My dog is losing weight, has lumps, and dark pee. Should I worry?

So sorry she is having these problems. Drinking and urinating more can be a sign of kidney disease, Cushing's disease, diabetes, Addison's disease, infections, thyroid disease, etc. The only way to know the cause is to have a vet run some bloodwork and a urinalysis. The lump could be a cyst, infection, benign or cancerous mass. A needle aspirate or biopsy may be necessary to diagnose. She really needs to be examined by a vet. Try to find a low cost clinic in your area or a vet that would take a payment plan. You could also apply for Care Credit which is a veterinary credit care. Hope you can find her the help that she needs.

Please have her checked by your vet as soon as possible. This is not normal and although any lumps are concerning, any that are painful or rapidly growing are very suspicious for underlying issues such as cancer. Early diagnosis and treatment is vital to improve outcomes and reduce undue pain and discomfort.

Weight loss can be caused by many problems. A few of these include parasites, diabetes, kidney disease, and cancer. I would certainly be worried about the lump on her side and whether or not it is associated with why she is losing weight. I would encourage you to have her evaluated by your veterinarian as soon as possible. They will likely recommend blood work to help determine why she is losing weight as well as sample the lump to find out if it is anything concerning. Best of luck and I hope she improves soon. Thank you for using Pet Coach.

It does sound like Pepper is sick. This large lump on her side could be an abscess, cyst, benign tumor, or a malignant tumor. An abscess or malignant tumor would cause her to not want to eat or drink. It is serious that she doesn't want to drink, and I would take her into a vet now. If you wait until morning, she could become seriously dehydrated, and it's best to prevent that. The vet can examine the lump and can perform a test called a fine needle aspirate on it to diagnose 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. The vet will also likely do routine blood tests and a urinalysis to diagnose why she is feeling so poorly, and how best to treat her.

The lumps needs to be checked and analysed as there are many conditions and types of tumors that could look like that. take her to the vet, they will perform a fine needle aspiration on the growth 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.

Thanks for using Petco Pet Education Center, formerly Petcoach! Blood in the urine can be observed with things like urinary tract infections, urinary tract stones and even urinary tract tumors. The masses under the skin can be due to a benign or malignant growth. Both of these conditions can be linked or be completely separate issues. A urinalysis and urine culture can be performed to check the urine. Abdominal imaging may also be recommended. The lumps could be benign or malignant growths. This is often differentiated by a test called a fine needle aspirate (FNA) which is a pain free, inexpensive and easy procedure which in most cases will help reach a diagnosis. Sometimes a biopsy is needed for a definitive diagnosis. I recommend that you have her evaluated by your veterinarian for further assessment and treatment. I am really hoping for something benign. Good luck and have a good night!

As for the bump, my biggest concern would be an enlarged lymph node and mammary cancer. The black stool, lethargy, and thirst are suggestive of bleeding in the intestines. Since she is not spayed, a pyometra would also be a possibility. You need to get her to a veterinarian as soon as possible for bloodwork and abdominal x-rays or ultrasound.
