My dog has soft, swollen lumps on both hips. Are they tumors or fat?

Thanks for using Petco Pet Education Center, formerly Petcoach! Without seeing Genesis it's hard to say. If the lumps are symmetric and soft, it is likely fatty subcutaneous tissue. Like "love handles" in people. Again, without seeing her I can't say that for sure but this is a common area where fat is stored on dogs and owners commonly are worried about it. The best diagnosis is having a vet stick a needle in it and look at the cells under a microscope. I hope this helps! Kisses to Genesis!

Unknown lumps and bumps are virtually impossible to diagnose without, at the very least, a visual inspection of the area. As such, I will provide you with some general information. An unknown mass or lump is typically one of the following: a cystic (fluid filled) structure, an abscess (fluid-filled, but infected), a mass / tumor, an allergic reaction / insect bite, or the result of a traumatic injury. A thorough physical exam and inspection of the affected area would be needed in order to determine which is most likely. In many instances, a needle aspirate (small amount of fluid obtained from the lesion and placed on a microscope slide) or tissue biopsy would be required to obtain a definitive diagnosis as to the type of lesion. If this is not an option, one must consider the location, distribution, duration of onset, patient breed / age / sex, and a variety of other factors. As Foxy is a younger dog, it is less likely that she would have a malignant tumor on her body than if she was elderly. You mentioned that the lesion is soft - this is typically a good sign that she is dealing with something benign or harmless. Whether or not this mass has anything to do with the weight loss is very difficult to say. I would recommend you make a regular appointment to see your vet and have her assessed as a whole. Hope this makes sense.

This looks like a tumor. You need to make an appointment with your veterinarian to have this mass examined and preferably have a Fine Needle Aspirate done to send to a laboratory or have it removed right away if possible, in case it is a malignant growth. The FNA will help with diagnosing whether this is malignant or benign.

These lumps needs to be checked and analysed as there are many conditions and types of tumors that could look like that. take him to the vet, they will perform a fine needle aspiration on the growths and send it to the lab for analysis. when the result comes, the vet will advise what needs to be done according to the diagnosis.

I think the area you're talking about is right below the hip bones. That wouldn't be a bone there (if I'm understanding where you're indicating), but could be a muscle or fatty area. Since it's similar on both sides and he's walking normally, it's most likely normal. However, if you're seeing the right side get larger, I would definitely schedule a vet appointment to have the area evaluation and probably sampled with a needle or possible x-rayed. I hope the helps you decide how to proceed.

Its difficult to tell without being able to directly palpate (feel/touch/examine) the area, but I suspect its probably just how fat has deposited there. Its common to have a fat "pooch" in that area, usually it will be about the same size on both sides of the abdomen. If he's not painful, he's acting normally, and it looks the same on both sides, you don't need to be concerned about this. Thanks for asking Petco Pet Education Center, formerly Petcoach!

It is difficult to determine the cause without examining the dog. It could just be normal anatomy or it could be a mass or cyst. Have your vet take a look at it to help diagnose. If needed, your vet can aspirate it and examine the cells under a microscope.
