Some people say that this breed becomes calmer by the time they reach 3. Others will tell you that their dog went crazy for a while, then mellowed out when they were around 5-6 years old.
However, one expert says that nothing really changes after a Shiba Inu reaches 1 year of age and it has nothing to do with child development or aging (whatever you may have heard). Shiba Inu’s temperament is mostly dictated by the combination of genes that the dogs carry. This is not necessarily related to human behavior, and it’s really hard to scientifically prove whether any behavior can be related to one or two particular genes. In fact, there are a lot more behavioral traits that are controlled by different sets of genes and they can be inherited from either parent. Some are more influenced by heredity than others, though.
Nowadays we understand that genetics play a major role in shaping dogs’ personality. For example, if you have a hyper excitable Shiba Inu that is easily agitated around strangers, take a look at its parents and other relatives. If they all seem pretty calm for Shibas, it could be that the dog is simply over-sensitive and has a low threshold for stimulation. It’s logical to think that your puppy’s parents are not going to produce an overly aggressive or extremely calm dog. Usually, dogs inherit more of their temperament from their mothers than from their fathers.
Since parents can have different temperaments, you can also take it into consideration when you’re bringing your puppy home. If the breeder keeps several Shiba Inu puppies together from the same litter, you can find out which one is likely to be more aggressive. Some dog owners even prefer certain dogs because they know that some are more of a calmer type than others, and they’d rather not bring home a puppy that might be more difficult to train later on in life.
It is important to mention that this breed’s reactivity and sensitivity can be triggered by its natural environment. For example, if your Shiba Inu lives in a busy city full of loud and unfamiliar noises, he may be agitated and quick to act defensively. If you want to keep him calmer, you should move him somewhere quieter or go for walks every day.
However, it is virtually impossible to totally eliminate a shiba inu’s natural reactions because it is more inherited from his ancestors than due to environmental stimuli. Do not expect your dog to be completely calm if you move it from a noisy city to a quiet countryside.
What you can do is change your dog’s surroundings all the time or create a quiet and familiar environment inside of the home. Do not make your dog think that he is going to be able to make mischief at all times, but try to create an atmosphere where he feels comfortable at all times. Some dogs can get mad if they are not allowed to go outside at certain times during the day. Others might be really excited to see their owners when they come home so they should be rewarded with enthusiastic greetings and lots of attention. If you can’t train your dog to know exactly what is expected, then try changing the circumstances every time so that he will never become bored.
Another thing that you should do is to make sure that your puppy is getting enough exercise every day. He needs to be taken on walks, fed healthy food and exercised both mentally and physically. If you are in a hurry to train your dog, then use positive reinforcement during training sessions and try not to raise your voice when he is being mischievous.
So there we have it, genetics really do play a major role in shaping your dog’s personality, and there’s no way you can change the way he is once he grows up, unless you want to spend a whole lot of money on therapy.
