What should you know about nasal squamous cell carcinoma dog?

Squamous cell carcinoma begins in squamous cells and may form a firm, crusted, ulcerated, or bleeding lesion on the nose. Similar-looking changes can result from infection, inflammation, trauma, or another growth, so appearance alone cannot establish the diagnosis. A veterinarian may inspect the nose and nearby tissues, check lymph nodes, and recommend a biopsy. Imaging may be used when the lesion is extensive or deeper involvement is a concern. The veterinary team can explain what the findings mean for your dog.

Book a veterinary appointment promptly and prevent rubbing or scratching if possible. Do not use human wart, steroid, or cancer creams on the nose unless a veterinarian specifically prescribes them. Bring a list of medicines and note changes in appetite, breathing, bleeding, activity, or lesion size. Depending on the biopsy and location, options may include Surgical Excision, Mohs Surgery, or broader Skin Cancer Surgery. Treatment planning should balance tumour control with comfort and nasal function.

Seek urgent veterinary care for uncontrolled bleeding, laboured or noisy breathing, marked facial swelling, severe pain, collapse, or inability to eat or drink. A lesion that repeatedly bleeds, grows, becomes an open sore, or causes persistent nasal discharge also deserves prompt review even if your dog otherwise seems well.

What other causes could resemble this lesion? Is a biopsy needed, and how will it be performed? Has the tumour affected deeper tissue or nearby lymph nodes? Which treatment best protects comfort and breathing? What wound care and warning signs should I expect at home?
