What is mastitis?
Mastitis is a condition of swollen mammary glands in female dogs, which can occur with or lead to infection.
Mastitis typically occurs after a female dog gives birth as a result of an at-home birth site that has not been effectively sanitized or from weening the newborn puppies too early. There are a few different types of mastitis that a dog can develop.
- Acute Mastitis. A swollen mammary gland in dogs, potentially leading to the mother's avoidance of feeding the pups or lethargy.
- Septic Mastitis. Inflammation of the mammary gland that leads to heat, pain, milk discoloration and potential sickness in the mother.
- Non-septic Mastitis: Inflammation of the mammary gland that is not caused by bacterial infection.
- Chronic Mastitis: Swelling of the mammary gland that lasts long-term. This type of mastitis is not as visibly obvious as other types as it does not share their symptoms.
- Gangrenous Mastitis. Blackening of the teat, sometimes accompanied by darker stomach tissue, as well as illness in the mother.
With all of these different types of mastitis, owners of expecting mother dogs may want to know how to identify postpartum mastitis.
What does mastitis look like in dogs?
The symptoms of mastitis in dogs can vary, as some symptoms affecting the mammary glands and teat may or may not cause further signs of sickness in the mother herself. As aforementioned, some types of mastitis will lead to discoloration of the teat or even discoloration and blood in the milk. Here are some common symptoms of mastitis in dogs:
- Swollen mammary gland or teat
- Discoloration of milk/discharge
- Refusal to feed puppies
- Fever in the mother
- Depressive behavior
- Changing blood pressure or heart rate
If you notice any of these symptoms in your postpartum pup, contact your vet immediately.
What are the causes of mastitis in dogs?
There are a few common causes of mastitis in canines that owners of pregnant dogs should know in order to prevent the condition from developing. Some of these causes include:
- Bacterial or fungal infection of the teat or mammary area in pregnant dogs
- Loss of newborn puppies
- Milk clots or backed-up milk
- Unsanitary whelping box
- Damp birth site
How do vets treat mastitis in dogs?
To first diagnose mastitis, your veterinarian will perform a full physical exam, and will sometimes collect necessary information on the mother's pregnancy and labor.
Depending on the severity and type of mastitis your dog contracts, treatment can be in the form of prescribed antibiotics or even surgery. If the mother is still nursing her newborns, the vet will likely also require gently milking the glands until the infection is completely cleared up. Milking the glands will also afford the owner or the vet an opportunity to check on the level of swelling, heat or other conditions of the teat. Mild cold compresses may also be beneficial to help the dog feel a bit more comfortable.
In general, mastitis is usually fairly treatable at home. Consult your vet for best practices with your pup suffering from mastitis.
