Rhodesian Ridgebacks have an increased risk to develop benign prostatic hyperplasia.

Benign prostatic hyperplasia (BPH) is an age-dependent primarily non-inflammatory enlargement of the accessory gland in the intact dog. The aim of the present study was to control a previously raised suspicion of a breed-related higher incidence of BPH in dogs of the Rhodesian Ridgeback breed. For this, 18 Labrador Retrievers/LR and 20 Rhodesian Ridgebacks/RR were assigned to the age groups 18-24 months (n = 12), 25-48 months (n = 13) and 49-72 months (n = 13).

Impaired spermatogenesis, tubular wall disruption, altered blood-testis barrier composition and intratubular lymphocytes in an infertile Beagle dog - a putative case of autoimmune orchitis.

Impairment of blood-testis barrier integrity can be observed during inflammation, infection, trauma and experimental autoimmune orchitis, which is inducible in rodents. In the present study, an initially fertile two-year-old Beagle dog was presented with a decline in total sperm number resulting in azoospermia within five months, verified by twice-monthly semen analyses. The dog was clinically healthy with bilateral small testes and showed normal thyroid function.

Proliferative and apoptotic changes in the healthy canine endometrium and in cystic endometrial hyperplasia.

Proliferation and apoptosis play an important role in cyclic changes in the healthy canine endometrium. Proteins of the Bcl-2-family are known to be involved in the regulation of apoptosis. However, only few reports mention their expression patterns during cystic endometrial hyperplasia (CEH).

Monochorial diamniotic dizygotic twins in a German Shepherd Dog: A case report.

A 6.5-year-old clinically healthy German Shepherd Dog with regular oestrous cycles of 6 months was presented for pregnancy diagnosis on day 38 after ovulation (p.ov.

[Evaluation of the blood progesterone concentration in the bitch measured by chemiluminescence immunoassay at the day of ovulation].

Objective: Modifications of human test systems used in veterinary laboratory practice could lead to reference-range adaptions for their veterinary use. In 2012 the manufacturer of a widely used chemiluminescence immunoassay modified the test for progesterone measurement leading to a reference range adaption for the breeding-time detection in the bitch.

Material And Methods: The aim of the present study was to evaluate the mean progesterone concentration by using the modified chemiluminescence immunoassay at the time of ovulation in the bitch and to compare this with previously used reference ranges.
