My dog is losing weight, hair, and has a lump. What could it be?

Updated on September 23rd, 2025

Pet's info: Dog | German Shepherd | Female | unspayed | 1 year and 1 month old

Hey dr, my dog Lexy has been losing weight for a while and now she became thin not similar to any female dog her age. I have also noticed a lump high on her arm and she has been losing a lot of hair. What is her problem?

Parasites, cancer, malabsorption or metabolic disorders can all lead to dogs loosing weight and hair. GSD can be prone to pancreatic insufficeincy that can affect absorption of nutrients. I would recomend a vet visit for an medical assessment and also evaluate the lump on her arm.
