Hachiko Talks About How Puppies Inherit Traits The Secrets of Dog Genetics
I am Hachiko. Many know me for my loyalty but today, let me tell you something useful about us dogs: How do we inherit our looks and personality? Why do puppies turn out the way they do?

When two dogs have puppies, each parent passes on half of their genes to each pup.

These genes decide everything
Size. Coat color and type. Ear shape. Tail type. Personality traits. Health risks.

Dominant vs recessive genes
Some traits are dominant this means if one parent has them, the puppy is very likely to show them. Others are recessive they only appear if BOTH parents carry the gene.

For example
Curly hair is dominant. Straight hair is recessive. Black coat color may be dominant in some breeds. Rare colors or patterns may only appear if both parents carry those hidden genes.

That’s why sometimes a puppy looks very different from its parents because of genes from grandparents or great grandparents!

Purebred vs. mixed breed
→ When both parents are the same breed (purebred), puppies will mostly follow the breed standard.

→ When two different breeds mix, puppies can inherit a mix of traits sometimes predictable, sometimes a surprise.

Example
→ Labrador + Poodle → Goldendoodle Some pups will have curly hair, others wavy it depends on which genes were passed.

Which parent affects puppies more?

→ Both parents contribute equally (50%-50%).

→ But sometimes certain traits from one side can be more “dominant” not because of love or care, but due to genetics.

And what about behavior?

Personality has two parts
✅ Genetics some breeds naturally tend to be calm, playful, alert, or protective.

✅ Training & Environment this shapes how a dog will behave in real life.

A shy puppy can grow confident with the right care and a bold puppy can become gentle if raised kindly.

So, every puppy carries a story from their parents and their ancestors. Some surprises may come from generations ago. That is the magic of life, and of dogs.

And that, I tell you as Hachiko from a heart that knows loyalty is also passed down...
