Abstract

In this case, pre/postoperatively
clinical and laboratory findings at the case of swelling of a long time mammary glands
in
22 month old Labrador Retriever breed bitch were presented Veterinary Faculty
Animal Hospital. In the anamnesis, it was learned that the size of the mammary
glands although it has been four months since oestrus symptoms and that
aglepriston was used to stay pregnant and terminate the pregnancy in the
previous oestrus. Physical examination revealed that the mammary glands were hyperplasic
from cranial to caudal and increased to normal. Palpation showed that the
mammary glands had a soft consistency and milk came from the mammary gland. Mammary
gland ultrasonography and lung radiography showed no pathological condition. Blood
serum prolactin and progesterone measurements were recorded. According to the
clinical and laboratory findings; it was diagnosed as pseudopregnancy and
treated with cabergoline and daisy tea. Repeated enlargements of the mammary
gland were observed in the same manner and durations during the sexual cycle
follow-ups performed for one year. No macroscopic mass or adverse condition was
observed in mammary glands during treatment and follow-up. In conclusion,
aglepriston, one of the exogenous agents used to terminate pregnancy at an
early age before complete sitting of hormonal development; Dogs caused
irregularities in their sexual cycles throughout their lives, suggesting that
suspected hormonal balance may predispose to various disorders in the future.
