Am J Vet Res 44:1506, 1983. Reports on a radiographic study for pregnancy diagnosis in 6 pregnant Beagle bitches providing basic information for timing and evaluating radiographs during the last trimester of canine pregnancy.

Okkens AC, Dieleman SJ, Kooistra HS, et al: Plasma concentrations of prolactin in overtly pseudopregnant Afghan hounds and the effect of metergoline. J Reprod Fertil Suppl 51:295,1997. Reports on the high plasma concentrations of prolactin and its association with the development and maintenance of pseudopregnancy and the use of metergoline, a serotonin antagonist, to decrease the clinical signs of pseudopregnancy.
Steinetz BG, Goldsmith LT, Harvey HJ, et al: Serum relaxin and progesterone concentrations in pregnant, pseudopregnant, and ovariectomized, progestin treated pregnant bitches: Detection of relaxin as a marker of pregnancy. Am J Vet Res 50:68,1989. In this report it is proposed that in bitches both the ovary and placenta secrete relaxin during pregnancy based on hormone sampling of 18 Labrador retrievers.
Thatcher MJ, Shille VM, Buhi WC, et al: Canine conceptus appearance and de novo protein synthesis in relation to the time of implantation. Theriogenology 41:1679, 1994. Report on secretory proteins: canine protein 1 (cP1), cP2, cP4, and cP6 synthesized by the endometrium and de novo by the conceptus.
