As the physical signs of oestrus subside, you may notice that your dog starts to become clingy or restless due to the hormonal changes. The increased hormones can sometimes lead to behavioural changes including aggression, but these are very variable and differ between individual dogs. Due to the hormonal changes, you may notice a mild change in appetite in your dog, but this is not something to be overly concerned about. She may display the following symptoms: Whining and will appear obviously distressed, nesting – she’ll probably try and nest anywhere and everywhere, she may become possessive of objects or toys and might also carry these around like babies, increased clinginess. Once the testicles descend and his testosterone levels begin to rise, the puppy will start to lift their leg to urinate.

The hormones oxytocin and vasopressin influence canine social behaviors and aggression. Service dogs, bred for their placid temperament, have significantly higher levels of oxytocin in their blood than the average pooch. Those dogs that were more aggressive towards other dogs, however, had more vasopressin. Aggressive dogs had higher plasma vasopressin levels than control group dogs and tended to respond aggressively to the models. The study also found that service dogs, specifically bred for their calm and easy-going temperament, had especially high levels of oxytocin, a hormone associated with familial bonding after childbirth. This contrasts with the dogs with a history of aggressive behavior and elevated level of vasopressin. If vasopressin is a key factor in determining aggression in dogs, it could open new possibilities for managing behavior. However, the next step in the research process is determining if the hormone drives behavior, or is merely a result of existing aggressive tendencies.

Aggression is a combination of both nature and nurture. Early life experiences can shape adult aggression in dogs, but so can the dogs’ temperament, a characteristic partly controlled by hormones. Levels of the hormones oxytocin and vasopressin influence canine social behaviors and aggression. Service dogs, bred for their placid temperament, have significantly higher levels of oxytocin in their blood than the average pooch. Those dogs that were more aggressive towards other dogs, however, had more vasopressin. Vasopressin is the culprit behind male prairie voles becoming aggressive towards other voles after they build a nest and begin mating. Block vasopressin and the male voles shifted back to their more peaceable selves. The aggressive dogs growled, lunged, and barked more at the stuffed dogs than their non-aggressive counterparts and they also had significantly more vasopressin in their blood.

Hormonal surges can have some very noticeable effects on our canine companions’ behaviour, so here’s what to look out for after a few months. Depending on breed, around the four month mark, male puppies start to produce ever-increasing amounts of testosterone. These increased hormones lead to more energy and playfulness, as well as more exaggerated responses to almost everything they encounter. Puppies usually become more bold and adventurous, increasingly interested in their surroundings. In female dogs, the increasing levels of oestrogen can cause them to appear irritable or annoyed. The hormones flooding our pups’ bodies can cause them to display aggression towards other dogs. Disobedience and destructiveness can be common behavioural challenges seen during this period. These hormonal surges can cause our puppies to become much more distracted, reactive and guarding.

Hormones are chemical messengers that have many different functions. The effects of hormones in the body are wide-ranging and varied. Hormones function to keep factors such as temperature and blood sugar levels within certain ranges. Sometimes, pairs of hormones with opposite functions work together to keep body functions in balance. Endocrine system diseases can develop when too much or not enough hormone is produced, or when normal pathways for hormones to be used and removed are disrupted. Diseases caused by overproduction or excess of a hormone often begin with the prefix hyper. Diseases caused by a lack or deficiency of a hormone often begin with the prefix hypo. In many cases, the abnormal gland not only overproduces hormone, it also does not respond normally to feedback signals. Disorders resulting in signs of reduced endocrine activity may also develop because tissues distant from the hormone source are disrupted.

Dogs can smell pheromones and with pregnancy or after a miscarriage, there’s a change in their owner’s scent. Such changes in a person’s hormonal chemistry can affect a dog’s behaviour. People also change their behaviour after a miscarriage, they become sadder, maybe even desperate. The dog doesn’t understand this change and needs time to get used it. A dog’s behaviour will likely revert back to normal once the person’s hormonal levels readjust after an event such as a miscarriage. Usually, the expert said, the dog will be his or her old self within a few weeks, sometimes days. Dogs notice when change is in the air. We don’t have scientific data on whether dogs know what this change means, but from their behaviour we can tell that they obviously know something is different.
