My senior dog has new lumps, ear wax, and dry skin. What's wrong?

Aw poor Tottie! Without examining the lump is impossible to say if it is anything to be worried about. It also sounds like Tottie has an ear infection. I'd recommend taking Tottie to see your veterinarian so that her ears can be checked. Your vet can also check the lump and take a needle sample to determine if it is a problem. Thanks for using Petco Pet Education Center, formerly Petcoach and I hope Tottie's issues can be resolved quickly!

It is hard to tell without seeing it in person, but pimple like bumps often indicate an infection like a pyoderma. Sometimes medicated shampoo can be enough to get rid of the bumps, but other times they need oral antibiotics. I would recommend making sure he is on a good flea prevention and speaking with your vet about the possibility of a skin infection. I hope this helps!

This lump on Johnstamos (LOVE his name!) could be a cyst, a benign tumor, or a malignant tumor. Because it has tripled in size, that does make it concerning. 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 its cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. Once the cause of the lump is diagnosed, the vet can discuss treatment options if needed. As for the scabby and crusty ears, those could be due to an ear infection or allergies. Give his vet a call to make him an appointment to have both these things checked out. I hope this helps!

Thanks for using Petco Pet Education Center, formerly Petcoach! In theory this could be a growth but in reality that is unlikely just based on the size and general appearance. I would encourage you to check in with your veterinarian to check for this possibility so that therapy can be used accordingly. If it is just an infection, your veterinarian may put her on an anti-microbial shampoo. Best of luck!

Thanks for using Petco Pet Education Center, formerly Petcoach! These 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 him evaluated by your veterinarian for further assessment and treatment. Since he has not been drinking well, they would also be able to check if something else is also affecting him by checking into other possible concurrent issues such as gastroenteritis or pancreatitis for instance. I am really hoping for something benign. Good luck and best wishes!

I would guess that these are sebaceous adenomas or benign skin growths that are common in older dogs. There are some other skin tumors that could look similar however and it would be best to have your veterinarian examine Linguine in person to be 100% sure.

Boomer's coat changes could be related to underlying endocrine/metabolic disorders (hypothyroidism or Cushing's disease), allergies, seborrhea, among others. Watch closely to determine if you have noticed any changes in Boomer's water consumption, urine frequency and volume, appetite and energy level. Any of these changes can help your vet determine if he has an underlying condition. Boomer should see his vet for an exam and possible blood and skin testing to determine the cause of his changes so that appropriate treatment can be started.
