Perhaps you've had to put up with a moody, uncooperative teenager. You may well have been one yourself. A new study suggests that dogs go through a similar phase of stubbornness and disobedience when they hit puberty at about eight months old.
Looking at the behaviour of a total of 378 canines, researchers found that the animals were more obedient and more responsive either side of that eight-month mark but only when it came to their owners, not to less familiar trainers.
So not only do dogs appear to have a difficult adolescence just like we do, they also share the frustration that we often feel towards our parents or caregivers when we hit our teenage years. That has big implications for long-term canine care and sheltering.
This is a very important time in a dog's life, says animal behaviour researcher Lucy Asher, from Newcastle University in the UK. This is when dogs are often rehomed because they are no longer a cute little puppy and suddenly, their owners find they are more challenging and they can no longer control them or train them.
来自英国纽卡斯尔大学的动物行动研讨员Lucy Asher说： 这是狗狗性命中很主要的时代，通常都是在这时给它们找新主人，因为它们不再是小狗崽了，主人突然发明它们很让人伤头脑，不好进行把持或训练。
But as with human teenage children, owners need to be aware that their dog is going through a phase and it will pass.
In one experiment with 93 Labrador retrievers, golden retrievers and their cross breeds, the pooches at eight months old were found to take longer and be more reluctant to respond to a 'sit' command given by their caregiver than they were when just five months old. The eight-month-olds didn't show the same obstinance when the command was given by a stranger, though.
在对93只拉布拉多、金毛和它们杂交滋生出的狗狗进行实验时发明，与5个月大的狗狗相比，8个月大的狗狗要花更多时光、也更不愿意对主人给出的 坐 的指令做出反映。但是在生疏人产生指令时，8个月大的狗狗并没有表示出雷同的执拗。
The researchers found further evidence of this effect in survey data gathered on 285 Labradors, golden retrievers, German shepherds and their cross breeds. Dog owners and trainers less familiar with the dogs were asked to evaluate the animals' 'trainability' by answering questions on obedience and how quickly commands were responded to.
研讨人员从285只拉布拉多、金毛、德国牧羊犬和它们杂交滋生出的狗狗身上收集到了调查数据，从中发明了能进一步证明这种反映的证据。他们让狗主人和对狗不太熟习的训导员通过答复问题来评价这些狗狗的 可训练性 ，问题涉及狗的遵从性，以及对指令的反映速度。
Again, the caregivers ranked their dogs as less obedient at eight months old compared with five months old or 12 months old. The trainers reported that obedience increased between the ages of five months and eight months.
