Here's why:
* Genetics: Whether or not a dog's ears stand up is primarily determined by their breed genetics. Certain breeds are predisposed to having erect ears, while others have floppy ears.
* Cartilage Development: Ears stand up due to cartilage development, which is influenced by genetics and the dog's overall health.
* No Impact: Touching a puppy's ears has absolutely no effect on the development of the cartilage in their ears.
However, there are a few important points to consider:
* Ear Cropping: In some cases, people intentionally crop a dog's ears for cosmetic or functional purposes. This is a surgical procedure that permanently alters the appearance of the ears and is controversial.
* Ear Infections: It's important to keep your puppy's ears clean and free from infections. If you notice any redness, discharge, or excessive scratching, consult a veterinarian.
In conclusion, don't worry about touching your puppy's ears. It won't affect whether or not they stand up!
