怎么判断母狗是否怀孕

你养的母狗和公狗交配了？两只狗都没做过绝育？那它很有可能会怀孕。但是，并非每次交配都会使母狗怀孕（特别是在非排卵期）。所以，如果母狗和公狗交配了，要如何判断它是否怀孕了呢？本文将教你判断狗狗是否发情或怀孕！

步骤

判断母狗是否发情

1. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/3\/34\/Detect-Pregnancy-in-Your-Female-Dog-Step-1-Version-6.jpg\/v4-460px-Detect-Pregnancy-in-Your-Female-Dog-Step-1-Version-6.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/3\/34\/Detect-Pregnancy-in-Your-Female-Dog-Step-1-Version-6.jpg\/v4-728px-Detect-Pregnancy-in-Your-Female-Dog-Step-1-Version-6.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 1 确认它是否做过绝育。如果是你从小养大的母狗，你肯定知道它是否做过绝育（切除子宫）。如果是从动物救援中心领养的成年狗，你可能无法确定。未绝育的母狗每年发情2次，如果你养了它逾9个月都不曾发情，它很可能做过绝育了。^[1]
   • 发情期持续多久因狗而异，平均为18天。狗一般在6到24个月大期间第一次发情。^[2]

   • 阴户肿大：在发情期开始前不久，阴道外部通常会肿胀，直到发情期结束，持续约4周。
   • 阴道分泌物：在发情期的首7到10天，狗会排出血样分泌物。不妨在它的床铺一块白布，方便检查这些血斑。如果狗狗很爱干净，可能会花很多时间清洗阴户，所以分泌物可能不明显。接下来的7天，分泌物量减少，颜色变淡，母狗开始排卵。这是最容易怀孕的时期。发情期的最后7到10天，阴户逐渐恢复正常，分泌物减少至完全停止。^[3]
3. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/8\/8e\/Detect-Pregnancy-in-Your-Female-Dog-Step-3-Version-6.jpg\/v4-460px-Detect-Pregnancy-in-Your-Female-Dog-Step-3-Version-6.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/8\/8e\/Detect-Pregnancy-in-Your-Female-Dog-Step-3-Version-6.jpg\/v4-728px-Detect-Pregnancy-in-Your-Female-Dog-Step-3-Version-6.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 3 留意行为变化。母狗发情时，体内激素变化会改变它的行为。行为上的变化取决于它的性格。平时安静、温和的狗可能变得好动、脾气暴躁。平时很爱家的狗可能会突然想逃走，到处游荡。
   • 除了这些变化，狗狗应该没有其它问题。如果它无精打采、食欲不振、呕吐或大量喝水，请咨询兽医的意见。在罕见的情况下，子宫积脓等疾病和发情症状相似，如果不加治疗，可能会危及狗狗的性命。^[4]

确认狗狗是否有怀孕的可能性

1. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/0\/0b\/Detect-Pregnancy-in-Your-Female-Dog-Step-4-Version-6.jpg\/v4-460px-Detect-Pregnancy-in-Your-Female-Dog-Step-4-Version-6.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/0\/0b\/Detect-Pregnancy-in-Your-Female-Dog-Step-4-Version-6.jpg\/v4-728px-Detect-Pregnancy-in-Your-Female-Dog-Step-4-Version-6.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 1 回想它是否曾和公狗交配。母狗需要和公狗交配才能怀孕。回想它是否曾经这么做过，或者是否曾经离家出走，找到一只公狗交配。
2. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/a\/ae\/Detect-Pregnancy-in-Your-Female-Dog-Step-5-Version-5.jpg\/v4-460px-Detect-Pregnancy-in-Your-Female-Dog-Step-5-Version-5.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/a\/ae\/Detect-Pregnancy-in-Your-Female-Dog-Step-5-Version-5.jpg\/v4-728px-Detect-Pregnancy-in-Your-Female-Dog-Step-5-Version-5.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 2 确认和它交配的公狗是否曾经做过绝育。做过绝育或阉割后的公狗可以和母狗交配，但不能产生精子，使母狗怀孕。然而，没有绝育的公狗可以使母狗怀孕。如果可以，不妨联系公狗主人，确认这一点。
   • 如果公狗是在不久前才做的绝育，不到4周就交配，那就另当别论了。从理论上说，它的输精管里可能还有精子，会在交配时射到母狗体内。可能性或许很小，但绝非不可能。^[5]
3. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/a\/a6\/Detect-Pregnancy-in-Your-Female-Dog-Step-6-Version-5.jpg\/v4-460px-Detect-Pregnancy-in-Your-Female-Dog-Step-6-Version-5.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/a\/a6\/Detect-Pregnancy-in-Your-Female-Dog-Step-6-Version-5.jpg\/v4-728px-Detect-Pregnancy-in-Your-Female-Dog-Step-6-Version-5.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 3 记录它交配的日期。这对判断它是否怀孕十分重要。如果交配日期在3个月前，那么它不可能怀孕，因为孕期一般为62到65天（57到72天不等）。要是它当时怀孕了，90天后应该已经产下小猫了。^[6]
4. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/a\/a1\/Detect-Pregnancy-in-Your-Female-Dog-Step-7-Version-5.jpg\/v4-460px-Detect-Pregnancy-in-Your-Female-Dog-Step-7-Version-5.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/a\/a1\/Detect-Pregnancy-in-Your-Female-Dog-Step-7-Version-5.jpg\/v4-728px-Detect-Pregnancy-in-Your-Female-Dog-Step-7-Version-5.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 4 确定母狗发情的日期。这样兽医才能找出最合适的验孕方式。验孕方式有检测激素变化、生理变化或寻找子宫里是否有胚胎。哪一种方法最准确？这取决于你在狗狗交配后过了多久验孕。
   • 如果母狗交配了，但发情期仍未结束，要确认它是否怀孕还为时过早。^[7]

留意怀孕的早期迹象

1. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/b\/b5\/Detect-Pregnancy-in-Your-Female-Dog-Step-8-Version-5.jpg\/v4-460px-Detect-Pregnancy-in-Your-Female-Dog-Step-8-Version-5.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/b\/b5\/Detect-Pregnancy-in-Your-Female-Dog-Step-8-Version-5.jpg\/v4-728px-Detect-Pregnancy-in-Your-Female-Dog-Step-8-Version-5.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 1 观察狗狗是否变得嗜睡，并出现其它行为变化。许多狗主提到母狗的性格会在怀孕期间有一些变化，比如更加嗜睡及懒洋洋的，并且开始筑巢。不过，这些也有可能是假怀孕的症状（没有怀孕却出现怀孕症状）。一些假怀孕的母狗甚至会产奶，所以乳腺增大并非怀孕的确凿证据。^[8]
2. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/8\/83\/Detect-Pregnancy-in-Your-Female-Dog-Step-9-Version-5.jpg\/v4-460px-Detect-Pregnancy-in-Your-Female-Dog-Step-9-Version-5.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/8\/83\/Detect-Pregnancy-in-Your-Female-Dog-Step-9-Version-5.jpg\/v4-728px-Detect-Pregnancy-in-Your-Female-Dog-Step-9-Version-5.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 2 留意狗狗的乳头是否正在发育。乳头增大及变成粉红色，是比较可靠的怀孕迹象。
   • 怀孕的母狗在妊娠后期才会开始产奶。有的母狗在生下小狗后才开始产奶。
   • 你还是得验孕，以确认母狗是否真的怀孕。交配约4周后，如果乳头明显变成粉红色，怀孕的可能性很大，但不能只凭此下定论。^[9]
3. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/0\/00\/Detect-Pregnancy-in-Your-Female-Dog-Step-10-Version-5.jpg\/v4-460px-Detect-Pregnancy-in-Your-Female-Dog-Step-10-Version-5.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/0\/00\/Detect-Pregnancy-in-Your-Female-Dog-Step-10-Version-5.jpg\/v4-728px-Detect-Pregnancy-in-Your-Female-Dog-Step-10-Version-5.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 3 观察腰围是否慢慢变粗。和孕妇一样，母狗腰围变粗很有可能是怀孕，但需要小心求证。健康的母狗直到怀孕第50到55天，胎儿慢慢长大，占据腹部大量空间，腰围才会出现变化。
   • 狗狗在怀孕后期（约40天后）才需要补充热量。如果你怀疑母狗怀孕，早早就给它加餐，它的体重可能会增加，不过增加的只是脂肪，未必是小狗。^[10]
4. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/0\/04\/Detect-Pregnancy-in-Your-Female-Dog-Step-11-Version-5.jpg\/v4-460px-Detect-Pregnancy-in-Your-Female-Dog-Step-11-Version-5.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/0\/04\/Detect-Pregnancy-in-Your-Female-Dog-Step-11-Version-5.jpg\/v4-728px-Detect-Pregnancy-in-Your-Female-Dog-Step-11-Version-5.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 4 了解和怀孕相似的状况。在怀孕期间十分辛苦的狗狗需要帮助，不过，它也有可能不是怀孕，而是出现类似怀孕的状况，包括假怀孕和子宫积脓。假怀孕一般是发情后激素失调所致，不会危及生命。^[11] 另一方面，子宫积脓会引发败血症、器官衰竭，如果不加治疗，绝对会导致狗狗死亡。
   • 子宫积脓的症状与怀孕相似，狗狗会变得无精打采，腹部隆起。它也可能食欲不振，老是口渴（喝水量增加）。要是出现上述症状，请立刻联系兽医。^[12]

到兽医诊所验孕

1. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/d\/d1\/Detect-Pregnancy-in-Your-Female-Dog-Step-12-Version-5.jpg\/v4-460px-Detect-Pregnancy-in-Your-Female-Dog-Step-12-Version-5.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/d\/d1\/Detect-Pregnancy-in-Your-Female-Dog-Step-12-Version-5.jpg\/v4-728px-Detect-Pregnancy-in-Your-Female-Dog-Step-12-Version-5.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 1 透过腹部触诊寻找怀孕的最初迹象。兽医会摸摸母狗腹部，看看是否有小狗。这个方法至少要在交配21天后，才能做出正确判断。在怀孕初期，兽医会触碰到变粗、增大的子宫，而非小狗（这时候还是一团胶状物）。
   • 进行腹部触诊的最佳时机是第28天。这时候，小狗已经大得足以使子宫凸起，很像项链的珠串。
   • 到了第35天，充满流体的羊膜分别裹着每只小狗，摸起来就像流体状的香肠串。^[13]
2. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/8\/8a\/Detect-Pregnancy-in-Your-Female-Dog-Step-13-Version-5.jpg\/v4-460px-Detect-Pregnancy-in-Your-Female-Dog-Step-13-Version-5.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/8\/8a\/Detect-Pregnancy-in-Your-Female-Dog-Step-13-Version-5.jpg\/v4-728px-Detect-Pregnancy-in-Your-Female-Dog-Step-13-Version-5.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 2 了解腹部触诊未必准确。记住，在第28天，每只小狗的直径最多只有约25毫米，要区分子宫里的胎儿、肠胃里的食物或直肠里的粪便并不容易。而且，狗狗在紧张时会绷紧腹壁，靠触诊根本感觉不到什么，就像我们不能看透粉刷过的窗户一样。如果只有一只小狗，很容易被漏诊，或被误认为膀胱、肾脏甚至是直肠里的粪便。
   • 如果兽医建议验孕，不要过于失望，因为腹部触诊的结果并不具结论性。^[14]
3. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/b\/b3\/Detect-Pregnancy-in-Your-Female-Dog-Step-14-Version-5.jpg\/v4-460px-Detect-Pregnancy-in-Your-Female-Dog-Step-14-Version-5.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/b\/b3\/Detect-Pregnancy-in-Your-Female-Dog-Step-14-Version-5.jpg\/v4-728px-Detect-Pregnancy-in-Your-Female-Dog-Step-14-Version-5.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 3 第28天后可以验血，看看孕激素是否增加。这个测试得在第28天后进行才可靠，否则可能出现假阳性结果，因为孕激素升高也有可能是排卵期激素延迟衰退所致。然而，在第28天后，孕激素水平高肯定是怀孕了。^[15]
4. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/7\/7b\/Detect-Pregnancy-in-Your-Female-Dog-Step-15-Version-5.jpg\/v4-460px-Detect-Pregnancy-in-Your-Female-Dog-Step-15-Version-5.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/7\/7b\/Detect-Pregnancy-in-Your-Female-Dog-Step-15-Version-5.jpg\/v4-728px-Detect-Pregnancy-in-Your-Female-Dog-Step-15-Version-5.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 4 用超声波检测早期怀孕。超声波扫描是确认怀孕的热门方式，早在第18天，经验丰富的操作人员就能检测出子宫的细微变化，以及怀有多少只小狗。这个信息对分娩十分有用。
   • 第18天就能看到胎盘，第28天就能看到胎心。^[16]
   • 注意，超声波是在狗狗清醒的状态下进行的非侵入性程序。超声波仪器向狗的子宫发送一束高频声波，捕捉“回音”形成影像。这是安全的程序。狗狗腹部的毛发会被夹起来，确保探头和皮肤有良好接触。^[17]
5. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/7\/79\/Detect-Pregnancy-in-Your-Female-Dog-Step-16-Version-5.jpg\/v4-460px-Detect-Pregnancy-in-Your-Female-Dog-Step-16-Version-5.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/7\/79\/Detect-Pregnancy-in-Your-Female-Dog-Step-16-Version-5.jpg\/v4-728px-Detect-Pregnancy-in-Your-Female-Dog-Step-16-Version-5.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 5 了解不建议照X射线的原因。超声波已经在很大程度上取代X射线，成为受欢迎的狗狗验孕方式。X射线只有在第49天后，胎儿骨骼钙化了才有用。这时候做诊断算是相当晚了。从安全层面来说，X射线不会伤害子宫里的小狗，但是必须给母狗服镇静剂。根据当前的健康与安全规定，照射X射线时，仪器操作员不得留在房内。而许多母狗，尤其是大腹便便的母狗，无法静静躺着，人离开后便会起身走动，所以只能让它们服镇静剂。
   • 最好不要给怀孕的母狗服镇静剂，否则子宫里的小狗可能会有血压下降的风险。基于上述原因，现在已经不流行使用X射线验孕了。^[18]
