My puppy is thin, losing hair, and scratching. What should I do now?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Female | spayed | 3 months old

Good day! My puppy, just turned 3 months yesterday, became thinner as i have noticed today. Then, her legs have lost hair and she keeps on scratching. I'm a first-time puppy owner and I don't know what to do :( Her behavior did not change though. She still eats all of her food and she is still playful. I will bring her to a vet clinic near us tomorrow but right now I need advice on what I can do. Please help me I am new at this. Thank you very much.

Thank you for submitting your question regarding Elle. She has lost a fair amount of hair. I am glad that she will see her veterinarian soon. Demodex is a common mite in puppies that results in hairloss. This is identified with skin scrapes. Ringworm can also cause hairloss. It is diagnosed with a fungal culture. Based on these results, medication will likely be prescribed. In the meantime, place an E-collar on her if she is itching or scratching the affected areas. I hope this information helps!
