sure this is not a more serious growth than a skin tag because there are some more aggressive tumors of the skin such as cutaneous hemangiosarcoma that need to be treated more aggressively.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Thanks for the pictures! Some benign skin bumps, especially sebaceous adenomas can produce discharge. If the bump has been oozing puss and blood it is best to have your Vet re-evaluate it to either: 1) shave the fur, clean it and provide antibiotics or 2) discuss removing it since it has changed and now may continue to be a source of irritation and infection for Cooper. I hope this helps and I wish you and Cooper the best!

Hello, The redness associated with the skin tag could be trauma but I would advise you to take a picture and monitor the area for swelling, discharge or increase in size. If you notice any changes, have Chloe examined and discuss aspirating (sticking a needle into the tissue to remove cells) the area to rule out infection or cancer.

Since it has bled and the skin looks broken, she is at risk for infection. Symptoms may include fever, lethargy, discharge, odor and/or swelling. Ideally, she should be physically examined by your veterinarian. Antibiotics may be dispensed after the exam. Place an e-collar (cone) on Jackson if she is licking the area. Use a diluted solution of betadine or Hibiclens (chlorhexidine) to keep the area clean.

Hello, & thank you for using Petco Pet Education Center, formerly Petcoach. It is always a good idea to seek a hands on veterinary visit, especially as a dog ages & new questions about health arise. Based on your pictures, it is possible that the discolored areas are indeed a reaction to the heat rash. Dog skin will often respond with the production of dark pigments ( melanin ) especially when a condition becomes chronic. As long as the area is not showing signs of a moist dermatitis & there is no significant redness or inflammation, then you can continue to treat the area topically. Skin tags are a common benign polyp, again fairly common as dogs age. The discharge also is probably a benign & normal accumulation of secretions. If each or any of the above become more concerning, then it really is in Nemo's best interest to have things thoroughly looked at & dealt with early on. Take care.

It is difficult to know without seeing the lesion. The best thing would be to have your vet take a look at it to determine if treatment is needed. It could be an infection, cyst, papilloma, skin tag, or a mass. Your vet can do a needle aspirate, if needed, to help diagnose and then determine the best way to treat. It may need to be removed.

It may be that the mass has been injured or become infected. I would recommend to wash it with antibacterial soap daily and you can apply a topical antibiotic. I would still recommend to get Roscoe to the vet as early as you can. The doctor may recommend to have the mass removed and tested. Please post again with any future questions and I hope this helps!
