惧怕是一种对外来或内在的无法掌握而又可能危及到自身安全刺激的一种应激反应，也是犬对危险事物的一种本能的反应。正常的惧怕心理是犬进行自我保护的有效措施，而对并不危及自身安全的事物的惧怕则是一种心理病态，这种病态会导致犬过分胆怯，忧心忡忡以至不能正常生存。 相似文献

犬股骨骨折的诊断与治疗 总被引：1，自引：0，他引：1
犬骨折以四肢骨多发,多因外伤引起,也可因奔跑、扭闪、急停等肌肉强烈收缩而引发骨折或病理性骨折.本研究采用询问病史、体格检查和x线检查等方法对1只7月龄苏格兰牧羊犬的股骨远端骨折进行诊断,应用髓内针内固定方法对该病犬进行治疗.过程如下:该犬主人在室外溜犬时,一辆出租车将该犬撞倒,主人将其带回家后,发现该犬右后肢不敢着地,用手触摸右后肢,犬躲避、惨叫,并伴有精神沉郁,喜卧,食欲减退.体格检查,该犬站立时右后肢不敢着地,行走时3肢跳跃前进;心、肺、腹部检查未发现异常;2前肢和左后肢运动和感觉均正常,右后肢膝关节上方明显肿胀,拒绝触摸;右后肢侧位X光片显示股骨远端骨干骨折,并且有明显的移位,膝关节正常;血常规脸查正常.综合病史、体格检查和X线检查结果,诊断为犬股骨骨折.应用髓内针内固定方法对该病犬进行治疗,术后石膏外固定患肢,全身应用抗生素,加强护理.手术1个月后,该犬已能正常行走,恢复良好. 相似文献

犬对人的支配性攻击行为这是一种很常见的异常攻击行为。它与主人的行为有直接关系。有些犬咬它的主人不是由于惧怕或疼痛,而是希望支配它的主人。具有这种异常攻击行为的犬,不服从主人的命令。当它们表现不好,撕咬家具、衣物,而主人试图将它们放到门外或进行其他惩罚时,它们就吠叫不止,甚至抓咬主人的鞋袜等以示反抗。有时,对家庭其他成员也如此。调教方法直接调教法犬在其群体生活中,通过力量 相似文献

约克夏犬。该犬是一只很吸引人的玩具型犬种。迷人又聪明,个子虽小,却很勇敢、忠诚又富感情的犬只。生气勃勃,冲动,勇敢,但是固执已见。友善,倔强,好动,动作敏捷且轻快,对主人热情、忠心,对于陌生人则退避。他很容易和家里的成员相处,包括猫和其他犬只。虽然只是小小的个子,一旦打起架来,可是毫不畏惧、退缩。具有支配性,会毫不犹豫地攻击其他的犬,即便是比自己体型大的犬,他也不会表现出胆怯。对饮食要求较高,和爱动的孩子相处得不好。需要很严格的培训,才可以控制他。可以作优良的看家犬以及家庭犬。不户户外牵遛,短距离运动即可。定期清洁牙齿、眼睛和外耳道。刷毛和干洗是每天必须,保持毛发贴地即可。听觉灵敏,只要有一点点异声,马上会报告主人。 相似文献

Evidence for the non-involvement of the uterus in the lifespan of the corpus luteum in the cyclic dog 总被引：1，自引：0，他引：1
Progesterone levels in peripheral blood of dogs were analysed during the cycle in which hysterectomy (n = 5) or sham surgery (n = 3) was performed as well as during the cycle of dogs (n = 5) hysterectomized at least one year prior to this study; the data were compared with the findings in control dogs (n = 3). The averages of the duration of the luteal period observed in the three experimental groups were not significantly different from those of control dogs. Immediately after surgery, the progesterone level decreased from 25 to 50% of the presurgical level, but returned to presurgical level in about four days. Prolactin levels were elevated for about 30 h after surgery. Nevertheless, the averages of the mean prolactin levels for each animal during the luteal period of the experimental groups were not significantly different from those of control dogs. It is concluded that in the dog, the uterus is not involved in the lifespan of the cyclic corpus luteum. 相似文献

嗅源是军犬嗅觉作业训练的依据.军犬鉴别中嗅源能力的培养在整个鉴别训练中占有重要地位,关系到鉴别训练的成败和鉴别能力的提高.所以,军犬在嗅认嗅源时必须按照训犬员的指令充分、细致地感受嗅源气味,并且对嗅源气味产生兴奋反应.如何培养军犬充分嗅认嗅源以及及时解决嗅认过程中出现的问题,成为我们进行鉴别训练的关键.…… 相似文献

As there is no statistical evidence that saddle fit influences the load exerted on a horse's back, this study was performed to assess the hypothesis that the width of the tree significantly alters the pressure distribution on the back beneath the saddle. Nineteen sound horses were ridden at walk and trot on a treadmill with three saddles differing only in tree width. Kinetic data were recorded by a sensor mat. A minimum of 14 motion cycles were used in each trial. The saddles were classified into four groups depending on fit. For each horse, the saddle with the lowest overall force (LOF) was determined. Saddles were classified as "too-narrow" if they were one size (2 cm) narrower than the LOF saddle, and "too-wide" if they were one size (2 cm) wider than the LOF saddle. Saddles two sizes wider than LOF saddles were classified as "very-wide". In the group of narrow saddles, the pressure in the caudal third (walk 0.63 N/cm(2)+/-0.10; trot 1.08 N/cm(2)+/-0.26) was significantly higher compared to the LOF saddles (walk 0.50 N/cm(2)+/-0.09; trot 0.86 N/cm(2)+/-0.28). In the middle transversal third, the pressure of the wide saddles (walk 0.73 N/cm(2)+/-0.06; trot 1.52 N/cm(2)+/-0.19) and very-wide saddles (walk 0.77 N/cm(2)+/-0.06; trot 1.57 N/cm(2)+/-0.19) was significantly higher compared to LOF saddles (walk 0.65 N/cm(2)+/-0.10/ 0.63 N/cm(2)+/-0.11; trot 1.33 N/cm(2)+/-0.22/1.27 N/cm(2)+/-0.20). This study demonstrates that the load under poorly fitting saddles is distributed over a smaller area than under properly fitting saddles, leading to potentially harmful pressures peaks. 相似文献

Observations on the Pathology of the Spleen of the Cat 总被引：1，自引：0，他引：1
Abstract— Lesions were found in the spleen of four of sixty-three cats examined post mortem in the department, and comprised two examples of lymphosarcoma, one of chronic fibrinous peritonitis and one of subcapsular haematoma. Abnormalities were found in two cat spleens received from veterinary surgeons in general practice. In one cat the abnormalities were an haemangiosarcoma with secondary deposits in the liver and in the other extensive mast cell infiltration. In addition lesions were detected in the spleen of three of eighty-seven cats examined post mortem in general practice. The lesions were: multiple secondary deposits of adenocarcinoma from a primary tumour of the mammary gland, a ruptured spleen and a foreign body below the splenic capsule. Résumé— L'examen microscopique de soixante-trois chats pratiqué dans le service a permis de rencontrer quatre fois des lésions de la rate, dont deux lymphosarcomes, une péritonite capsulaire fibrineuse et un hématome sous-capsulaire. D'autre part des lésions ont été trouvées dans deux rates de chat expédiées par des vétérinaires exerçant en pratiaue générale. Chez un chat il s'agissait d'un htmangiosarcome avec métastases hépatiques et chex l'autre d'une infilt ation diffuse par des mastocyta. De plus, on a rencontré des llésions dnas la rate de trois chats parmi quatre-vingt sept autopsies effectuées dans le cadre d'une clientèle génárale. Ces iésions étaient dés métastases multiples d'un adénocarcinome dont la tumeur primitive siègeait dam la glande mammaire, une rupture de la rate et un corps érangers sou capsulaire. Zusammenfassung— Läsionen der Milz wurden bei vier von dreiuiidsechzig in dieser hbteilung sezierten Katzen gefunden, und zwar in zwei Fällen ein Lymphosarkom, in einem Falle eine chron-ische fibrinöse Peritonitis und in einem ein subkapsuläres Hématom. Anomalien fanden sich auch in der Milz von zwei Katzen, die aus der tierxrztlichen Praxis eingesandt wurden. Bei der einen Katze war dies ein Hämangiosarkom mit Metastasen in der Leber, bei der anderen eine weitläufige Infiltration der Mastzellen. Außerdem wurden bei drei von siebenundachtzig in der Praxis sezierten Katzen Milzläsionen gefunden. Diese bestanden am multiplen Metastasen eines Adenokarzinoms der Brustdrüse, einer Milzzerreissung und einem Fremdkörper unterhalb der Milzkapsel. 相似文献
