Female hounds breastfeed like mammalians, their designation deriving from the mammary gland used to manufacture milk. The milk is brimful of nutrition and planned to keep their endangered pups nourished and safeguarded from possible diseases. Sometimes these mammary glands can become inflated, usually looking swollen or red. This breast swelling in dogs is natural as both their heat cycle and gestation can occasion inflammation. But this occurrence can happen because of a primary pathology or an affliction like mastitis. It can also occur on sterilized female dogs who may not have gestation associated causes of the redness and inflammation.
Swollen dog breasts in bitches during heat

If a bitch is licking her bulged genitalia to alleviate the irritation of being in season, she may touch these base two teats as she tries to outreach her vagina. This is particularly the case if the hound is obese and grapples to reach her vulva. The bottom two teats may also be perturbed more than others because of their closeness to the vagina.
