Why does my dog have bloody, puss-filled lumps and hair loss?

It could be an infection, cyst, or possibly a hystiocytoma. The best thing would be to have a vet take a look at the lesion. Your vet can do a needle aspirate to help diagnose and then determine the best way to treat. He may need an antibiotic, anti-inflammatory, or it may need to be removed. Hope he feels better soon!

This sounds like an abscess or pocket of infection. She may have something in the paw that caused this or it may be from an injury. I recommend a veterinary exam and she will probably need antibiotics. They will check it to see if they can find the cause so it doesn’t happen again. As she’s young I would have this checked right away. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Luna.

This could be a sign of puppy pyoderma, trauma (is she licking the area a lot?), insect bites, or signs of a viral infection/fever, rodenticide ingestion, a congenital or acquired disorder affecting the platelet's ability to adhere to damaged blood vessels. If these blood "blisters" keep enlarging or do not go away within a few days, you will need to consult your veterinarian. The vet will perform a thorough physical examination. Lab tests will be necessary such as a complete blood count, biochemistry profile, and urinalysis and possibly a coagulation panel. There is no specific treatment for those blood filled skin lesions, however it is important to find the underlying cause, which then can be addressed. So, I suggest you monitor the skin and if the lesions enlarge, or if they do not go away within a few days or spread, you take your puppy to your veterinarian. If your puppy gets pale gums it is an emergency and your pup needs to be seen at an ER right away.

I would recommend having Tallulah examined by a vet. The wounds in the picture look like they may be infected. Her skin disease could be caused by a deep bacterial or fungal infection, autoimmune disease, allergies, parasites, etc. The vet may need to treat the infection first to be able to determine what is the cause at a later vet appointment.

It sounds like Harley has some sort of infection in his skin. Abscesses, infected cysts, reactions to something stuck in his skin (like a thorn) and less likely some sort of tumor are all possible. Clean the area with soap and water and rinse it well. Then plan on making an appointment at the veterinarians office to have it evaluated. Make sure he cannot lick or scratch that area as this will cause further damage. The doctor will likely put him on an antibiotic and send you home with an appointment or special shampoo. Hope this helps.

I would be concerned that this growth is an abscess, and the white stuff is pus. I would have Lola seen by a vet for this. The vet can diagnose if she does have an abscess, which will require draining and flushing, and then antibiotics to treat the infection.

Hi Maisie! If there is some pus coming out of it, this lump could be an abscess on Mika. It could also be due to a bacterial skin infection. I would have Mika seen by a vet tomorrow or first thing on Monday to have the lump examined and diagnosed. Once a diagnosis is found, the vet can discuss treatment with you.
