Lump or Swelling – Mammary Gland

Urgency level: Possible emergency

Contact an emergency veterinary hospital

What to do next

Contact an emergency animal hospital ASAP and don’t let your dog scratch the affected area

  • Contact the vet before travelling to ensure they are able to see your pet. They may also need to give you specific instructions. Some regular hospitals may be able to treat your pet.
  • Do not feed your dog. The emergency vet will likely need to sedate your dog, and in these cases it is ideal if your dog doesn’t have a full stomach.
  • Don’t let your dog lick/scratch the affected area. Put a cone on her if you have one.


Why it’s an emergency

Your dog is at risk of mastitis, which can be a life-threatening condition

  • Lumps and swellings have a wide range of causes, including insect stings or bites, bruises or strains, fractures, abscesses, and tumors. Your vet may need to examine your dog carefully to determine the exact cause.
  • Hot, swollen and/or sore mammary glands suggest mastitis, which requires immediate veterinary attention. This situation is time sensitive and potentially life threatening. It is most common in dogs that have recently given birth.
