RESEARCH ARTICLEThe most commonest complaint in animalswith prostatic disease was constipation (66.7 percent) which has also been reported by Hornbuckleand co-workers (1978), Davidson (2003), Kutzlerand Yeager (2005) and Holt (2007) who stated thatconstipation characterized by tenesmus is one ofthe prominent clinical sign of prostatic disease inaged dogs, due to compression of the colon by theenlarged prostate gland. Hemorrhagic prepucialdischarge and dysuria were the observed in 46.7 percent each in the affected animals which has alsobeen reported in earlier studies (Hoeffer, 1977;Read and Bryden, 1995). Dilated prostatic urethralveins are considered to be the source ofhemorrhagic urethral discharge and the inwardgrowth of the gland into the urethra results inDysuria (Reihmann and Bruskewitz, 1993). Otherclinical signs observed in this study were abnormalgait (40 per cent) and loss of body condition (33.3per cent) which has also been described by Johnsonand Archibald (1974), Hornbuckle (1978),Davidson (2003) and Holt (2007). Abnormal gaitand loss of body condition are probably associatedwith either prostatic neoplasia or painful prostaticdiseases. Emesis was observed in 33.3 per cent ofanimals with prostatic disease. Vomiting has alsobeen reported in previous studies (Parry, 2006;Smith, 2008) and has been attributed to the rise inmetabolites in blood that fail to get excreted due todysuria. Hematuria, Pyuria, and purulent prepucialdischarges were clinical signs observed in thepresent study.

RESEARCH ARTICLEJ. Ind. Vet. Assoc., Kerala. 10 (1)Davidson (2003) and Kutzler and Yeager (2005).Hematuria which was observed in 20 per cent of theaffected animals may be a result of irritation causedby excess ammonia production in the bladder dueto retained urine (Johnson and Archibald, 1974).The common abnormalities on physicalexamination noted in the present study werepyrexia (33.3 per cent), dehydration (33.3 per cent),poor body condition (26.7 per cent) and caudalabdominal pain (6.7 percent). Cornell (1997),Davidson (2003), Parry (2007) and Smith (2008)described that signs like fever and cachexia arecommonly seen in infections of the prostate gland(Prostatitis/Abscess). Caudal abdominal pain(Kutzler and Yeager, 2005; Holt, 2007) is acharacteristic sign in acute inflammatory conditionof the prostate, shining a light on the fact that rest ofthe inflammatory conditions of the prostate couldbe of a chronic nature. Dehydration was one of thesigns in this study, as also noted by Parry (2006),can be attributed to the reflection of the systemicdisturbances like pyrexia and uneasiness caused bypain results in anorexia.REFERENCESCornell, K.
