Usually dog ​​breasts are evenly distributed on both sides of the chest and abdomen, and the color of the nipples ranges from pink to black, which is closely related to the dog's breed, age, color, etc. If the breast becomes inflamed and becomes diseased, fluid will overflow from the nipple, and lumps will form in the breast, the dog needs to be taken to the hospital for treatment immediately. If the dog is pregnant and suddenly finds a lump in the dog's breast that keeps getting bigger, in this case, the owner does not need to panic, because the dog's mammary glands will develop normally due to the influence of hormones such as prolactin at this time.

What to do if your dog has mastitis:

1. After your dog is diagnosed with mastitis, it needs immediate treatment. Broad-spectrum antibiotics can be used, such as cephalexin, amoxicillin, etc.

2. Massage and express the affected breasts several times a day. After expressing the breasts, inject aqueous antibiotics into the milk pool through the nipple duct, 2 to 3 times a day.

3. If medical treatment is ineffective, the only option is to remove the lump surgically.
