Your assessment results for:

Lump or Swelling – Mammary Gland

Urgency level: High priority

Contact your regular veterinary hospital

What to do next

Contact your regular animal hospital ASAP and don’t let your dog irritate the area

  • If your regular veterinary hospital is open, contact them now. If they are closed, it is probably safe to wait until morning.
  • Monitor your dog carefully – if your dog becomes very lethargic, painful, or vomits, contact an emergency veterinary clinic.
  • Be careful when handling your dog – the affected area is likely painful and they may bite.
  • Don’t let your dog rub/scratch at the affected area. Put a cone on her if you have one.


Why it’s high priority

Your dog is at risk of mastitis, which needs to be treated by a veterinarian

  • 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.
  • Based on the signs you’ve selected, we are concerned your dog may have early stage mastitis which requires veterinary attention as soon as possible. It is most common in dogs that have recently given birth.


Home care tips

Keep your dog calm and monitor the lump or swelling
