Eventually even the cutest pup will grow up. In addition to physical growth, this also includes changes in behavior as well as sexual maturity and the associated interest in the opposite sex. In the following, we explain when puppies become sexually mature and how you can recognize this in your four-legged friend.
Key facts at a glance
- Puppies of large dog breeds mature later than their smaller counterparts.
- Male puppies usually become sexually mature between the fifth and eighth month of life.
- Female puppies usually become sexually mature at six to twelve months.
The race decides the time of sexual maturity
When a puppy becomes sexually mature depends, among other things, on the respective breed. Small four-legged friends usually reach puberty a little earlier and therefore reach their sexual maturity earlier. In large dogs, on the other hand, this development starts a little later, so that puppies of these breeds take longer to reach sexual maturity.
Male puppies become sexually mature earlier
In addition to the breed, the sex of the puppy also plays a major role in terms of sexual maturity. Males usually reach puberty between the ages of five and eight months, while females usually reach sexual maturity between the ages of six and twelve months.
Behavioral changes in sexually mature males
While puppies do not yet differentiate between female and male conspecifics, male dogs develop an increasing interest in the opposite sex during puberty. At the same time, other male dogs are suddenly perceived as competitors.
Also, during this time, you will soon notice your growing puppy trying to lift its legs and slowly but surely beginning to mark its surroundings with its scent tag on walks.
Another sure sign that a young male is about to become sexually mature are attempts to mate, which may well even end up killing your leg or a sofa cushion.
Behavioral changes in sexually mature bitches
In bitches, puberty is primarily noticeable in the form of the first heat, which is accompanied by bleeding, frequent urination and licking of the genitals. However, it can also happen that the first heat is very unremarkable.
Much like their male counterparts, female puppies that become sexually mature develop an increasing interest in the opposite sex. In contrast to males, however, this interest is limited to the times when she is in heat. Depending on the breed, this is the case for healthy animals once or twice a year.
Train sexually mature dogs instead of neutering them
If a dog is not to reproduce, it may make sense to consider neutering the four-legged friend. However, one should not assume that spaying will change undesirable behaviors. It is important to start training early and to set limits for the dog when it comes to reproduction. Doing this consistently will reduce stress and even keep intact males and females together. Not unsupervised, of course.
Neutering a dog can have some health benefits but should always be very well coordinated with the vet or trainer.
Puppies on the way to sexual maturity – our conclusion
When puppies become sexually mature, the little four-legged friends can be very exhausting. However, as the owner, you should always be aware that this phase is also very exciting for your dog. Nevertheless, you should of course not let your puppy get away with everything and always set clear boundaries.
