Non-neutered dogs and females in heat

When unneutered dogs detect a dog in heat, you will notice dramatic changes in their behavior and overall well-being.

Perros relacionándose.

When unneutered dogs detect a dog in heat, you will notice dramatic changes in their behavior and overall well-being. Unless we meet the neighbors and they tell us that “Lola” is in heat, the vast majority of the time we don't even know.

Unneutered males detect females in heat at 4km round

A male can sniff the pheromones of a female in heat from a great distance (it can be up to 4km). Within a radius of 4 km can you imagine how many females can get into heat at different times?

Bitches don't sync to get into heat all at the same time but this week there may be a dog one block away in heat, next week another three blocks, tomorrow another just around the corner and so on.

An uncastrated male dog will be detecting all those females in heat, over and over again, and suffer strong changes that will lead him to fall into one or more of the following situations:

Frustration and irritability

  • Every time a dog perceives the smell of a female in heat, it will have an increase in testosterone production .
  • Testosterone production is also accompanied by an increase in other stress-linked hormones such as cortisol. This causes the dog to be more irritable and since it can not reach the female in heat, then its level of frustration will also increase.
  • Constant hormonal changes in a non-castrated male, are one of the main factors that cause a dog to live in chronic stress. As in humans, this can lead to serious diseases and conditions, as well as diminish the quality of life.

Depression and crying

  • Many dogs really suffer the fact of not being able to follow and reach the scent that leads them to the female in heat and this leads them to stop eating, to stay thrown out without desire to do anything as well as to cry or howl constantly.
  • The culprit - again, hormonal changes. The howls and/or barking of a desperate and depressed male can cause problems with neighbors.

Escapism and accidents

  • Females in heat mark more than usual to attract males that are nearby.
  • With the super smell of dogs, a male can try to follow the trail of that scent and feel so attracted and desperate to find it that he can try to escape from home.
  • Many dogs are lost by following the trail of a female in heat, whether they escape from home, flee in the park, break leashes, cross streets and move away.

All of the above can result in terrible accidents such as:

  • run over
  • definitive loss of your dog (by death or loss)
  • unplanned pregnancies in
  • dogs
  • abandonment of pregnant dogs puppies
  • in the street
  • fights between male dogs because they are all smelling the female in heat and they are all undergoing hormonal changes... etc.


  • A male who has detected the scent of a female in heat, will mark more.
  • You probably even get to dial inside the house in places you don't get used to.
  • This is a behavior that the male cannot contain and is totally natural given the situation.


  • A dog who is suffering stress levels about which we already talked about in previous paragraphs, will be much more distracted than usual.
  • This is one reason why many dogs seem “disobedient” when it is actually chronic stress and hormones that have them “distracted” and “confused”.

How do you remove it?

Since we're talking about hormonal changes, there's really not much you can do, except take your dog on vacation and “cross your fingers” so that there isn't a female in heat in that place.

 We might think the solution would be to “cross” your dog and allow him to breed but

Crossing a male to “meet” hormonal demands, will not make the problem disappear why?

  • Because as we already mentioned, there are constantly females that go into heat and having achieved “success” once, your dog will be even more anxious every time it detects the smell of pheromones.
  • So “crossing” it will not fix anything, in fact it will worsen the behavior and its emotional state.

It is best to sterilize your dog by performing a complete castration

  • Vasectomy will not prevent the production of hormones and will not benefit your dog at the level of health and emotional balance.
  • Chemical castration is a procedure that “atrophies” testicular function (an injection is given into the dog's testicles) and eventually involves leaving those tissues inside the dog, which in the long run can cause tissue necrosis and/or the appearance of tumors.
