Why is my dog lethargic with yellow skin sores and a fluid lump?

Hello! Those lesions could be caused by an infection like bacteria or even fungus as well as allergies. Usually though mild infections and allergies don't cause dogs to be depressed/act abnormally. If his behavior continues, he has any vomiting, or his food/water intake goes down further I recommend having your veterinarian do an exam as those changes could be caused by something more serious, like liver issues, anemia, an infection or even cancer.

Hi, and thanks for your question. This lump/bump/growth should be ideally examined by your local vet to have a diagnosis established. Your vet may want to perform an FNA (fine needle aspiration) or a biopsy to sample the bump and determine its underlying nature. Differentials would include skin cysts, infections, benign or more malignant type of tumors. Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further. If this answer was helpful please let us know, this will be used to improve our service!

Hi Seth! Molly is a lovely looking girl. This pustule could be from an insect bite, it could be a cyst, or she could have injured herself causing it. It is concerning that she is acting lethargic lately, and I would have her seen by a vet first thing in the morning for it as long as she is still eating and drinking, and going to the bathroom normally. The vet can diagnose what is causing this pustule and lethargy, and can treat her for it. If she isn't eating or drinking, is extremely lethargic, or develops other signs such as vomiting and diarrhea, I would take her into a vet immediately. I hope this helps!

Hello and welcome to Petco Pet Education Center, formerly Petcoach. I am sorry Champ isn't feeling well. Lethargy, trouble walking, not eating/pooping are all signs of weakness and being generally unwell. This can be due to many causes however for a dog that is 2 years old I would be concerned about things such as fungal disease, parasite disease, heartworm, Addison's disease, or sometimes it can be more simple like an abscess. The wheezing is concerning that he has trouble in his lungs or heart, so heartworm is a concern. The squishy lump could be an abscess (pus filled pocket) and this could cause all the signs you are seeing as well. Either way, I recommend you get him to a vet right away, even a simple thing such as an abscess, which is fixed fairly easily, can be fatal if not treated in time. Best of luck with Champ! I hope he feels better soon!

This lump on Siu q could be a benign tumor, a cyst, an abscess, or a lipoma. It would be rare for such a young dog to have a malignant tumor, but it is possible. Any suspicious lumps should be examined by the vet. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of it's cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. I would take Siu q into the vet today or tomorrow to have this lump examined and diagnosed so it can be treated as needed. As for the lack of appetite and lethargy, those are very general signs of illness in dogs, and it could be caused by systemic illness, infection, inflammation, or injury. Because Siu q is going to see the vet for this lump, I would have a health check done on her as well to diagnose the cause of the lethargy and lack of appetite.

If there is pus coming out of it, I would be inclined to think that this bump on Bear is an abscess. It would cause him pain, and also cause him to be lethargy. I would take him into a vet either now or first thing in the morning to have this bump examined. If it is an abscess, it will need to be drained and flushed sterilely, and he will need antibiotics to treat the infection.

When there is pus there is generally an infection. Try to clean the area with mild soap and water and flush out the prepuce as this can help. With sore legs and no appetite I would worry about arthritis either from age/injury or an immune mediated or tick borne disease. It is best to take him to the vet so they can do lab work to get you a definitive answer and start IV fluids if needed for dehydration. You can try pedialyte or Gatorade or boiled chicken and rice or yogurt or baby food to help until you can get him seen
